Whats SSL? SSL, or secure sockets layer, is the standard technology used to secure online communications. Lets take a quick look at what SSL is and what it does to enable your secure transactions online

You know when you go to a website and see a padlock icon in your browsers address bar? That means the website is using SSL, or secure sockets layer. SSL secures your communication with the website so hackers cant eavesdrop and see your credit card number or password.

(Technically speaking, SSL is an outdated term because its been replaced by a very similar but updated technology known as transport layer security, or TLS. But people still like to use the term SSL because its been around longer and, therefore, is easier to remember.)

Today, were taking a step back from more in-depth technical articles to take a quick look at the basics: what does SSL stand for? What is SSL? How does it work? And, of course, how you can protect your own website with SSL.

Lets hash it out.

SSL stands for secure sockets layer. In the simplest terms, SSL is a technology thats commonly used to securely send data (for example credit cards or passwords) between a users computer and a website. The term also describes a specific type of digital certificate (SSL certificate) that companies use to prove they own their domain. (Well speak more about that a little later.)

SSL is a protocol (i.e., a set of rules computer systems follow when communicating with each other) that was created in the 1990s to allow web browsers to securely send sensitive info to/from a website. Nowadays, however, we rely on transport layer security (TLS) to handle these tasks, but the term SSL has stuck around and thats the term most people use. Well talk more about SSL certificates and TLS a little later in the article. But just note that since youll commonly see SSL or SSL/TLS being used interchangeably across the internet, were just going to use the term here as well to keep things simple.

If youre looking for quick rundown of what SSL is and why its important, check out our TL;DR overview section.

If you want to learn how to enable SSL/TLS on your website, just click on this link and well take you to that section of the article. But if youre interested in learning more about what SSL/TLS does and how you use it, then keep reading.

The answer to this question is easy: your browser will tell you, usually in at least two ways:

The good news is that more and more websites are using SSL to keep site visitors like you and me secure. W3Techs reports that HTTPS is the default protocol for 79.6% of all websites. This is up from around 75% back in September 2021. Nice looks were moving in the right direction.

Heres a quick visual comparison of a website thats transmitting via a secure HTTPS protocol (using SSL/TLS) versus one thats using the insecure HTTP protocol:

If the website is using HTTP, this means that any data sent from your browser to the server hosting the website risks the data being read, modified, or stolen in transit. As a website owner, its really bad news for you and your customers because it means their data is exposed and you may be liable for not securing it in the first place.

Now that you understand the basics of what SSL stands for and what it does, lets take a brief look under the hood. How exactly does SSL protect website users and data against hackers?

SSL protects data while its in transit (travelling between the users browser and the website/web server). There are actually three different things SSL does to protect website users. SSL enables secure authentication, data encryption, and data integrity assurance. This allows you to:

All of these things are made possible through a cryptographic process known as an SSL handshake (AKA TLS handshake). Much like how you introduce yourself to someone and shake their hand, your computer does the same with a websites server:

From there, some other technical steps take place that we arent going to get into right now. (Check out the previously linked article for a more in depth look at how different versions of the SSL/TLS handshake work.) Bada bing, bada boom the end result is that your browser and the website server establish a secure connection through which you can transmit sensitive data (such as using your credentials to log in to a website).

Pretty cool, huh?

Remember how we mentioned an SSL certificate is part of the SSL handshake? Yep, thats a mandatory step every website needs an SSL certificate before it can enable SSL/TLS. An SSL certificate is a digital file (issued to the website owner by a certificate authority such as DigiCert or Sectigo) that verifies them as the legitimate owner of the website.

Whats the point of that? To help you assert your digital identity in a way that other entities (users, browsers, operating systems, etc.) can verify youre legitimate and not an imposter. This way, when a user connects to your website, they know its legitimate and can establish a secure, encrypted connection.

Heres a quick example of what the SSL certificate looks like for TheSSLstore.com:

For those of you who like a little more technical knowledge about what SSL stands for: The term SSL refers to the technology (cryptographic protocol, or the instructions) that makes secure communications possible. However, people sometimes use the same term to also refer to a type of data file known as an SSL certificate (AKA a TLS certificate). This digital certificate is an X.509 file containing data that ties you or your organizations verifiable information to the domain.

As such, its also known as a website security certificate because this information (along with other key cryptographic info it contains) helps to increase the security of your websites connections.

Ever visited a website and you werent sure if it was legitimate or trustworthy? Knowing how to view the details in their SSL certificate can help you figure out what company is running the website, who they are, and whether theyre a legit entity. (After all, you dont want to share your personal and sensitive details with a potential cybercriminal!)

As you can see in the left part of the above image, this provides general information about what the certificate is used for and which entity it was issued to. The right half of the image is the Subject details, which provides additional verifiable information about our company. In this case, it provides the following information:

All of this information can easily be verified using official resources, such as the State of Floridas Division of Businesses website:

Of course, thats not all of the information that this type of digital certificate provides. It also informs you:

Now, lets really throw a wrench into things by talking more about this term we touched on earlier. TLS, or transport layer security, is a closely related internet protocol thats so closely related to SSL that its actually considered its official successor. However, there are some technical differences in how SSL and TLS work, but were not going to dive into all of that here.

What you need to know is that when youre on a website thats secure by SSL, its technically secured by TLS. Unfortunately, people often use the terms SSL and TLS interchangeably. This gets confusing because so many people and organizations ours included still tend to use the term SSL to describe both terms.

So, why do we still call it SSL? After all, its a deprecated security protocol that was replaced with TLS back in 1999 after multiple iterations (SSL 1.0, 2.0, and 3.0). Frankly, its most likely because people are slow to change. Theres a strange tendency to stick to the terms were familiar with, so its easier for people to just call it SSL instead of TLS. (I guess, to quote a common adage, if it aint broke, dont fix it.)

So, whether someone calls it SSL or TLS, unless theyre talking about it at a highly technical level, theyre generally referring to the same secure protocol that makes the padlock icon appear in your browser or the digital certificate file that plays a central role in making that occur.

Now that weve gotten all of that info out of the way, answering what does SSL stand for? you may be wondering how you can put SSL/TLS to use on your website. Good news: its really easy. Just follow these five steps to turn make your secure website reality:

Of course, once all of this is done, use an SSL/TLS checker tool to ensure that your certificate is properly installed and configured. This can help prevent surprise issues from coming your way.

Alright, that brings us to the end of this article, which we hope helped you better understand what SSL stands for. But if youve skipped ahead and are now just joining us for a quick overview, SSL (or, really, TLS) is a secure internet protocol that allows users to share their data securely with websites.

The three key processes that SSL facilitates are:

SSL, as a protocol, uses information provided by digital certificates that go by the same name (SSL certificates). Nowadays, these are technically TLS certificates, but hardly anyone actually bothers calling them that. (You know, because were all a tad lazy and its easier to call them what weve been calling them for years.). So, there you have it. Now you can show off your technical chops around the water cooler or during the next trivia night by being able to answer the question, What does SSL stand for?

What Does SSL Stand For? A 10-Minute Look at the Secure Sockets Layer - Hashed Out by The SSL Store

WhatsApp today launched the second film, part of its ongoing privacy campaign in India, focused on message privacy and WhatsApps layers of protection that come together to offer users more control and privacy over their conversations.

The film follows the launch of WhatsApps global brand campaign earlier in August that highlights WhatsApps built-in layers of privacy protections added over the years and how multiple privacy features enable people to have meaningful conversations in their most vulnerable moments.

Conceptualised by WhatsApp and directed by Jess Kohl, the film features Indian badminton star H.S. Prannoy, who was part of the team that created history by winning the Thomas Cup title in May this year. The film captures the essence of privacy and how the teams WhatsApp group, ingeniously called Its coming home gave them a safe and private space where they could not only strategise their game plan but also share their feelings in moments of self doubt. The film highlights WhatsApps privacy controls like end-to-end encrypted video calls, privacy settings like last seen and hidden online presence that promise users the privacy and security to share their most vulnerable moments and dreams that are larger than life, empowering them to live their dreams in private until they are ready to be shared with the world.

Talking about the campaign, Avinash Pant, director - marketing at Meta India, said, WhatsApps mission is to connect the world privately and this campaign highlights the multiple ways we defend privacy so users can feel free and confident with their messages. Through this film we want to celebrate our national champions who brought home the coveted Thomas Cup and demonstrate how WhatsApp provided them a safe space where they felt empowered to have private conversations even during vulnerable moments because they knew their messages were always protected and secure, no matter where they are. We want to show people the closeness thats possible with WhatsApps built-in layers of protection without compromising on the assurance of privacy and personal space to live your dreams in private until they're ready to be shared with the world.

Commenting on the film, Prannoy said, Being a part of the Thomas Cup squad was an honour and I knew to win the title as a team, we had to communicate as a team and go through those moments of hardship, emotional vulnerability, self-doubt together. WhatsApp was that safe space for us where we could have conversations, strategise and share our most private moments, thoughts and ambitions, away from the public eye. Every time I looked at the WhatsApp group name Its coming home it gave me the confidence and fervour to make my dreams a reality. In a country that loves cricket my dream was to make people love badminton as much as I do and to inspire the next generation of players to believe in themselves and the sport.

Over the last month, WhatsApp has launched an integrated brand campaign, including innovative print, OOH and digital activations to create awareness about the privacy features available on WhatsApp that provide users multiple layers of protection when messaging.

WhatsApps built-in layers of protection and privacy controls include:

1. Leave groups silently: Users will be able to exit a group privately without having to notify everyone.

2. Choose who can see when youre online: For the times you want to keep your online presence private, WhatsApp is introducing the ability to select who can and cant see when youre online.

3. Screenshot blocking for view once messages: WhatsApp is enabling screenshot blocking for View Once messages for an added layer of protection. This feature is being tested and will be rolled out to users soon.

4. Default E2EE: WhatsApp always protects your personal conversations with end-to-end encryption by default (regardless of device) so that no one, not even WhatsApp, except your intended recipient can see or hear your private personal conversations.

5. Encrypted backups: WhatsApp offers the ability to backup your chat history with end-to-end encryption so its secure and only accessible to you with a password or encryption key. No other messaging service at our scale provides this level of additional security for your messages.

6. Disappearing messages: WhatsApps disappearing messages offer peace of mind with the ability to set durations for disappearing messagings: 24 hours, 7 days, or 90 days so users can send photos and videos that disappear after they have been opened.

7. Block and report: Users can choose to stop receiving messages and calls from certain contacts by blocking them and reporting them if they are sending problematic content or spam.

8. Two-step verification: For more protection, the two-step verification feature gives users the option to set a unique six-digit PIN that can be used when registering your phone number with WhatsApp again. This optional feature adds another layer of security to their WhatsApp account.

XEdDSA and VXEdDSA

This document describes how to create and verify EdDSA-compatible signatures using public key and private key formats initially defined for the X25519 and X448 elliptic curve Diffie-Hellman functions. This document also describes "VXEdDSA" which extends XEdDSA to make it a verifiable random function, or VRF.

X3DH

This document describes the "X3DH" (or "Extended Triple Diffie-Hellman") key agreement protocol. X3DH establishes a shared secret key between two parties who mutually authenticate each other based on public keys. X3DH provides forward secrecy and cryptographic deniability.

Double Ratchet

This document describes the Double Ratchet algorithm, which is used by two parties to exchange encrypted messages based on a shared secret key. The parties derive new keys for every Double Ratchet message so that earlier keys cannot be calculated from later ones. The parties also send Diffie-Hellman public values attached to their messages. The results of Diffie-Hellman calculations are mixed into the derived keys so that later keys cannot be calculated from earlier ones. These properties give some protection to earlier or later encrypted messages in case of a compromise of a party's keys.

Sesame

This document describes the Sesame algorithm for managing message encryption sessions in an asynchronous and multi-device setting.

India is still a democracy. Or so it pretends. But its becoming indistinguishable from autocratic regimes, like those found in some of its nearby neighbors, China, Turkey, and Pakistan.

Under Prime Minister Narendra Modi, India has become indistinguishable from dozens of other abusive regimes run by dictators, all while trying to uphold the pretense of democracy. Since Modis election in 2014, the government has endlessly sought ways to stifle dissent and monitor all local internet activity. The Indian government has taken legislative swipes against VPN providers, made third party platforms directly responsible for user-generated content, and leveraged fear-inducing (but poorly defined) terms like terrorism and fake news to propose and pass laws that expand already generous government snooping powers.

Despite its best efforts, the Indian government has been unable to outlaw device and communication encryption. But that hasnt stopped it from trying. If the government cant mandate backdoors, perhaps it can force providers of encrypted communication services to allow the government to BCC itself on communications it cant force out the hands of those providing end-to-end encryption.

The government has proposed a law to bring under a legal framework the interception of over-the-top communication services (OTT), such as WhatsApp and Signal which are encrypted, according to the new draft telecommunications bill uploaded late on Wednesday.

Presumably, this will be justified with assertions about national security and fighting rampant crime and corruption. The ends are a subversion of encrypted communications under the assumption that those who utilize encryption are criminals or subversives who must be spied on to secure the nation and, perhaps most importantly, secure Modis position.

The government will decided whos affected by this, no matter what the final language of the bill says. It is seeking public feedback on the bill, but history indicates the government wont be dissuaded by commenters who think the government should not give itself this much power.

The legislation would not only target text messages, but also allow the government to piggyback on encrypted voice and video calls. This gives it an opportunity to listen in on communications made by people whod rather not create a digital paper trail of text messages.

All the government would need to do is utter the magic words (terrorism, fake news, public safety, misinformation, crime, etc.) and encrypted services would be forced to become open books. Heres the relevant language:

Under section 24 of the draft, the central and state government, or any officer specially authorised in this behalf by the central or a state government can on the occurrence of any public emergency or in the interest of the public safety if it is satisfied that it is necessary or expedient to do so, in the interest of the sovereignty, integrity or security of India, friendly relations with foreign states, public order, or preventing incitement to an offence, for reasons to be recorded in writing, by order direct that any message or class of messages, to or from any person or class of persons received by any telecommunication services shall not be transmitted, or shall be intercepted or detained or disclosed to the officer mentioned in such order.

Governments not the governed have the power to decided what is in the interest of public safety. These two parties rarely see eye-to-eye. But only one of the parties has the power to decrypt communications. The Modi government and legislators who prefer fealty to serving the public are hoping this is what the future holds: a country where encryption no longer matters because the government has the power to insert itself into conversations between citizens. Vague language will permit the intrusion. The occasional recovery of something incriminating will be endlessly touted as justification for the laws existence. And if this means providers of encrypted communications are no longer willing to offer their services in India, it will give the government what it wants, without all the hassle of prosecuting entities that refuse to subject their users to government eavesdropping.

Indian Legislators Want The Government To Be Able To Intercept Encrypted Messages - Techdirt

When people think about data security in government, they immediately think about encryption. And rightfully so: Encrypting data at rest and in motion has been a best practice for the past decade. In recent years, however, the data security arsenal has expanded to include what is becoming known as deep data inspection.

Deep data inspection goes one step deeper into data security and looks inside packaged data for threats and quality defects.

We've been trained to believe that security threats -- malicious or unintentional exploits --emerge as data is first created. What has been overlooked in many instances, however, is that data quality issues are actually an intrinsic part of data security.

Deep data inspection is analogous in many ways to network-based deep packet inspection. In the earliest days of the internet, information crossed the internet in clear text. As hacking became more common, IT managers concluded they needed to look inside individual network packets to determine whether the data contained in those packets was legitimate.

Today, data security is beginning to conduct deep data inspection on data files especially those that fuel artificial intelligence and machine learning products that make sense of todays enormous data warehouses.

A comprehensive data security strategy now must include both inspection and encryption and, in fact, it makes the most sense to start with inspection. After all, if data is encrypted before it is inspected, its akin to locking the criminal inside the house, from a security perspective.

Consider the example of a comma-separated-value (CSV) file, similar to a spreadsheet. In the world of big data, these files can contain millions of rows and columns. Data files like these are typically encrypted because they must be protected as they move across the internet and are shared from one authorized user to the next. All thats needed is an intentional or unintentional exploit in a single cell in one file for systems to be corrupted, crashed or taken over.

Its essential, therefore, to be able to scan all those rows and columns to validate that not only are there no threats hidden in the data, but that the data itself is of good quality, properly formatted and ready for glitch-free AI modeling.

And lets not underestimate the importance of data quality in AI modeling. Because of the massive size of data files, AI is an absolutely essential part of turning data into useable information for both internal and external customers. It is therefore also an essential aspect of the health and performance of the network itself.

Data doesnt have to include malicious code to have a significant financial and operational adverse effect on AI models. Possible data corruption, incomplete data volumes, formatting errors, incomplete data or duplicate data are not only expensive from a storage and network management perspective; these problems also call into question the accuracy of AI modeling that makes big data useful to begin with. Thats why poor data quality can be as much of a network problem as security exploits.

Turning back to the larger issue, theres a curious dilemma inherent in data security. Cloud service providers often underscore that security is a shared responsibility; providers are responsible for security of the cloud, and users are responsible for security in the cloud. Cloud providers commonly expect that customers will encrypt their data.

But data encryption makes it more difficult to judge the quality of data. Ironically, in many of the most secure environments in which Ive worked, data encryption is regarded as a necessary evil at best, because of the limitations it puts on being able to examine data. If a data exploit has been proven, it becomes that much harder to find it once it has been encrypted.

None of this is to say that data shouldnt be encrypted, but its important to be aware of the issues that emerge from data encryption that make exploits or data quality problems harder to detect and isolate.

A comprehensive data security strategy, therefore especially as artificial intelligence becomes a commonplace method of analyzing and using data must be rooted in an understanding that both deep data inspection and data encryption are essential to network health. And in terms of order, deep data inspection must come before data encryption to get the best value from data at rest or in motion.

Optical Encryption Market Size And Forecast To 2022 |ADVA Optical Networking SE, Ciena Corporation, ECI Telecom Ltd., Nokia Corporation, Huawei...

Sep 26, 2022(Nanowerk News) Metasurfaces, composed of nanoresonator arrays with tailored structure and subwavelength feature size, show the potential of manipulating various degrees of freedom for manipulating light, which opens a new door to the field of optical encryption.In addition, metasurface holography can encode multiple images on a single metasurface by multiplexing methods, which can improve the information capacity and further realize the applications of encryption, anti-counterfeiting with higher security and fidelity.Based on these advantages, researchers in China have now proposed an optical encryption method based on the combination of single pixel imaging and metasurface holography.Schematic illustration of single pixel imaging key for holographic encryption based on metasurface. The red dashed box on the left is the encryption process, and the blue dashed box on the right is the decryption process. The intensity signal and the metasurface are ciphertext, and the pattern sequence in the coding and the subhologram position on the metasurface are used as the key. (Reprinted with permission by Wiley-VCH Verlag)They report their findings in Small ("Single Pixel Imaging Key for Holographic Encryption Based on Spatial Multiplexing Metasurface").Through the spatial movement of the metasurface, a large number of patterns required for single pixel imaging can be generated. In addition, a single metasurface can accommodate holograms of 26 letters and 10 numbers, and there is a 50% overlap region between adjacent subholograms in the horizontal direction.Experimental results of nanoholes array metasurface. a) QR code image reconstructed by single pixel imaging based on metasurface. b) Holographic reconstructed image addressed by the string of QR code. (Reprinted with permission by Wiley-VCH Verlag)By using the reconstruction image of single pixel imaging as the addressing key, the matching of arbitrary letters and numbers can be realized on holography, which increases the capacity and freedom of information transmission.More importantly, due to the existence of overlapping regions between subholograms, more accurate illumination is required to obtain a clear reconstruction image, which greatly meets the security of optical encryption. Through the combination of single pixel imaging and holography, our encryption method can improve the security of encrypted information meanwhile improving the coverage of plaintext information.Owing to these excellent characteristics, the team points out that this novel scheme provides a new route to information encryption.

Europe Network Encryption Market Outlook 2022 And Forecast to 2031 The Colby Echo News - The Colby Echo News

Encryption is a form of data security in which information is converted to ciphertext. Only authorized people who have the key can decipher the code and access the original plaintext information.

In even simpler terms, encryption is a way to render data unreadable to an unauthorized party. This serves to thwart cybercriminals, who may have used quite sophisticated means to gain access to a corporate networkonly to find out that the data is unreadable and therefore useless.

Encryption not only ensures the confidentiality of data or messages but it also provides authentication and integrity, proving that the underlying data or messages have not been altered in any way from their original state.

Original information, or plain text, might be something as simple as "Hello, world!" As cipher text, this might appear as something confusing like 7*#0+gvU2xsomething seemingly random or unrelated to the original plaintext.

Encryption, however, is a logical process, whereby the party receiving the encrypted databut also in possession of the keycan simply decrypt the data and turn it back into plaintext.

For decades, attackers have tried by brute forceessentially, by trying over and over againto figure out such keys. Cybercriminals increasingly have access to stronger computing power such that sometimes, when vulnerabilities exist, they are able to gain access.

Data needs to be encrypted when it is in two different states: "at rest," when it is stored, such as in a database; or "in transit," while it is being accessed or transmitted between parties.

An encryption algorithm is a mathematical formula used to transform plaintext (data) into ciphertext. An algorithm will use the key to alter the data in a predictable way. Even though the encrypted data appears to be random, it can actually be turned back into plaintext by using the key again. Some commonly used encryption algorithms includeBlowfish, Advanced Encryption Standard (AES), Rivest Cipher 4 (RC4), RC5, RC6, Data Encryption Standard (DES), and Twofish.

Encryption has evolved over time, from a protocol that was used only by governments for top-secret operations to an everyday must-have for organizations to ensure the security and privacy of their data.
