Gmail 7.2 APK Hints At Possible S/MIME Encryption – Android Headlines

Some code found by XDA Developers in a teardown of version 7.2 of Googles Gmail APK seems to hint at enhanced encryption features planned for a future version of the app. To be clear, the mobile variant of the application already has some level of security with TLS encryption enabled by default. However, the discovered code hints at the addition of support for an enhanced encryption protocol S/MIME which is already available in the web-based version of Gmail. Bearing in mind that items found in APK teardowns dont always come to fruition, the addition of more security on the mobile side of things would match the companys goals to both make Android the most secure mobile platform and to bring more unification across its platforms.

S/MIME effectively works by creating, sending, and checking signature certificates tied to an email, so that users can verify that the sender of any such communication was actually where the message originated from. In the web-based version of Gmail, verification is shown in the form of a green lock symbol on a given email. XDA Developers conducting a teardown first noticed a block of code Enhanced encryption (S/MIME). The otherlines of code in that section appear to be related to user-side messages also linked to S/MIME encryption. It can reasonably be assumed that Google will use the same symbols in the mobile application as those used in the web version of Gmail. So the strings, as code stored in text format is called, would most likely be shown to end-users click alongside associated emails. Presumably, S/MIME messages could work similarly to how current messages relating to security do. For example, some spam emails in the current Gmail app show a boxed message which generally appears at the top of the email with a statement relating to how the message was determined to be spam in the first place and including precautions that should be taken.Layout files which generally correspondto user interface management were also discovered. The naming conventions used with the files directly correlate to those found in the encoded string messages and are listed by XDA asfz_details.xml, fz_failure.xml, fz_details_item.xml, fz_details_divider.xml, and fz_failure_background.xml.

It is always worth reiterating that not all of the code found in any APK will eventually make its way to users.However, the sheer number of discoveries in version 7.2 of the mobile application really seems to indicate very strongly that a future version will come with the advanced protocol activated. Considering the current security-minded atmosphere surround technologies in general, that would ultimately be a win-win for everybody involved.
