![]() As of February 2016 the development of OpenKeychain is more active than that of APG. However, this process stopped in March 2014, while the OpenKeychain project continued to release new versions. Some of the new features and improvements were subsequently merged back to APG. In September 2013 a fork of APG was released, version 2.1 of OpenKeychain. In the light of the global surveillance disclosures this lack of development was viewed critically by the community. OpenKeychain īetween December 2010 and October 2013 no new version of APG was released. These tutorials generally reference APGs interaction with the K-9 Mail Android e-mail client. Several tutorials have been written which instruct new users in how to set up APG on an Android phone. The development has been picked up by OpenKeychain.Īfter its initial release in June 2010, it has gained a strong following with over 2000 reviews and over 100,000 installs from the Google Play store. The specific implementation in APG relies on the Spongy Castle APIs.ĪPG has not been updated since March 2014 and is no longer under active development. In the same manner, if a file is received from another user and its credentials are saved, the receiver can verify the authenticity of that file and decrypt it if necessary. The application allows the user to store the credentials of other users with whom they interact, and to encrypt files such that only a specified user can decrypt them. This allows users to encrypt, decrypt, digitally sign, and verify signatures for text, emails, and other files. Android Privacy Guard Initial releaseġ.1.1 (March 24, 2014 8 years ago ( ) ) Īndroid Privacy Guard (APG) is a free and open-source app for the Android operating system that provides strong, user-based encryption which is compatible with the Pretty Good Privacy (PGP) and GNU Privacy Guard (GPG) programs. It is not to be confused with the permission management app Privacy Guard in Cyanogenmod and LineageOS. Issues like this prompted Google to amend their OEM agreements to incorporate requirements for regular security patches.This article is about the OpenPGP compatible Android app. While most average consumers would not seemingly care about this, there is no denying that this was a breach of trust on the part of the OEMs. However, researchers found a significant patch-gap between the security patch level reported on the phone and what vulnerabilities the phone was actually protected against. Whenever Google rolls out a monthly security patch, OEMs are required to fix all the vulnerabilities outlined in that month's security bulletin if they want to claim that their device is secure up to that monthly patch level. Unfortunately, as well-intentioned this change might be for the end users, some OEMs were failing to fully roll out all of the security patches for their devices. ![]() Monthly security patches provided a quick way for concerned users to judge how "secure" and "up-to-date" their device really was. At that time, Android was infamous for its fragmentation issues, which negatively impacted how security vulnerabilities could be patched and then quickly distributed to devices. The introduction of monthly security patches for Android was a welcome and much-needed move from Google.
