Congratulations! However, there exists no easy way to update your signing key for an existing application, because an installed application can only take updates from an APK signed with the same key. If you are publishing a new app to the app store, then simply generate a new strong signing key and you’re done.

Migrating to a strong key for an Android app is, unfortunately, not so simple. Bernstein, Nadia Heninger, and Tanja Lange ( watch recording) How? It is conceivable the cost has fallen enough to be affordable not only by nation-state actors, but by large criminal enterprises too.įor a comprehensive talk on the state of the art (as of December 2012) when it comes to breaking 1024-bit RSA, check out the 29C3 talk FactHacks: RSA factorization in the real world with the cryptographers Daniel J. Presumably the techniques have improved by orders of magnatude, and the hardware value depreciated. So, it’s time to move on.įor an example, a decade ago the cost of building special purpose hardware capable of breaking a single 1024-bit RSA key in one year was estimated at $10 million ( Adi Shamir, Eran Tromer, On the cost of factoring RSA-1024, 2003). If anything, the deprecation year could have been extended slightly to allow the NSA a window where they had the capacity to factor 1024-bit keys and everyone was still using them.

Confidence in NIST might be shaken in light of recent revelations, but in this case increasing the RSA key size is unlikely to trigger any secret NSA backdoors. This deprecation by NIST isn’t an indication that 1024-bit RSA is compromised, instead it is a preemptive move to stay ahead of attacks. NIST’s official guidelines (PDF, page 64 and 67) deprecated 1024-bit RSA keys at the end of 2013. The evidence has been mounting for a decade. There are several good reasons to migrate off of 1024-bit RSA keys, even though there is no public proof of a 1024 prime factorization required to generate any 1024-bit key at will.

If the APK is signed by a different key, then Android will prevent installing and updating.įirst thing is to see what the current signing key is. When the package name and signing key of one APK match an installed app, then the APK is considered an update and Android will replace the installed app with the APK. If either of those are different, then Android considers it a different app. The Android security model defines an app by two things: the package name (aka packageName, ApplicationID, package) and the signing key. The purpose behind this signature is to identify the author of the application, allow this author and this author alone to make updates to the app, as well as provide a mechanism to establish inter-application trust. The Android OS requires that every application installed be signed by a digital key. It is time to update to a stronger signing key for your Android app! The old default RSA 1024-bit key is weak and officially deprecated.
