0.4: Recently a weakness in Android's random generator has been found. While Passtore uses symmetric encryption, due to the way it stores keys it does rely on non-predictable random numbers for its security and is therefore affected. This version adds a fix for this flaw.
If you upgrade, it will re-generate a new keystore and re-encrypt the database on the first login. There is no need to change the master password itself.
