These larger numbers of iterations cause the key derivation process to take
longer, so I also moved that task to the background. andOTP now also has a
proper "issuer" field, so we make use of that as well.
Also fixes an issue where padded base32 could not be decoded. This issue is only
present for the andOTP importer as far as I know, so that's why that change is
included here.
Also fixes another issue where previously, if a user made it to the last intro
slide and then navigated back to change the security options, any changes would
be ignored.
This improves the entry icon editing flow as suggested in #252:
- Add an "Edit icon" menu item
- Save the icon even if the checkmark was not clicked
- Exit icon edit mode with the back button
Close#252.
We only use Bouncy Castle for scrypt, so replacing the security provider was a
nice to have. It's causing issues because Proguard removes Bouncy Castle
classes. As we just released a beta, this is a quick fix and we may revisit this
later.
SpongyCastle is a fork of BouncyCastle. We originally used this fork to 1) have
access to scrypt and 2) prevent a package name collision with the bundled
BouncyCastle. We don't actually need to use the fork anymore, because the
package name of the bundled BouncyCastle was changed in Android. SpongyCastle
has also gotten quite outdated in recent years.
The built-in version of BouncyCastle is replaced with the one bundled with the
app at runtime, so that we have a recent version even on older Android versions.
This also updates Gradle and the Gradle Android plugin, to fix a build error I
was running into when I added the dependency to BouncyCastle.
This fixes an issue where the existing PreferencesFragment was discarded when
restoring PreferencesActivity from instance state. This issue caused the
PreferencesFragment to no longer receive activity results. Most notably, this
resulted in 0 byte vault files being created when exporting the vault.
This'll display a warning to users who don't have automatic time synchronization
enabled on their device. Aegis will try to take the user to the right settings
menu if they tap "Yes". Users also have the option to silence the warning.

The main goals of this patch are to:
- Improve the exception handling in Aegis and the way we present errors messages
to the user when they occur.
- Write exception stack traces to the log in more places, so that the ADB logs
we ask for from our users when reporting bugs become more useful.
- Reduce the amount of times we throw a RuntimeException, particularly when an
Android Keystore operation fails.
Achieving the above goals ended up resulting in a very large refactor. The
intro and unlock flow of the app need to be retested entirely.
