Android: Fingerprint authentication not implemented yet

See original GitHub issue

It’s possible to get if the device supports fingerprint authentication with getSupportedBiometryType() but the keychain item doesn’t use the fingerprint authentication (or provide options for doing so).

Looking at https://github.com/oblador/react-native-keychain/blob/c4b2b4dcfe4e36d2cfc86bf25d3a5af461779464/android/src/main/java/com/oblador/keychain/cipherStorage/CipherStorageKeystoreAESCBC.java#L71

The code is commented out. I’ve tried playing with this feature and uncommenting the code and even passing if the device supports fingerprint auth as an extra argument to encrypt.

However I can’t get it working and there’s nothing in the logs to suggest what is wrong.

@LinusU That’s really good.

I managed to merge some of your code into my PR. You can now encrypt without using fingerprint and decrypt using it. https://github.com/cladjules/react-native-keychain

At least, there is now a separate cipherStorage so it’s easier to manage and in a different file.

I will try and add the BiometricPromptCompat so it uses both Compat and BiometricPrompt code.

@Jyrno42 5c00a5d doesn’t have anything to do with fingerprint, right? Can you submit that as a separate pull request?

Will do

E: https://github.com/oblador/react-native-keychain/pull/150 is out
