Description
// key generation
val keyGenerator = KeyGenerator.getInstance("AES", "AndroidKeyStore")
keyGenerator.init(
KeyGenParameterSpec.Builder(alias, PURPOSE_ENCRYPT or PURPOSE_DECRYPT)
.setBlockModes(BLOCK_MODE_GCM)
.setEncryptionPaddings(ENCRYPTION_PADDING_NONE)
.setUserAuthenticationRequired(true)
.setUserAuthenticationValidityDurationSeconds(-1)
.build()
)
val secretKey = keyGenerator.generateKey()
// cipher initialization
val encryptCipher = Cipher.getInstance(CIPHER_TRANSFORMATION)
encryptCipher.init(Cipher.ENCRYPT_MODE, secretKey)
// biometry prompt invocation
val prompt = BiometricPrompt(activity, executor, listener)
prompt.authenticate(info, CryptoObject(encryptCipher))
BUILD INFO
- Device type: Samsung S10e (SM-G970F)
- OS version: Android 9
- Biometric library version: 1.0.1
- Device security configuration: only one fingerprint added
