Methods
-
biometricAuthAvailable(
) → Future< BiometricAvailability> - Checks if biometric authentication is available.
-
biometricAuthAvailableWithStrength(
BiometricStrength biometricStrength) → Future< BiometricAvailability> -
Checks if biometric authentication with
biometricStrengthis available. Only Android distinguishes biometric classes. -
createKeys(
String? keyAlias, CreateKeysConfig? config, KeyFormat keyFormat, String? promptMessage) → Future< KeyCreationResult> - Creates a new key pair.
-
createSignature(
String payload, String? keyAlias, CreateSignatureConfig? config, SignatureFormat signatureFormat, KeyFormat keyFormat, String? promptMessage) → Future< SignatureResult> - Creates a signature.
-
createSignatureFromBytes(
Uint8List payload, String? keyAlias, CreateSignatureConfig? config, SignatureFormat signatureFormat, KeyFormat keyFormat, String? promptMessage) → Future< SignatureResult> - Creates a signature from raw bytes.
-
decrypt(
String payload, String? keyAlias, PayloadFormat payloadFormat, DecryptConfig? config, String? promptMessage) → Future< DecryptResult> - Decrypts data.
-
deleteAllKeys(
) → Future< bool> - Deletes all biometric keys across all aliases.
-
deleteKeys(
String? keyAlias) → Future< bool> - Deletes keys for a specific alias.
-
getKeyInfo(
String? keyAlias, bool checkValidity, KeyFormat keyFormat) → Future< KeyInfo> - Gets detailed information about existing biometric keys.
-
isDeviceLockSet(
) → Future< bool> - Checks whether the device has a screen lock configured.
-
listKeyAliases(
) → Future< List< String?> > -
Lists the aliases that have a key (
nullfor the default alias). -
