Methods

checkParameters({int? length, required SecretKey secretKey, required int nonceLength, int aadLength = 0, int keyStreamIndex = 0}) → void: Checks parameters for encrypt / decrypt and throws ArgumentError if any is invalid.
inherited
cipherTextLength(int clearTextLength) → int: Calculates the length of the ciphertext given a clear text length.
inherited
decrypt(SecretBox secretBox, {required SecretKey secretKey, List<int> aad = const <int>[], int keyStreamIndex = 0, Uint8List? possibleBuffer}) → Future<List<int>>: Decrypts a ciphertext.
inherited
decryptStream(Stream<List<int>> stream, {required SecretKey secretKey, required List<int> nonce, required FutureOr<Mac> mac, List<int> aad = const [], bool allowUseSameBytes = false}) → Stream<List<int>>: Decrypts a Stream of bytes.
inherited
decryptString(SecretBox secretBox, {required SecretKey secretKey}) → Future<String>: Calls decrypt and then converts the bytes to a string by using utf8 codec.
inherited
encrypt(List<int> clearText, {required SecretKey secretKey, List<int>? nonce, List<int> aad = const <int>[], int keyStreamIndex = 0, Uint8List? possibleBuffer}) → Future<SecretBox>: Encrypts a cleartext.
inherited
encryptStream(Stream<List<int>> stream, {required SecretKey secretKey, required List<int> nonce, required void onMac(Mac mac), List<int> aad = const [], bool allowUseSameBytes = false}) → Stream<List<int>>: Encrypts a Stream of bytes.
inherited
encryptString(String clearText, {required SecretKey secretKey}) → Future<SecretBox>: Converts a string to bytes using utf8 codec and then calls encrypt.
inherited
newCipherWand() → Future<CipherWand>: Constructs a CipherWand that uses this implementation and a new random secret key (that can't be extracted).
inherited
newCipherWandFromSecretKey(SecretKey secretKey, {bool allowEncrypt = true, bool allowDecrypt = true}) → Future<CipherWand>: Constructs a CipherWand that uses this implementation and the given SecretKey.
inherited
newNonce() → List<int>: Generates a new nonce.
inherited
newSecretKey() → Future<SecretKey>: Generates a new SecretKey.
inherited
newSecretKeyFromBytes(List<int> bytes) → Future<SecretKey>: Constructs a new SecretKey from the bytes.
inherited
newState() → CipherState: inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited
toSync() → DartAesGcm: Returns a synchronous, pure Dart implementation of this cipher.
