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.
override
decrypt(SecretBox secretBox, {required SecretKey secretKey, List<int> aad = const <int>[], Uint8List? possibleBuffer}) Future<List<int>>
Decrypts SecretBox and returns the bytes.
override
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>[], Uint8List? possibleBuffer}) Future<SecretBox>
Encrypts bytes and returns SecretBox.
override
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.
override
newSecretKey() Future<SecretKey>
Generates a new SecretKey.
override
newSecretKeyFromBytes(List<int> bytes) Future<SecretKey>
Constructs a new SecretKey from the bytes.
override
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() DartCipher
Returns a synchronous, pure Dart implementation of this cipher.
