optimalChunkSize → int

Length of chunks that are processed in one go.

no setter

random → Random?

Random number generator used by newSecretKey for generating secret keys.

final, inherited

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, int? chunkSize, Uint8List? possibleBuffer}) → Future<List<int>>

Decrypts a ciphertext.

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

decryptSync(SecretBox secretBox, {required SecretKeyData secretKey, List<int> aad = const <int>[], int keyStreamIndex = 0, Uint8List? possibleBuffer}) → List<int>

encrypt(List<int> clearText, {required SecretKey secretKey, List<int>? nonce, List<int> aad = const <int>[], int keyStreamIndex = 0, int? chunkSize, Uint8List? possibleBuffer}) → Future<SecretBox>

Encrypts a cleartext.

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

encryptSync(List<int> clearText, {required SecretKeyData secretKey, List<int>? nonce, List<int> aad = const <int>[], int keyStreamIndex = 0, Uint8List? possibleBuffer}) → SecretBox

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() → DartCipherState

override

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.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
