Cipher class final
An unauthenticated block-cipher mode fetched by name from the default
provider, e.g. AES-256-CTR.
Constructors
-
Cipher.aesCtr(List<
int> key) -
AES in counter mode with a 128, 192 or 256-bit
key, selected by the key length exactly like at_chops'AesCtrFactory.factory -
Cipher.named(String algorithm, List<
int> key) -
Any unauthenticated cipher
EVP_CIPHER_fetchknows, e.g.AES-256-CBC,ChaCha20.factory
Properties
- algorithm → String
-
OpenSSL algorithm name, e.g.
AES-256-CTR.final - blockSize → int
-
Block size in bytes (1 for stream-like modes such as CTR).
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- ivLength → int
-
Required IV/nonce length in bytes (16 for AES-CTR).
no setter
- keyLength → int
-
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
decrypt(
List< int> iv, List<int> ciphertext) → Uint8List -
Decrypts
ciphertextin one call. -
decryptStream(
List< int> iv) → CipherStream -
encrypt(
List< int> iv, List<int> plaintext) → Uint8List -
Encrypts
plaintextin one call. For CTR the output has the same length. -
encryptStream(
List< int> iv) → CipherStream - A streaming encryptor: call CipherStream.update repeatedly, then CipherStream.finish. Counter state carries across calls, so the concatenated output equals encrypt of the concatenated input.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
