GCM class

Galois/Counter Mode (GCM) implementation for authenticated encryption with associated data (AEAD).

This class implements the GCM mode, which provides authenticated encryption with associated data (AEAD) using a block cipher with a 16-byte block size.

Implemented types

• AEAD

Constructors

GCM(BlockCipher cipher)

Creates a GCM instance with the specified block cipher.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

nonceLength → int

Returns the length (in bytes) of the nonce required by the AEAD algorithm.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

tagLength → int

Returns the length (in bytes) of the authentication tag produced by the AEAD algorithm.

final

Methods

clean() → GCM

Cleans up resources used by the Galois/Counter Mode (GCM) instance.

override

decrypt(List<int> nonce, List<int> sealed, {List<int>? associatedData, List<int>? dst}) → List<int>?

Decrypts sealed data using the Galois/Counter Mode (GCM) with associated data (AEAD).

override

encrypt(List<int> nonce, List<int> plaintext, {List<int>? associatedData, List<int>? dst}) → List<int>

Encrypts data using the Galois/Counter Mode (GCM) with associated data (AEAD).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
