Aead class final

An AEAD cipher bound to a key.

Constructors

Aead.aes128Gcm(List<int> key)

AES-128-GCM with a 16-byte key.

factory

Aead.aes256Gcm(List<int> key)

AES-256-GCM with a 32-byte key. Nonce: 12 bytes recommended (other lengths are accepted by GCM and passed through EVP_CTRL_AEAD_SET_IVLEN).

factory

Aead.chacha20Poly1305(List<int> key)

ChaCha20-Poly1305 (RFC 8439) with a 32-byte key and 12-byte nonce.

Properties

algorithm → String

OpenSSL algorithm name, e.g. AES-256-GCM.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

tagLength → int

Tag length in bytes (16).

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

open(List<int> nonce, SealedBox box, {List<int> aad = const []}) → Uint8List

Verifies and decrypts box. Throws AuthenticationException on any mismatch of key, nonce, AAD, ciphertext or tag.

openCombined(List<int> nonce, List<int> combined, {List<int> aad = const []}) → Uint8List

Convenience: open on ciphertext || tag.

seal(List<int> nonce, List<int> plaintext, {List<int> aad = const []}) → SealedBox

Encrypts and authenticates plaintext with nonce and optional aad.

sealCombined(List<int> nonce, List<int> plaintext, {List<int> aad = const []}) → Uint8List

Convenience: seal returning ciphertext || tag.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
