AesAuthModeBuilder class sealed

Sealed base for authenticated-mode builders (AesMode.gcm, AesMode.ccm).

The concrete subtypes AesGcmModeBuilder and AesCcmModeBuilder differ in what they expose:

• GCM has a fixed tag size of 128 bits (the only value PointyCastle supports), so AesGcmModeBuilder does not expose a tagSize setter.
• CCM supports tags of 32/48/64/80/96/112/128 bits per NIST SP 800-38C, so AesCcmModeBuilder exposes tagSize with validation against that set.

Both subtypes expose aad and ivSize. Use this sealed base only as a type annotation when a function should accept either GCM or CCM.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

aad(Uint8List aad) → AesAuthModeBuilder

Sets the Additional Authenticated Data (AAD). Subtypes override this with a covariant return type so the chain stays statically typed.

cipher(FortisAesKey key) → AesAuthCipher

Builds an AesAuthCipher for this configuration.

override

ivSize(int size) → AesAuthModeBuilder

Sets the IV size in bytes. Subtypes apply mode-specific validation and return their own type via covariance.

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.
