Poly1305 class

The Poly1305 class represents an implementation of the Poly1305 one-time message authentication code (MAC).

Poly1305 is a fast and secure MAC algorithm used for data integrity verification and authentication. The algorithm produces a fixed-size digest of 16 bytes.

Constructors

Poly1305(List<int> key)

Constructor for the Poly1305 class.

Properties

digestLength → int

The length of the Poly1305 digest (always 16 bytes).

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

Methods

clean() → Poly1305

Cleans up and resets the internal state of the Poly1305 instance.

digest() → List<int>

Computes and returns the Poly1305 message authentication code (MAC) for the current state.

finish(List<int> mac, [int macpos = 0]) → Poly1305

Finalizes the Poly1305 authentication process and computes the authentication code (MAC).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

update(List<int> data) → Poly1305

Updates the Poly1305 authentication state with additional data from the given List<int>.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

auth(List<int> key, List<int> data) → List<int>

Computes a Poly1305 authentication code (MAC) for the provided data using the given key.
