HMAC<T extends HashState> class

The HMAC class represents a Hash-based Message Authentication Code.

It computes a MAC using a given hash function with a secret key and input data.

Implemented types

• SerializableHash<T>

Constructors

HMAC(HashFunc<T> hash, List<int> key, [int? blockSize])

Creates an HMAC instance with the specified hash function and secret key.

Properties

getBlockSize → int

block size

no setter, override

getDigestLength → int

digest length

no setter, override

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() → void

Clean up the internal state and reset hash object to its initial state.

override

cleanSavedState(T savedState) → void

Clean up and reset the saved state of the hash object to its initial state.

override

digest() → List<int>

Generates the final hash digest by assembling and returning the hash state in a List<int>.

override

finish(List<int> out) → HMAC<HashState>

Finalizes the hash computation and stores the hash state in the provided out. Parameters:

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → HMAC<HashState>

Resets the hash computation to its initial state.

override

restoreState(T savedState) → HMAC<HashState>

Restores the hash computation state from a previously saved state.

override

saveState() → T

Saves the current hash computation state into a serializable state object.

override

toString() → String

A string representation of this object.

inherited

update(List<int> data) → Hash

Updates the hash computation with the given data.

override

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

hmac(HashFunc<HashState> hash, List<int> key, List<int> data) → List<int>

Calculates an HMAC using a specified hash function, a secret key, and input data.
