SHA224 class

The SHA224 class represents the SHA-224 hash algorithm, which is a variant of SHA-256.

SHA-224 is a cryptographic hash function that produces a 224-bit (28-byte) hash value from an input message. It's a variant of SHA-256 and follows a similar implementation with a different initial hash value and digest length.

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.

inherited

cleanSavedState(SHA256State savedState) → void

Clean up and reset the saved state of the hash object to its initial state. This function erases the buffer and sets the state and length to the default values. It is used to ensure that a previously saved hash state is cleared and ready for reuse.

inherited

digest() → List<int>

Generates the final hash digest by assembling and returning the hash state in a List

inherited

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

Finalizes the hash computation and stores the hash state in the provided List

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → SerializableHash<HashState>

Resets the hash computation to its initial state.

inherited

restoreState(SHA256State savedState) → SerializableHash<HashState>

Restores the hash computation state from a previously saved state.

inherited

saveState() → SHA256State

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

inherited

toString() → String

A string representation of this object.

inherited

update(List<int> data, {int? length}) → SerializableHash<HashState>

Updates the hash computation with the given data.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

hash(List<int> data) → List<int>

Computes the SHA224 hash of the provided data.
