BLAKE2b class
Implementation of the BLAKE2b hash function that implements the SerializableHash interface.
BLAKE2b is a cryptographic hash function that produces a fixed-length hash value from input data. This class provides the internal state, buffers, and logic to perform the hashing operation.
Fields:
_state: The internal state of the BLAKE2b hash._buffer: A buffer to hold input data blocks._bufferLength: The current length of data in the buffer._ctr: A counter for block processing._flag: A flag for last node processing._lastNode: A flag indicating if this is the last node._finished: A flag indicating if the hashing process is finished._vtmp: Temporary storage for variable data._mtmp: Temporary storage for message data._paddedKey: Padded key for hash initialization._initialState: The initial state of the BLAKE2b hash.

Methods
-
clean(
) → void -
Cleans sensitive data and resets the internal state of the hash function.
override
-
cleanSavedState(
HashState savedState) → void -
Cleans and resets a saved hash state, securely erasing sensitive data.
override
-
digest(
) → List< int> -
Returns the final hash digest as a List<int>.
override
-
finish(
List< int> out) → BLAKE2b -
Finalizes the BLAKE2b hash, producing the hash digest and writing it to the given output List<int>.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reset(
) → BLAKE2b -
Resets the BLAKE2b hash instance to its initial state, clearing all internal data.
override
-
restoreState(
Blake2bState savedState) → BLAKE2b -
Restores the hash state to a previously saved state object.
override
-
saveState(
) → Blake2bState -
Saves the current state of the BLAKE2b hash function for future restoration.
override
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
List< int> data, {int? length}) → BLAKE2b -
Updates the BLAKE2b hash with the given data, optionally specifying the data length.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
