SHA512256 class
The SHA512256 class extends the SHA-512 hash function, specifically
truncating its output to 256 bits (32 bytes). It inherits the implementation
of the SHA-512 hash algorithm
Example usage:
final data = List<int>.from([0, 1, 2, 3, 4, 5]);
final sha512256Hash = SHA512256().update(data).digest();
This class allows you to compute a SHA-512/256 hash, which is a widely-used cryptographic hash function known for its security and is often used in various security and data integrity applications

Methods
-
clean(
) → void -
Clean up the internal state and reset hash object to its initial state.
inherited
-
cleanSavedState(
SHA512State 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(
SHA512State savedState) → SerializableHash< HashState> -
Restores the hash computation state from a previously saved state.
inherited
-
saveState(
) → SHA512State -
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.
