SHA512 class
The SHA512 class implements the SHA-512 hash algorithm.
SHA-512 is a cryptographic hash function that takes an input message and produces a 512-bit (64-byte) hash value known as the message digest.
To use the SHA512 class for hashing, create an instance, update it with
data, and then retrieve the hash value using the digest method.
Example usage:
final sha512 = SHA512();
sha512.update(data);
final hash = sha512.digest();

Methods
-
clean(
) → void -
Clean up the internal state and reset hash object to its initial state.
override
-
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.
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) → SerializableHash<HashState> -
Finalizes the hash computation and stores the hash state in the provided
List<int>out.override -
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.
override
-
restoreState(
SHA512State savedState) → SerializableHash< HashState> -
Restores the hash computation state from a previously saved state.
override
-
saveState(
) → SHA512State -
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, {int? length}) → SerializableHash<HashState> -
Updates the hash computation with the given data.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
