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();

Implementers

Constructors

getBlockSize → int: The block size used by the hash algorithm.
no setteroverride
getDigestLength → int: The length of the digest produced by the hash algorithm.
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

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
override
finish(List<int> out) → SerializableHash<HashState>: Finalizes the hash computation and stores the hash state in the provided List
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

hash(List<int> data) → List<int>: Computes the SHA-512 hash of the provided data.
