SHA256 class

The SHA256 class represents the SHA-256 hash algorithm.

SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value from an input message. It's commonly used in various security applications. This class implements the SHA-256 algorithm and provides a standard interface for hashing data and producing digests.

Properties

getBlockSize → int

block size

no setter, override

getDigestLength → int

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.

override

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.

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(SHA256State savedState) → SerializableHash<HashState>

Restores the hash computation state from a previously saved state.

override

saveState() → SHA256State

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.

inherited

Static Methods

hash(List<int> data) → List<int>

Computes the SHA-256 hash of the provided data.

override

Constants

blockSize → const int

digestLength → const int
