Class Keccak512

Namespace
CryptoHives.Foundation.Security.Cryptography.Hash
Assembly
CryptoHives.Foundation.Security.Cryptography.dll

Computes the Keccak-512 hash for the input data.

public sealed class Keccak512 : KeccakHashCore, ICryptoTransform, IDisposable, IResettable
Inheritance
Keccak512
Implements
Inherited Members

Remarks

This is the original Keccak-512 algorithm, which differs from SHA3-512 in the domain separator byte (0x01 vs 0x06).

Keccak-512 produces a 512-bit (64-byte) hash value.

Constructors

Keccak512()

Initializes a new instance of the Keccak512 class.

public Keccak512()

Fields

HashSizeBits

The hash size in bits.

public const int HashSizeBits = 512

Field Value

int

HashSizeBytes

The hash size in bytes.

public const int HashSizeBytes = 64

Field Value

int

RateBytes

The rate in bytes (576 bits for Keccak-512).

public const int RateBytes = 72

Field Value

int

Properties

AlgorithmName

Gets the name of the hash algorithm.

public override string AlgorithmName { get; }

Property Value

string

BlockSize

Gets the block size in bytes used by the hash algorithm.

public override int BlockSize { get; }

Property Value

int

Methods

Create()

Creates a new instance of the Keccak512 class.

public static Keccak512 Create()

Returns

Keccak512

A new Keccak-512 hash algorithm instance.

HashData(in ReadOnlySequence<byte>)

Computes the Keccak-512 hash of source and returns it as a new byte array.

public static byte[] HashData(in ReadOnlySequence<byte> source)

Parameters

source ReadOnlySequence<byte>

The (possibly multi-segment) input sequence to hash.

Returns

byte[]

A new byte array containing the Keccak-512 hash.

HashData(ReadOnlySpan<byte>)

Computes the Keccak-512 hash of source and returns it as a new byte array.

public static byte[] HashData(ReadOnlySpan<byte> source)

Parameters

source ReadOnlySpan<byte>

The input data to hash.

Returns

byte[]

A new byte array containing the Keccak-512 hash.

TryHashData(in ReadOnlySequence<byte>, Span<byte>, out int)

Computes the Keccak-512 hash of source and writes it into destination.

public static bool TryHashData(in ReadOnlySequence<byte> source, Span<byte> destination, out int bytesWritten)

Parameters

source ReadOnlySequence<byte>

The (possibly multi-segment) input sequence to hash.

destination Span<byte>

The buffer to receive the hash value. Must be at least HashSizeBytes bytes.

bytesWritten int

When this method returns, the number of bytes written into destination.

Returns

bool

true if destination was large enough; otherwise, false.

TryHashData(ReadOnlySpan<byte>, Span<byte>, out int)

Computes the Keccak-512 hash of source and writes it into destination.

public static bool TryHashData(ReadOnlySpan<byte> source, Span<byte> destination, out int bytesWritten)

Parameters

source ReadOnlySpan<byte>

The input data to hash.

destination Span<byte>

The buffer to receive the hash value. Must be at least HashSizeBytes bytes.

bytesWritten int

When this method returns, the number of bytes written into destination.

Returns

bool

true if destination was large enough; otherwise, false.
