Remarks

This is the original Keccak-384 algorithm, which differs from SHA3-384 in the domain separator byte (0x01 vs 0x06).

Keccak-384 produces a 384-bit (48-byte) hash value.

Methods

Create()

Creates a new instance of the Keccak384 class.

public static Keccak384 Create()

Returns

Keccak384

A new Keccak-384 hash algorithm instance.

HashData(in ReadOnlySequence<byte>)

Computes the Keccak-384 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-384 hash.

HashData(ReadOnlySpan<byte>)

Computes the Keccak-384 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-384 hash.

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

Computes the Keccak-384 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-384 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.
