Remarks

This is a fully managed implementation of SHA3-256 based on the Keccak sponge construction. It does not rely on OS or hardware cryptographic APIs, ensuring deterministic behavior across all platforms and runtimes.

SHA3-256 produces a 256-bit (32-byte) hash value.

Methods

Create()

Creates a new instance of the SHA3_256 class.

public static SHA3_256 Create()

Returns

SHA3_256

A new SHA3-256 hash algorithm instance.

HashData(in ReadOnlySequence<byte>)

Computes the SHA3-256 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 SHA3-256 hash.

HashData(ReadOnlySpan<byte>)

Computes the SHA3-256 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 SHA3-256 hash.

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

Computes the SHA3-256 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 SHA3-256 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.
