Blake2b.NetCore

⛔️ [DEPRECATED] Please use Blake2b.Net as a replacement.

Implementation of the cryptographic hash, and mac functions of BLAKE2b. Optimized for PinnedMemory, and 64-bit platforms.

Examples

You can find more examples in the github examples project.

Hash:

var digest = new Blake2b();
using var exampleHash = new PinnedMemory<byte>(new byte[digest.GetLength()]);
digest.UpdateBlock(new PinnedMemory<byte>(new byte[] {63, 61, 77, 20, 63, 61, 77, 20, 63, 61, 77}, false), 0, 11);
digest.DoFinal(exampleHash, 0);

Mac:

var digest = new Blake2bMac(new PinnedMemory<byte>(new byte[] {63, 61, 77, 20, 63, 61, 77}, false));
using var exampleHash = new PinnedMemory<byte>(new byte[digest.GetLength()]);
digest.UpdateBlock(new PinnedMemory<byte>(new byte[] {63, 61, 77, 20, 63, 61, 77, 20, 63, 61, 77}, false), 0, 11);
digest.DoFinal(exampleHash, 0);

Constructor

Digest size restricted to 160, 256, 384, 512

Blake2b(int digestSize = 512)

Blake2bMac(PinnedMemory<byte> key)

Blake2bMac(PinnedMemory<byte> key, byte[] salt, int digestSize = 512)

Methods

Update the message digest with a single byte.

void Update(byte b)

Update the message digest with a pinned memory byte array.

void UpdateBlock(PinnedMemory<byte> message, int offset, int len)

Update the message digest with a byte array.

void UpdateBlock(byte[] message, int offset, int len)

Produce the final digest value outputting to pinned memory. Key & salt remain until dispose is called.

void DoFinal(PinnedMemory<byte> output, int outOffset)

Reset the digest back to it's initial state for further processing. Key & salt remain until dispose is called.

void Reset()

Clear key & salt, reset digest back to it's initial state.

void Dispose()
