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);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)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()
