using var poly = new Poly1305(new PinnedMemory<byte>(new byte[] {63, 61, 77, 20, 63, 61, 77}, false));
using var hash = 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(hash, 0);

Constructor

Poly1305(PinnedMemory<byte> key)

Methods

Set key for digest, this is typically only used if the key changes after construction.

void SetKey(PinnedMemory<byte> key)

Get the message digest output length.

int GetLength()

Update the message digest with a single byte.

void Update(byte input)

Update the message digest with a pinned memory byte array.

void UpdateBlock(PinnedMemory<byte> input, int inOff, int len)

Update the message digest with a byte array.

void UpdateBlock(byte[] input, int inOff, int len)

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

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

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()
