Property Value

string

NonceSize

protected override int NonceSize { get; }

Property Value

Methods

SetKey(byte[], byte[])

XSalsa20 key generation: process 256 bit input key and 128 bits of the input nonce using a core Salsa20 function without input addition to produce 256 bit working key and use that with the remaining 64 bits of nonce to initialize a standard Salsa20 engine state.

protected override void SetKey(byte[] keyBytes, byte[] ivBytes)

Parameters

keyBytes byte[]

ivBytes byte[]
