A .NET implementation of Salsa20, Salsa20/12, and Salsa20/8.
Warning
- You'd be better off using Salsa20 from libsodium.
- The nonce MUST NOT be repeated or reused with the same key.
- Do NOT touch the counter unless you know how Salsa20 works internally.
- I do NOT recommend Salsa20/8; the security margin is not enough. Stick with Salsa20.
