Questions tagged [salsa20]

Salsa20 by Daniel J. Bernstein is a family of stream ciphers built on a pseudo-random function.

The algorithm uses XOR, rotation operations, and 32-bit addition. It is pretty fast while mapping a 256-bit key, a 64-bit nonce, and a 64-bit stream position to a 512-bit output.

Salsa20 offers speeds of around 4–14 cycles per byte, but is it parallelized?

On Wikipedia: https://en.wikipedia.org/wiki/Salsa20#cite_note-5 they wrote Salsa20 offers speeds of around 4–14 cycles per byte in software on modern x86 processors. But is it implemented that way, it performs some operations in parallel? If so, how…
