Chacha and Salsa are two different stream cyphers, from the same family

Closed this issue · 1 comments

Background

As explained by Daniel J. Bernstein in this paper, ChaCha is a variant of Salsa20. Apparently (to be confirmed by an expert)

"ChaCha follows the same basic design principles as Salsa20, but I changed some of the details, most importantly to increase the amount of diffusion per round. "

Description

Salsa and Chacha should be considered different algorithms

I think we should rename Chacha. The algorithms were splitted in a previous version
