3 years ago Meant to mention: I've left the tests in for now so you can see it all in one place, but I'd be happy to rewrite them with tape in https://github.com/sodium-friends/sodium-test and remove them from here before merging if you'd like to merge this.

Implements hchacha20 and secretstream_xchacha20poly1305 and their tests (https://github.com/jedisct1/libsodium/blob/master/test/default/xchacha20.c, https://github.com/jedisct1/libsodium/blob/master/test/default/secretstream_xchacha20poly1305.c).
It passes the C tests, and I've encrypted files with this and then decrypted them with Rust's sodiumoxide wrapper, but more real world testing may be warranted. This supersedes #55.
