Argon2

This is a fork of the reference C implementation of Argon2, the password-hashing function that won the Password Hashing Competition (PHC).

About Argon2u

In addition to the official three variants (Argon2i, Argon2d, and Argon2id), this fork also implements a fourth variant, Argon2u. It operates similarly to Argon2id, in that it is a hybrid of Argon2i and Argon2d. Where Argon2id uses Argon2i's algorithm for the first two processed segments, Argon2u does this for the first three.

argon2's Issues

Modifications for asm-js/wasm no longer needed

According to this the reference implementation now works in WebAssembly without any changes. As such, we can revert the changes made in 1201c2e.

Process here would be to do the revert on a branch, see if urbit/argon2-wasm still builds and runs fine, merge the branch if it does, then update urbit/argon2-wasm to pull in the latest commit of this repo.

In doing so, we might want to try and pull in recent changes to the reference implementation.
