Dear CFRG,
we have prepared a new version of the Argon2 draft. Great thanks to our
reviewers, as the comments helped us to improve the text a lot. We also
provided a self-containing reference implementation in C in the appendix.
We have made our comments to the reviews at [1], but 95% of them are Fixed
or Added, and no comment has been left unresolved.
We would also like to thank Jeremiah Blocki for his helpful comments. In
particular, he suggested a new formula for the edge distribution to make
Argon2i more resistant to tradeoff attacks. We are very interested in such
research, and are looking forward to the third-party analysis (by us or
others) of the proposed constructions. If the new edge distribution
withstands public scrutiny, it would make sense to apply it in future
releases of Argon2i and Argon2id.
We are ready to answer any other questions and integrate more comments if
needed.
Best regards,
Alex, Daniel, Dmitry.

Abstract:<br>
This document describes the Argon2 memory-hard function for password<br>
hashing and proof-of-work applications. We provide an implementer-<br>
oriented description together with sample code and test vectors. The<br>
purpose is to simplify adoption of Argon2 for Internet protocols.<br>
