Hello, The RFC for introducing Argon2 as an alternative hashing algorithm for the password_* functions is now open. The RFC is available at https://wiki.php.net/rfc/argon2_password_hash.
Voting is open for 1 week, and will close on August 8th with a 50%+1 majority required to pass. If either of those need to be adjusted please let me know. Thanks! *Charles R. Portwood II*
