### Description OpenSSL now provides argon2 algorythms See: https://www.openssl.org/docs/manmaster/man7/EVP_KDF-ARGON2.html It will be nice to be able to use argon2 password hash methods from OpenSSL extension when PHP is build without libargon2 and without libsodium Doable thanks to `php_password_algo_register` as already done in sodium Open for discussion Ping @bukka
