scryptauth is a GO library for secure password handling using scrypt

It uses sha256_hmac(scrypt(user_password, salt), server_key) to protect against both dictionary attacks and DB leaks.

scryptauth additionally provides encode/decode routines using base64 to create strings for storing into a DB.

Choose your scrypt pw_cost factor (make bench helps you on this). Typical values used in production are between 11 and 14 which means a login will take at least 15 to 130ms, and your service will be able to handle only 66 and 8 logins per second with 100% load on a single CPU (keep that in mind!).
