Memory hardness is the real defense against GPUs and ASICs. How argon2id, bcrypt, scrypt and PBKDF2 compare, how to tune them, and which one to actually pick.

MD5 and SHA-1 fall to a GPU in seconds because they are fast and often unsalted. Learn why slow KDFs like bcrypt and Argon2 resist — and what defenders should do.
