bcrypt is a hashing algorithm which is scalable with hardware (via a configurable number of rounds). its slowness and multiple rounds ensures that an attacker must deploy massive funds and hardware to be able to crack your passwords. add to that perpassword salts ( bcrypt requires salts) and you can be sure that an

one standout option in php is bcrypt. bcrypt is an adaptive hash function based on the blowfish symmetric block cipher cryptographic algorithm. it uses a key factor (or work factor) which adjusts the cost of hashing, which is probably bcrypt's most notable feature. the ability to increase the cost (time and

hash your passwords with something other than md (bcrypt or sha). don't invent your own algorithm. you will fail. use a unique, random salt for each password and store both the salt and hash. salt does not have to be secret. each salt has to be unique so the hashes are unique. algorithms won't fix bad passwords.
