The Right Way To Hash a Password or Create an Encryption Key: PBKDF2, bcrypt and scrypt

In computing, we often need things to be fast, but sometimes we need to slow things down and create a problem that cannot be scaled onto parallel processors. One of these applications is in the hashing of a password. The fast hash crackers can process SHA-1 and SHA-256 hashes at rates that can be over 1 terahashes per second. That’s 1,000…
