The two main traits of a hash are that . it should be one-way and. it should be cheap to compute. Obviouslty these requirements go against each other. So a compromise is made. WebDec 20, 2016 · The pepper is a 256-bit AES key. If an attacker doesn't get hands on this one there's no way they can recover the hashes and thus potentially the passwords. However as soon as you have exfiltrated the key, the additional AES encryption has just about 0 influence on the run-time required for brute-forcing a key.
