In plaats van het password kan ook de hash van het wachtwoord worden encrypt.

In werkelijkheid wordt het wachtwoord NIET leesbaar bewaard.

In het geval de database wordt gejat, moet eerst de encrypted hash worden decrypt alvorens de hash zelf kan worden gekraakt.

De $SQL_encrypt_key variable moet op een veilige plek worden bewaard. De meningen verschillen over waar die veilige plek dan wel is.
