Enforcing minimum password length of 20 characters is a good feature. If
someone is trying to brute force your password, 20 characters is a *major*
obstacle. Five or six characters is not.

How many bits of useable key material does rmd160 provide?  80?

Does anyone know of GPL licenced implementation of SHA-256, SHA-384 or
SHA-512? SHA-256 should provide 128 bits of useable key material.
