This is a patch for GnuDIP's minidip server. It switches the password storage format from plain text to md5 hashes, so you can copy passwords from GnuDIP to MiniDIP and vice versa. Furthermore, this allows you to use arbitrary characters in your passwords without breaking the format of the config files. Use GnuDIP's encpass utility to encrypt passwords.
