How to use md5-like crypto to store and use user password?

Hi,
I've seen that you can easily configure xataface to use a table with fields for user name and password for authentification. Great. But, as far as I know, you should store password as clear text, and I dislike that.
Is there a way to use md5 or sha1 hash or something like to store the password, and use the result the same way?
Best regards,
