Subject Re: [PATCH] encryption support in
Date Fri, 09 Feb 2001 22:46:54 GMT
Hi Mathias,

Your patch is interesting and is resolving a clear problem.

On the other side, I would propose you create another module ( let's say
CryptedRealm ? ). SimpleRealm should remain "simple".

What's missing is the ability to store the passwords ( how do you plan to
encrypt ? a passwd tool ? ). Maybe we can add an admin page to manage
users and passwords, and then we'll have all the elements for using
crypted passwords.

I would also propose to include this new module in 3.3.
