I'm not sure that I understand what is being asked here:
If you would like to see an encrypted version of any value you can output it with php like this:
<?php print(sha1("the value to show as encrypted")); ?>
There are other methods of hashing a value that do not rely on sha1. It will create a hash value for you, but how safe it is depends on who you ask. I think in general it would be fine for most instances, but there are others out there that might produce a larger harder to crack hash. You should be able to find out more about them by searching the php site.
