encryptedPassword field on the database

Hello everyone,

Is there anyone know how to encrypt/decrypt the password for encrypedPassword using the standard authenticate method (such as perl module or XMPP plugin for .Net or VBscript, etc…) I have been looking around but could find way to do this. I can use the perl module Net::Jabber to authenticate from the frontend through jabber but I want to have the authenticate using the backend database rather than using the jabber module. But if you know there is a way to authenticate from the frontend with ASP, please let me know too.
