MD5 & CRYPT_STD_DES Question

I've got a fairly standard user dbase table which contains a password field. On the server all passwords have been encrypted with the CRYPT_STD_DES algorithm before being inserted into the dbase. However, Passwords are presently submitted from the login form in plain text. I want to make the system more robust by encrypting passwords on the client side using the javascript MD5 class. Is there any way I can make this compatible with the existing passwords which are encrypted with the DES 2 salt algorithm without writing some sort of change password stuff? Does anyone know of a Javascript implementation of the CRYPT_STD_DES algorithm. Thanks, webmonkey _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
