Hi,<BR><BR>I am willing to implement a Challenge/Response authentication mechanism using ASP and SQL Server 7.0. I do not want to use the NTLM mechanism proposed by IIS, to be Netscape compliant.<BR><BR>Today, I have the JavaScript Routines (SHA1 and MD5) that will generate the response based on the Challenge (provided by the server) and the user login password.<BR><BR>Now, I need to have SQL Server compute the same encyphered response based on the challenge and the password stored in the database. How can I do that. Does anyone knows an extended stored procedure that computes MD5 or SHA1 hashes?
