hi, there is no way to decrypt a MD5 checksum. Even though you can't decrypt a MD5 checksum, you can still use it to validate password entered by a user during a login process up against a checksum stored in a database. //Pseduo code IF (MD5("entered password") == stored_md5_sum) THEN USER LOGIN SUCCESED. SQL Query SELECT 1 FROM users WHERE username="john" AND password=MD5("secret password"); bye Mohammed --- gpldeveloper <gpldeveloper@yahoo.com> wrote: > Dear Friends, > I have a little problem ragarding conversion md5 > encripted data. > please giude me how to decript it. > my problem is follows, > > in my application password is stored in mysql > database by using md5 > function. > like, > $password = md5($password); > > > My requirement is to get original data from database > where encripted > string is storded.. > > is it possible to decript md5 data, > if yes guide me how it will done > > Thanks in Advanace > > > > __________________________________ Do you Yahoo!?
