I am looking for an easy to use MD5 hashing function. Then I need to know what datatype to make the field in the DB that I am saving this value to.
I do NOT want Encryption because I want the value to be irreversible. This is for passwords to an admin section and I don't want people seeing the passwords if they look at the data in the DB.
Lastly, it's not necessary, but if there is also a way to perform the function about in SQL so I can write a quick update script w/o going through my code, that would be great!
