This code is designed particulary to encrypt all or most stored procs in your database
please remember to backup your procs first before encrypting them. this is intended to be used before you release your code to your client.
Should you have syntax error, in my experience this is caused by the browsers markup in the sql script code box. try copying and pasting this code into sql query, for some reason if you copy the code from directly below things are ok.

i imagine my low ratings on this code is specifically due to the syntax errors got from the markup, if not please comment.
