Did you post Acme Enc, as perlsameer?
Regardless, have you checked your web servers error log file to find out what is wrong with your script? Does it run from the command line without any problems? Have you looked at any of the posts in CGI Programming from the tutorials section of this site?
Read How do I post a question effectively? since you have, again, not given us much to go on (No example code, which you seem to be obfuscating despite the advice given in Acme Enc, no error messages, no information about your web server setup).
Try and make some effort in posting, and choosing the title you give your post Acme::Bleach and Acme::Enc are hardly descriptive titles.
