comment How to bring little changes in DES algorithm
@JeffFerland, A request: I'd prefer that moderators not migrate bad questions; bad questions should be closed with feedback to the question-asker about how to improve them so they can be re-opened, rather than migrated to some other site to deal with. Crypto.SE has extensive policies on "homework" questions in its meta site, and this question doesn't meet any of those standards.
