Digital signatures are based upon public-key cryptography. You cannot recover a private key given a public key -- that's the whole point of public-key crypto. Such algorithms are based on one-way functions: things that are easy to do but hard to reverse. I don't have ready links on the subject, but I'd start with Wikipedia and roll from there. There are also several books on the subject. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.7 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
