The Rules Engine API does not provide a clear security mech

This article mainly discusses cryptography and digital signature, and how it is used in Java. The partner who is interested in cryptography is recommended to see Bruce Schneier's book: Applied Crypotography. There has been a great improvement in security in the release of jdk1.5, as well as direct support for RSA algorithms, and now we're going to solve the probl
