Security (java.security.*)

One of the key points in Java. There are several levels of security in Java: language level, VM level, API level, browser level, etc. Lots of improvements have been made in the JDK1.2 over the JDK1.1. Not only applets, but also applications can be subject to a security policy file that lists a set of permissions to a particular resource and a number of various signers and locations. There are also API's for authentication, data encryption and decryption. Check out the Cryptography category for more information.
