Introduction
Computer security is undeniably important, and as new vulnerabilities are discovered and
exploited, the perceived need for new security solutions grows. "Trusted computing"
initiatives propose to solve some of today s security problems through hardware changes
to the personal computer. Changing hardware design isn t inherently suspicious, but the
leading trusted computing proposals have a high cost: they provide security to users
while giving third parties the power to enforce policies on users computers against the
users wishes -- they let others pressure you to hand some control over your PC to
someone else. This is a "feature" ready-made for abuse by software authors who want to
anticompetitively choke off rival software.
It needn t be this way: a straightforward change to the plans of trusted computing vendors
could leave the security benefits intact while ensuring that a PC owner s

利用java實現文件的AES加密功能
This Java AES Crypt package contains the Java class es.vocali.util.AESCrypt, which provides file encryption and decryption using aescrypt file format.
Requirements
The Java AES Crypt package only works in Java 6, but can be easily adapted to Java 5 by replacing the call to NetworkInterface.getHardwareAddress() with something else.
In order to use 256 bit AES keys, you must download and install "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from http://java.sun.com/javase/downloads/index.jsp
