Hex介绍

[英][Hexadecimal](http://en.wikipedia.org/wiki/Hexadecimal) encoder and decoder.

This class was borrowed from Apache Commons Codec SVN repository (rev. 560660) with modifications to enable Hex conversion without a full dependency on Commons Codec. We didn't want to reinvent the wheel of great work they've done, but also didn't want to force every Shiro user to depend on the commons-codec.jar

[中][Hexadecimal](http://en.wikipedia.org/wiki/Hexadecimal)编码器和解码器。
这个类是从ApacheCommons编解码器SVN存储库（版本560660）中借用的，经过修改，可以在不完全依赖于Commons编解码器的情况下实现十六进制转换。我们不想重新发明他们所做的伟大工作，但也不想强迫每个Shiro用户依赖commons编解码器。罐子
