Android： JAVA和C# 3DES加密解密
最近 一个项目.net 要调用JAVA的WEB
SERVICE，数据采用3DES加密，涉及到两种语言3DES一致性的问题，
下面分享一下，
这里的KEY采用Base64编码，便用分发，因为Java的Byte范围为-128至127，c#的Byte范围是0-255
核心是确定Mode和Padding，关于这两个的意思可以搜索3DES算法相关文章
一个是C#采用CBC
Mode，PKCS7 Padding,Java采用CBC Mode，PKCS5Padding Padding,
另一个是C#采用ECB
Mode，PKCS7 Padding,Java采用ECB Mode，PKCS5Padding
Padding,
Java的ECB模式不需要IV
对字符加密时，双方采用的都是UTF-8编码
下面是C#代码
