3DES对称加密算法（ABAP 语言实现版）

公司人事数据要求在系统间加密传输，而对接系统大部分是Java系统，要在不同的异构系统间能很好的加解密码，想到了标准的对称加密算法DES，因为是标准的算法，网络上存在大量公开用Java的DES算法，JAVA系统无需再写。但SAP里面没有找到DES加密的算法，所以只能在SAP里使用ABAP语言自己实现。在写的过程中要用到Bit位操作，ABAP里也是没有位移的原生操作，所以自己也只能像其他语言那样模拟的位操作，具体实现可以参考这里：ABAP语言实现 左移 <<、无符号右移 >>> 位移操作

本加密算法采用ABAP语言实现，加密出来的内容，能够传输到Java系统进行解密，反之亦然；另外本函数还实现了加密指纹验证，可以用来验证传输过来的内容是否被篡改过。
