这一个16位的CRC校验的源码，源码也已经很详细的注释过了

EXELOCK 1.83 EXE文件加密器的源代码-EXELOCK 1.83 EXE file encryption for the source code

包含几种高级加密算法,带Exe演示程序-contains several advanced encryption algorithm, with Exe Demonstration Program

DES Crypt adapted from unix crypt for delphi.

Converst a bit array into a single byte and vice versa

此为国外转载函数，可将任意字符转换为md5 16为字符加密形式，而且为不可逆转换。-reproduced here for foreign functions, arbitrary characters can be converted to 16 md5 encrypted form of characters, but also to irreversible change.

MD5加密，已经封装成一个C++类，只要调用该类就可方便使用-This C++ class serves as a wrapper for the Message Digest 5 code described in the Internet RFC 1321.

symbian 系统下面的des算法的实现方式-symbian system, the following des Algorithm approach

极好的加密程序，DES的接班人，源码是DEHLPHI的Pascal，编译后可直接运行-Excellent encryption, DES s successor, is DEHLPHI source of Pascal, the compiler can be run directly

OPT一次性动态口令验证算法。根据动态支持TOTP和HOTP验证。-A one-time dynamic password authentication algorithm OPT. According to dynamic support for TOTP and HOTP authentication.
