现在很多J2EE应用都采用一个license文件来授权系统的使用，特别是在系统购买的早期，会提供有限制的license文件对系统进行限制，比如试用版有譬如IP、日期、最大用户数量的限制等。 而License文件中的Base64或BEA公司现在是WebLo

说明：  基于matlab实现AES加解密和基于AES的cmac(AES encryption and decryption based on MATLAB and CMAC based on AES)

在实现AES基础上，用C编写CMAC算法并调试通过。输入数据进行CMAC验证。(In the realization of AES based on the CMAC algorithm written in C and debugging. CMAC input data validation)

crc32加密算法，希望对大家有帮助，多多支持-CRC32

DEC算法的实现，很特别-DEC algorithm to achieve something special

密码安全方面的PGP资料,很有用的!是学习密码学的好东西@-PGP password security information, very useful! Is a good thing to learn cryptography @

DES in verilog codes

将小于32位的码字用1011编程循环冗余码！ 并且可以检验已编好的循环冗余码是否正确！-Will be less than 32-bit code word to use Cyclic Redundancy Code 1011 programming! And can be tested has been a good cyclic redundancy code is correct!

隐藏软件-hidden software !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
