des加解密的算法，不错的字符串加密与解密(des encryption and decryption algorithms, a good string encryption and decryption)

说明：  DES加密算法，C++编写，有界面有录像，写的很详细的大项目(DES encryption algorithm, C++ written, there is a video interface, written in large projects in great detail)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

PHP5.2 5.3 5.4等 zend加密代码解密(PHP5.2 5.3 5.4 Zend encryption code decryption)

椭圆曲线密码算法及其应用论文，对椭圆曲线加解密算法实现具有很好参考价值(Elliptic curve cryptography algorithm and its application papers, the elliptic curve encryption and decryption algorithm to achieve a good reference value )

对于ECC 进行加密解密运算，这里主要是ECDSA的签名(For ECC encryption and decryption operations, where mainly ECDSA signature)

MD5算法描述（略）。 设计一个模拟的系统用户安全登录界面，采用MD5算法实现用户登录口令的安全认证。要求模拟界面至少具有用户口令文件的注册和用户登录时输入的口令是否正确的结果提示两个功能。 (MD5 algorithm description (abbreviated). The design of a simulation system security log user interface, using MD5 algorithm users log on password security authentication. Analog interface requirements at least a registered user password files and user login password is entered when the correct results suggest that the two functions.)

说明：  AES加密算法的加密部分，128位加密算法实现(AES encryption algorithm the encryption part, 128-bit encryption algorithms)

针对Logistic映射，实现数字图像迭代混沌加密算法()

vc++写的ElGamal加密系统，能够对简单的数字进行加密。(The ElGamal encryption systems, vc++ write simple digital encryption.)
