.net密码术 其中包括了对称加密、非对称加密、数字签名、散列算法等。(. Net cryptography including symmetric encryption, asymmetric encryption, digital signatures, hashing algorithm.)

crc 详尽的源码 值得参考 具体要求可根据自己需要设置-CRC detailed reference source should be specific requirements may need to set up according to their own

有关欧几里德的扩展算法，非常实用，经测试好用- The expansion of the Euclidean algorithm, is very practical, easy to use as test

这只是标准DES算法的例子,必须在WINDOWS环境下编译.(This is just the standard DES algorithm, which must be compiled in the WINDOWS environment.)

快速MD5碰撞生成器，王小云改进版。这个生成器根据“构造前缀碰撞法”可以生成两个不同的文件，而这两文件的md5 sum却是一样的。 MD5 Collision Generator(win32 .exe) MD5 Collision Generator(source) -Fast MD5 collision generator, Xiaoyun Wang, improved version. The generator according to "construct the prefix collision" system can generate two different files, while the md5 sum of these two documents is the same.

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. )

使用C编写的DES, DESX, DES3(三层DES) 的加密算法, 本程序演示如何在Delphi中进行调用C编写的算法 DES 密匙长度 8 DESX 密匙长度 16 DES3 密匙长度 24 (加密强度高了很多)-prepared by the use of C DES, DESX, DES3 (triple DES) encryption algorithm, this program shows how the Delphi C called for the preparation of the DES algorithm key length 8 DESX key length of 16 key length DES3 24 (encryption a lot higher intensity)
