数字签名加密算法的两座大厦先后倒塌―MD5和SHA

大数运算库miracl。有了miracl这样的函数库，你可以直接调用函数，来实现你要的公钥密码学的某个功能。-Treasury computing large numbers miracl. With miracl this library, you can directly call the function, to realize that you ask for a public-key cryptography functions.

Openssl的SSL证书认证程序，也是用VC写的。已通过测试。-Openssl SSL certificate authentication procedures, as well as with VC writes. Have passed the tests.

Cryptography application implement in PIC

Ｃ的原代码，可以参考的．用一定的下在价值-the original C code can reference. With a certain value in the next

密码学的数字签名算法 来自国外教材-Cryptography Digital Signature Algorithm materials from abroad

各种反分析软件的手法,包括(反Dede,反单步跟踪,反SoftICE,Ollydbg,反静态分析,以及程序自身的CRC32效验等,对于初学者有很大的帮助.-Analysis of various anti-software approach, including the (Anti-Dede, anti-single-step tracking, anti-SoftICE, Ollydbg, anti-static analysis, as well as procedures for their own well-tested, such as CRC32, for beginners and has a great help.

使用的是BCB5开发的一个简单的3DES的DEMO，对文件采用的是密文挪用来处理短块。-Using BCB5 developed a simple 3DES of DEMO, the document is used ciphertext diverted to deal with the short block.

一个完全使用java编写的加密通用算法包，含des,des3,rsa等很多加密算法源码- Completely uses the java compilation the encryption general algorithm package, contains des, des3, rsa and so on very many encryptions calculates the law origin code

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).
