基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

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. )

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

RSA公钥加密程序RSA公钥加密程序RSA公钥加密程序RSA公钥加密程序RSA公钥加密程序(RSA public key encryption program)

密码技术实验一经典密码学实验维多利亚密码加密解密(Password technological experiments classic cryptography experimental Victoria password encryption and decryption)

一个能直接运行的AES加密解密程序，用VC2010开发。(A run of AES encryption to decrypt application directly, use VC2010 development.)

playfair 加密算法的实现，用一个例子做了展示(realize playfair algorithm，use a sample to show the algorithm)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

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.)

本程序可以在 PE 文件的结尾增加一个新节，从而在已被“加密”的程序开始运行时，要求输入密码。(This procedure can be the end of the document in the PE to add a new section, which has been in the encryption process to start running when asked to enter a password.)
