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)

Paillier加密算法的实现。产生512位大数，进行大数运算。1、产生密钥2、加密、3、解密。(Paillier encryption algorithm implementation. Produce 512 Tarsus, Tarsus operation performed. 1, 2 generates a key, encrypts, 3, decryption.)

加密文件夹,十分好用 使用visual basic环境编程(lock file)

c++ 写的加密算法，可以加密解密，采用的算法是比较长用的(c write the encryption algorithm, encryption can be decrypted using the algorithm is relatively long with the)

古典密码中的仿射密码的加密和解密用C语言来实现。(Classical affine password encryption and decryption using C language to achieve.)

说明：  用visual c++ 写的des加密算法演示 (with visual c write des encryption algorithm demo)

说明：  编制程序，将输入的一行字符以加密的形式输出，然后将其解密，解密的字符串序列与输入的正文相比较，吻合时输出解密的正文，否则解密失败。 加密时，将每个字符的ascii码依次反复加上“4962873”中的数字，并在32（‘’）~122（‘z’）之间作模运算。解密与加密的顺序相反。例如输入正文“the result of 3 and 2 is not 8” 结果为： (Programming, the input line character output in an encrypted form, and then decrypted, the decrypted text sequence of characters compared with the input, output to decrypt the body of the agreement, otherwise the decryption failed. Encryption, ascii code of each character in turn repeatedly with &quot 4962873&quot in the figures, and 32 (' ' )~ 122 (' z' ) as a model between the operations. Decryption and encryption in reverse order. For example, enter the text &quot the result of 3 and 2 is not 8&quot results:)

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。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。下面是关于如何实现DES算法的语言性描述：(DES ( Data Encryption Standard ) algorithm, in 1977 the U.S. government s official permission , is a 56 -bit key to encrypt 64 data . 56 keys of the DES algorithm scenery is not , and often with Des encryption expressly decipher reported , but look at the old standard encryption algorithm is always useful , but the DES algorithm has been widely used in a some occasions , she still plays a waste heat . (such as : UNIX password algorithm is DES algorithm -based ) . To modify the Triple DES is also resistant to cracking . The following is a description language on how to achieve the DES algorithm : )

这是一个静态的md4算法加密，是在vc++的环境中执行，c语言编写；(This is a static md4 encryption algorithm is the vc environment implementation, c languages;)

加解密算法的实现，内部包含有多个加解密算法的实现，(Encryption and decryption algorithm, contains a number of internal encryption algorithm,)
