一个DES加密算法的实现-a DES encryption algorithm implementation

DES Crypt adapted from unix crypt for delphi.

常用的密码算法，如RSA，MD2，MD5等，还包括简单的例程，很久以前写着玩的-commonly used cryptographic algorithms, such as RSA, MD2, MD5, also includes a simple routine, a long time ago wrote a play

一个Java例子，包括加密、ftp-A Java examples, including encryption, ftp

这是一个C的源代码，用来实现基于身份的加密算法-This is a C source code, used for identity-based encryption algorithm

程序实现了大素数的判断和如果不是素数，则其可分解的最小的素数-program of large prime numbers and if the judgment is not prime, then decomposition of the smallest prime number

一些常用的方法，很不错的实例，可以拿来学习，很不错哟-Some commonly used method, it is a good example, can be used to study, very good yo

MD5算法的实现。MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.

VC实现的图像加密算法，采用Arnold变换，对于初涉信息安全的人员有一定参考价值-The algorithm of encrypted image completed in VC, applying the Arnold transform .It is valuable to people who will devote himself to infomation security
