IDEA加密算法(PGP中使用的加密算法），对想研究pgp加密的人有没莫大帮助-IDEA encryption algorithm (PGP encryption algorithm used), and would like to study people pgp encryption has not much help to

多数程序设计语言处理整数的能力是有限的，如C语言中，int类型数据范围是-32767----32767。实际问题的处理过程中往往涉及大整数的运算，如RSA加密算法要求至少64bit的整数，本程序是设计算法实现大整数的加减运算。-majority programming language processing is integral to the limited capacity, such as C language, int data type is the scope-32767---- 32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, the procedure is designed algorithm large integer addition and subtraction operations.

生成程序序列号在程序加密方面几好用-sequence generation process, the procedure uses encryption several areas

C语言环境下的AES加密算法，支持128位的AES加密。-C language environment AES encryption algorithm, support 128-bit AES encryption.

c++的MD5类，简单好用，只需要包含进去，就能方便使用-c++ the MD5 class, easy-to-use, only need to include, we can facilitate the use of

带密钥的md5算法库md5lib.h共有下列函数： char* MDString (char *) /*输入任意一个字符串，经过md5算法处理后，返回结果：一个定长（32个字符） 字符串 */ char* MDFile (char *) /*输入任意一个文件名，文件内容经过md5算法处理后，返回结果：一个定长 （32个字符）字符串 */ char* hmac_md5(char* text, char* key) /*输入任意一个字符串text,和一个用做密钥的字符串key,经过hmac_md5算法处 理，返回处理结果：一个定长字符串（32个字符）*/ 具体使用方法可参考例子sample.c,其运行结果在本文后面。-Md5 algorithm with a key repository md5lib.h total of the following functions: char* MDString (char*) /* enter any one string, after md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* MDFile (char*) /* enter any of the file name, file contents through the md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* hmac_md5 (char* text, char* key) /* input a string of arbitrary text, and a string key used as key, after hmac_md5 algorithm processing, return processing results: a fixed-length string (32 characters)*/specific examples of the use of methods can be found sample.c, the results

S盒的线性逼近表的运算,可在程序里面修改数值,这是一本密码学的书籍上的题目的运算程序-S-box linear approximation table calculations, which can be modified numerical procedure, which is a cryptography book on the topic of computing procedures

twocrypt(2c)是一个 PoC工具，用于超狂妄者。它把两个文件加密成一个。不同的口令可以用于解译不同的变量。输出不能从单个加密文件中识别出来，并且这个工具使用一种合法的算法，这种算法本身并不意味着要隐藏任何信息。-twocrypt (2c) is a PoC tool, uses in the ultra arrogance. It encrypts two documents. The different password may use in the solution to translate the different variable. The output cannot from individually encrypt in the document to distinguish, and this tool uses one legitimate algorithm, this algorithm itself certainly did not mean must hide any information.
