混合加密程序,RSA算法加密DES密钥,DES算法加密消息.很多通讯系统都是这样加密的...

MD5加密算法，有个 getMD5() 方法可以传入字符串并生成一个 MD5 码。-MD5 encryption algorithm, there" s getMD5 () method can pass a string and generate an MD5 code.

用来脱被upx加过壳的文件,包括被upxfix等修改过的文件,适用于几乎所有版本(不过特低的好像有些问题:( ) 欢迎指正!msn:phoenix8088@hotmail.com-UPX from being used to shell the documents have been added, including such upxfix revised document, applicable to almost all versions (particularly low, however it seems there are some problems: () please correct me!

是用的美国标准的DES加密算法用C++编写的可以完成以内的字符垢加密-the United States is using the DES encryption standard algorithm with C prepared to be completed within the characters scale encryption

密钥扩展的源代码-Key expansion of the source code

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

RSA公钥加密，用C实现，大家可以参考一下-RSA public key encryption, using C to achieve, we can refer to

sha1摘要算法 简单易懂 测试已通过 将文件进行散列加密处理-sha1 digest algorithm simple test has been passed to deal with file hash encryption

MD5加密算法源代码+DLL成品,这个更好,有完整的VC源码,更加强大,可以直接做成DLL文件进行调用.特爽,MD5就不用说了吧.-MD5 encryption algorithm source code DLL finished, the better, a complete source VC, more powerful, and can directly cause for calling DLL files. Special autumn, MD5 would not have said it.

应用背景基于java的自定义文件加压解压，拥有比普通压缩包密码更方便更保险的加密程度关键技术通过更改了文件数据写入顺序起到加密效果，如果不用相应的解压程序解压的话会使得文件无法读取

用VC做的一个画直线和曲线的程序。-VC do a painting line and curve procedure.
