Base64 加密算法（Author 蒋柏良 Jerry Jiang)-* * DESCRIPTION * Base64 processes input in 24bit chunks by converting each chunk into 4 * bytes of output. It does so by splitting input into four 6bit groups and * using these as indexes in the following substitution table- * const char base64_map[] = * "ABCDEFGHIJKLMNOPQRSTUVWXYZ" * "abcdefghijklmnopqrstuvwxyz" * "0123456789+/" * If an input is not a multiple of 3 bytes, it s padded with zeros. In * this case the output bytes that consist entirely of the pad data are * replaced with = . * * Example * An input of 0x00 0x45 0xF2 is equivalent to 00000000 01000101 11110010 * bit sequence, which s then split into 000000 000100 010111 110010 * and these are substituted to produce the following base64 encoding * A E X y * * RETURN VALUE * b64_length() should return output length for the input of len bytes. * b64_encode() should encode len bytes from src int

基于VC6的MD5加密源码,短小精干，利于交流学习。-MD5 encryption source code, the short crack, and conducive to the exchange of learning.

.rar中包括两个文件MD5.cpp和MD5.h，在MD5的基础上改进让其支持Unicode的宽字符，可以对CString进行32位的加密，使用vs2010进行测试过，在解决方案“头文件”“源文件”分别使用添加“已有项”，将.h和.cpp文件加入工程，可能会有两三个警告，但不影响程序运行

这是一个RSA的简单实现算法,用的是C++语言实现的.-This is a simple realization of the RSA algorithm is used in the C language.
