Base64 encoding and decoding, MD5 encryption source DEMO

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

文本加密，利用异或操作对指定文件进行加密，加密密码由用户输入-Text encryption, the use of XOR operations on the specified file is encrypted, encryption, password from user input

md5是常用的加密算法，但是在vc中没有系统的类可以用。本程序完成了md5类，使用简单。不是国内网上流传的类。-md5 is a commonly used encryption algorithm, but in vc no class system can be used. This procedure was completed md5 categories, using a simple. Rather than domestic circulating online class.
