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

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 with 512-bit packet to process the input information, and each group was again divided into 16 32-seat group, after a series of processing, the algorithm" s output consists of four 32-bit group composed of these four 32-bit Cascade Group will generate a 128-bit hash value.
