  • 在 c + + 中实现 RC4 算法
    首先,RC4算法生成一个“状态”,这开始为包含在订单值0-255的数组。然后该算法通过阵列迭代和周围交换的元素,基于所述键值。原始密钥然后可被丢弃,因为RC4只使用状态来创建一个伪随机密钥流,由算法选择的元素和吐出出来。密钥流的所述状态单靠额外的好处是,原来的密钥并不需要被保存在内存中。算法初始化状态。执行密钥调度算法(KSA)上的状态下,根据所输入的键(然后其可以被丢弃)。在算法选择(现炒)的状态,并将其输出作为密钥流元素。

  • Base64 算法(Author 蒋柏良 Jerry Jiang)
    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
