SHA加密算法是目前广为应用的重要加密方法之一。而SHA-1 生成 160 位的消息摘要，虽然执行更慢，却被认为更安全。明文消息的最大长度可达到 264 位。下面是网络上流传的SHA算法，我们自己调试了一下，已经通过。现把主函数和算法函数贴出来。-SHA encryption algorithm is an important widely used encryption methods. And SHA-1 generates the message digest 160, although more slowly, but think more secure. Explicit messages the maximum length could reach 264. The following is a network spread SHA algorithm, debugging a bit of our own has passed. Are the main functions and algorithms function posted.
