Posted by: aaaa2004 Posted on: 2004-10-06 12:08 我在一本介绍java安全的书上看到一段计算消息摘要的程序,但是我不明白程序是如何以字符的形式显示消息摘要的,请各位大虾指教!!谢谢!! import java.security.*; public class DigestCalc{ public static void main(String args[ ]) throws Exception{ String x=args[0]; MessageDigest m=MessageDigest.getInstance("MD5"); m.update(x.getBytes( )); byte s[ ]=m.digest( ); String result=""; for (int i=0; i<s.length; i++){ result+=Integer.toHexString((0x000000ff & s[i]) | 0xffffff00).substring; } System.out.println(result); } } |
