MD5的用法之加密

简单应用:
 
public String md5(String toChapter) { 
 
        String str = ""; 
 
        try { 
 
            MessageDigest md = MessageDigest.getInstance("MD5"); 
 
            md.update(toChapter.getBytes()); 
 
            byte[] buf = md.digest(toChapter.getBytes()); 
 
            BigInteger bi = new BigInteger(buf); 
 
            str = bi.toString(36);// 36进制数的字符串形式 
 
        } catch (NoSuchAlgorithmException e) { 
            e.printStackTrace(); 
        } 
        return str; 
    } 
 
调用:
 
System.out.println(high.md5("-3i6yl6rk0wpuvopdqpal6y8v9")); 
System.out.println(high.md5("中文").equals(high.md5("中文")));
