Android SHA1加密实现

同前篇博文的MD5加密

只要把加密文本转换为String就好了

 package com.tencent.utils;

 import java.security.MessageDigest;
 import java.security.NoSuchAlgorithmException;
 /**
  * 对外提供getSHA(String str)方法
  * @author randyjia
  *
  */
 public class SHA {
     public static String getSHA(String val) throws NoSuchAlgorithmException{
         MessageDigest md5 = MessageDigest.getInstance("SHA-1");
         md5.update(val.getBytes());
         byte[] m = md5.digest();//加密
         return getString(m);
 }

     private static String getString(byte[] b){
         StringBuffer sb = new StringBuffer();
          for(int i = 0; i < b.length; i ++){
           sb.append(b[i]);
          }
          return sb.toString();
 }
 }
