Android SHA加密實作

同前篇博文的MD5加密

隻要把加密文本轉換為String就好了

package com.tencent.utils;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
/**
 * 對外提供getSHA(String str)方法

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();
}
}
