Android SHA加密實現

同前篇博文的MD5加密

只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 * @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();}}
