MD5实现Token校验

 

A端执行getToken方法把TokenA和data传给B端,B端接收到A端的TokenA和data后,执行本地方法getToken获得TokenB,

比较TokenA和TokenB,相等则校验成功,getToken方法如下:

public static String getToken(String data){

 //key为密钥
private String key = "74c2d6cf-a9f0-4278-8cd8-b1ab11a5c79e";
String dataAndKey = data +"|"+ key;
String resultString = "";
try {
resultString = new String(dataAndKey);
MessageDigest md = MessageDigest.getInstance("MD5");
resultString = byteArrayToHexString(md.digest(resultString
.getBytes("UTF-8")));

} catch (Exception exception) {
}
return resultString;
}
