Question

怎么用java实现HMAC-SHA1

Answer 1

以下代码为JAVABEAN，加密用
[PHP]
package test;

* you entered into with Sun.
*/

import java.security.*;
import javax.crypto.*;

/*
* This program demonstrates how to generate a secret-key object for
* HMAC-SHA1, and initialize an HMAC-SHA1 object with it.
*/

public class initMac {
public initMac() {
}

//定义加密算法
String Algorithm = "HmacSHA1";

public byte[] HmacSHA1(String post) throws Exception {
// Generate secret key for HMAC-SHA1
KeyGenerator kg = KeyGenerator.getInstance(Algorithm);
SecretKey sk = kg.generateKey();
// Get instance of Mac object implementing HMAC-SHA1, and
// initialize it with the above secret key
Mac mac = Mac.getInstance(Algorithm);
mac.init(sk);
byte[] result = mac.doFinal(post.getBytes());

return result;
}
}
[/PHP]
以下代码为调用上面JAVABEAN的部分

[PHP]package test;

import test.initMac;

/**

* <p>Description: </p>
