用python/java实现hmacmd5加密的一个示例

hmacmd5(using python/java)

1. python实现hmacmd5的示例

# coding: utf-8

import hmac
import hashlib

ekey = 'samplekey'
to_enc = 'sampledata'

enc_res = hmac.new(ekey, to_enc, hashlib.md5).hexdigest()
print enc_res

2.java实现hmacmd5加密的示例

import java.security.MessageDigest;
import javax.crypto.KeyGenerator;
import javax.crypto.Mac;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;


/** * 基础加密组件 * @version 1.0 */
public class Coder {
    /** * MAC算法可选以下多种算法 * * <pre> * HmacMD5 * HmacSHA1 * HmacSHA256 * HmacSHA384 * HmacSHA512 * </pre> */
    public static final String KEY_MAC = "HmacMD5";

    /** * HMAC加密 * * @param data * @param key * @return * @throws Exception */
    public static byte[] encryptHMAC(byte[] data, String key) throws Exception {

        SecretKey secretKey = new SecretKeySpec(key.getBytes(), KEY_MAC);
        Mac mac = Mac.getInstance(secretKey.getAlgorithm());
        mac.init(secretKey);

        return mac.doFinal(data);

    }

    /*byte数组转换为HexString*/
    public static String byteArrayToHexString(byte[] b) {
       StringBuffer sb = new StringBuffer(b.length * 2);
       for (int i = 0; i < b.length; i++) {
         int v = b[i] & 0xff;
         if (v < 16) {
           sb.append('0');
         }
         sb.append(Integer.toHexString(v));
       }
       return sb.toString();
     }

    public static void main(String[] args)throws Exception{
        String inputStr = "{\"somek\":\"somev\"}";
        byte[] inputData = inputStr.getBytes();
        String key = "somekey";
        System.out.println(Coder.byteArrayToHexString(Coder.encryptHMAC(inputData, key)));
    }
}
