hmacmd5(using python/java)

1. python实现hmacmd5的示例

# coding: utf-8import hmacimport hashlibekey = '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)));    }}
