php加密javahmac sha1
最近遇到hmac_sha1跨语言加密的问题，只提供给了java加密文件，没提供php的，我用php hmac_sha1内置函数,得到的sig加密结果不同，欢迎高手帮忙提供相对应的php代码，提供的java类如下
欢迎加QQ: 847036019
public abstract class Coder {
public static final String KEY_SHA = "SHA";
public static final String KEY_MD5 = "MD5";
public static final char hexDigits[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'a', 'b', 'c', 'd', 'e', 'f' };
public static final String KEY_MAC = "HmacSHA1";
public static byte[] decryptBASE64(String key) throws Exception {
return (new BASE64Decoder()).decodeBuffer(key);
}
/**
* 初始化HMAC密钥
*/
public static String initMacKey() throws Exception {
KeyGenerator keyGenerator = KeyGenerator.getInstance(KEY_MAC);
<code> SecretKey secretKey = keyGenerator.generateKey(); return encryptBASE64(secretKey.getEncoded()); } /** * HMAC加密 */ public static byte[] encryptHMAC(byte[] data, String key) throws Exception { SecretKey secretKey = new SecretKeySpec(decryptBASE64(key), KEY_MAC); Mac mac = Mac.getInstance(secretKey.getAlgorithm()); mac.init(secretKey); return mac.doFinal(data); } public static void main(String[] args) { try { String param = ''; String appkey = ''; byte[] bytes = Coder.encryptHMAC((param).getBytes("utf-8"), appkey);//['-115','-101','97','-26','-80','-109','-92','33','-6','71','-122','-64','-17','-29','-101','-53','88','-93','-22','-104'] String sig = new BigInteger(bytes).toString();//-653068794747578802236590292838260814592085857640 System.out.println("sig:" + sig); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } }} java sig得出来的结果为 -653068794747578802236590292838260814592085857640</code>php我用相对应的加密即php自带函数
$signature = mhash(MHASH_SHA1,$sigstr,base64_decode($appkey));
$hash = str_split($signature);
foreach ($hash as $index=>$value) {
if (ord($value)>128) {
$hash[$index] = ord($value)-128*2;
} else {
$hash[$index] = ord($value);
}
}
php得到的ascii数组为$array('-115','-101','97','-26','-80','-109','-92','33','-6','71','-122','-64','-17','-29','-101','-53','88','-93','-22','-104');
请问该php如何处理得到下面的值
-653068794747578802236590292838260814592085857640
java用的是new BigInteger(bytes).toString();php该如何处理
