认证加密算法php hash_hmac和java hmacSha1的问题

public class Test{

public static void main(String[] args) throws Exception {

String postString = "abc";

String signature = ByteToHex(genHMAC(postString, "310A54B3C9C12920E1582E016F15DD441ACE8553769E8991")).toUpperCase();

}

/**

* 使用 HMAC-SHA1 签名方法对data进行签名

*

* @param data

*/

public static byte[] genHMAC(String data, String key) {

byte[] result = null;

try {

//根据给定的字节数组构造一个密钥,第二参数指定一个密钥算法的名称

SecretKeySpec signinKey = new SecretKeySpec(hexString2Bytes(key), "HmacSHA1");

//生成一个指定 Mac 算法 的 Mac 对象

Mac mac = Mac.getInstance("HmacSHA1");

}

public static byte[] hexString2Bytes(String src) {

int l = src.length() / 2;

byte[] ret = new byte[l];

for (int i = 0; i < l; i++) {

ret[i] = (byte) Integer

.valueOf(src.substring(i * 2, i * 2 + 2), 16).byteValue();

}

}

// btye转换hex函数

public static String ByteToHex(byte[] byteArray) {

StringBuffer StrBuff = new StringBuffer();

for (int i = 0; i < byteArray.length; i++) {

Integer.toHexString(0xFF & byteArray[i]));

} else {

StrBuff.append(Integer.toHexString(0xFF & byteArray[i]));

}

}

return StrBuff.toString();

}

}

方法一:

$str = "abc";

$key = "310A54B3C9C12920E1582E016F15DD441ACE8553769E8991";

$decodedKey = pack("H*", $key); //十六进制转成字符串

$hash = bin2hex(hash_hmac("sha1", $str, $decodedKey, true));

  

方法二:

//字节数组转化为String类型的数据

function toStr($bytes) {

$str = '';

foreach($bytes as $ch) {

$str .= chr($ch);

}

return $str;

}

//字符串转十六进制

function String2Hex($string){

$hex='';

for ($i=0; $i < strlen($string); $i++){

$hex .= dechex(ord($string[$i]));

}

return $hex;

}

//十六进制转字符串

function Hex2String($hex){

$string='';

for ($i=0; $i < strlen($hex)-1; $i+=2){

$string .= chr(hexdec($hex[$i].$hex[$i+1]));

}

return $string;

}

$str = "abc";

$key = "310A54B3C9C12920E1582E016F15DD441ACE8553769E8991";

$decodedKey = pack("H*", $key); //十六进制转字符串

$hash = hash_hmac("sha1", $str, $decodedKey, true);
//字符串转字节数组,即ascii数组

$hashs = str_split($hash);

foreach ($hashs as $index => $value) {

if (ord($value) > 128) {

$hashs[$index] = ord($value) - 128 * 2;

} else {

$hashs[$index] = ord($value);

}

}

$signature = String2Hex(toStr($hashs));

echo $signature;
