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;
