问题描述
以下是我用于创建 HMAC 哈希的 nodejs 函数 -
function hash() {
key = "hello";
msg = "Hello";
var hmac = crypto.createHmac('sha256',key);
hmac.update(msg,'utf8');
var digest = hmac.digest();
console.log('---hash =======>' + digest);
return digest;
}
function hmacHex(key,msg) {
var hmac = crypto.createHmac('sha256','utf8');
var digest = hmac.digest('hex');
console.log('---hmacHex ====>' + digest);
return digest;
}
var res = hash();
hmacHex("hello",res);
OUTPUT FROM hash() => }/�(K=�����('�Zt�h�\D�Z��@ywڦ�
OUTPUT FROM hmaxHex() => 692a18bd347476d28300e579794ba799cda80625191ef71783fce95692c2b6f9
class Signature{
public function hash()
{
$key = "hello";
$msg = "Hello";
$hash = hash_hmac('sha256',utf8_encode($msg),$key,true);
error_log('---hash ===>'.$hash);
return $hash;
}
public function hmacHex($msg)
{
$key = "hello";
$hash = hash_hmac('sha256',false);
error_log('---hmacHex ===>' . $hash);
return $hash;
}
}
$obj = new Signature();
$res = $obj->hash();
$obj->hmacHex($res);
OUTPUT FROM hash() => }/?(K=?????('?Zt?h?\D?Z??@ywڦ?
OUTPUT FROM hmacHex => d920859abc579a070f2f8177e71d8431955784c8ed1d596b3364871ba35b5951
从输出中可以明显看出,在 nodejs 中我得到了替换字符,而在 PHP 中它显示为一个问号。
我正在尝试从我的 PHP 代码生成完全相同的输出,以便在重新散列输出时应该是相同的。
解决方法
我会更新我的答案以反映您的代码更改。感谢@Topaco 解决了这个问题。
php
class Signature {
public function hash()
{
$key = "hello";
$msg = "Hello";
$hash = hash_hmac('sha256',$msg,$key,true);
error_log('---hash ===>'.$hash);
return $hash;
}
public function hmacHex($msg)
{
$key = "hello";
$hash = hash_hmac('sha256',false);
error_log('---hmacHex ===>' . $hash);
return $hash;
}
}
$obj = new Signature();
$res = $obj->hash();
$obj->hmacHex($res);
节点
class Signature {
public function hash()
{
$key = "hello";
$msg = "Hello";
$hash = hash_hmac('sha256',false);
error_log('---hmacHex ===>' . $hash);
return $hash;
}
}
$obj = new Signature();
$res = $obj->hash();
$obj->hmacHex($res);
php 输出:
---hash ===>}/(K=('Zth\DZ@ywڦ
---hmacHex ===>692a18bd347476d28300e579794ba799cda80625191ef71783fce95692c2b6f9
Node.js 输出:
---hash =======>}/�(K=�����('�Zt�h�\D�Z��@ywڦ�
---hmacHex ====>692a18bd347476d28300e579794ba799cda80625191ef71783fce95692c2b6f9
