使用具有PHP的PEM文件加密数据购买

发布于 2025-01-24 16:14:23 字数 2251 浏览 2 评论 0原文

我有p12文件，然后将其转换为两个pem文件一个是pk文件，一个是私钥文件：

newfile.key.pem..pem content：

 localKeyID: 20 16 8C 58 E4 DD BC 0D 99 6D A3 DF A5 D1 65 C9 D2 DE 49 15 
subject=/C=PL/ST=Silesia/L=Katowice/O=GAZT/CN=CommonName

-----BEGIN PRIVATE KEY-----
MIGEAgXXXXXXXXXXXXXXPXfA4zjpFRaOUNWUBNuU
-----END PRIVATE KEY-----

newfile.crt.pem content作为公钥：

-----END CERTIFICATE-----

PHP代码：

// STEP 1: Encryption with Public Key (you will need Private Key to decrypt - see step2).
$PK="";

$fp=fopen ("newfile.crt.pem","r");
$pub_key=fread ($fp,8192);
fclose($fp);
$PK=openssl_get_publickey($pub_key);
$pub_key = "";
$string="Some Important Data";

if (!$PK) {
    echo "Cannot get public key";
}

$finaltext="";

openssl_public_encrypt($string, $finaltext, $PK);

 
if (!empty($finaltext)) {
    
    openssl_free_key($PK);
    
    echo "Encryption OK!";
    
  echo base64_encode($finaltext); 
    
}else{
    
    echo "Cannot Encrypt";
    
}

加密是给我加密的，

但是没有回声输出？

//STEP 2: Decription (Using Private Key)

$fp=fopen ("newfile.key.pem","r");

$priv_key2=fread ($fp,8192);

fclose($fp);

$priv_key2 = "";
$PK2=openssl_get_privatekey($priv_key2);

$Crypted=openssl_private_decrypt($finaltext,$Decrypted,$PK2);

if (!$Crypted) {
    echo "not decrypt";
    
}else{
    
    echo "Decrypted Data: " . $Decrypted;
    
}

实现它的正确方法是什么？因为我需要它来加密QR码中的TLV值？

我正在处理PHP 8.1 Cloud共享服务器。

原文

I have P12 file and I convert it to two PEM files one is PK file and one is Private key file:

newfile.key.pem content:

 localKeyID: 20 16 8C 58 E4 DD BC 0D 99 6D A3 DF A5 D1 65 C9 D2 DE 49 15

-----BEGIN PRIVATE KEY-----
MIGEAgXXXXXXXXXXXXXXPXfA4zjpFRaOUNWUBNuU
-----END PRIVATE KEY-----

newfile.crt.pem content as public key:

    localKeyID: 20 16 8C 58 E4 DD BC 0D 99 6D A3 DF A5 D1 65 C9 D2 DE 49 15

-----END CERTIFICATE-----

PHP Code:

// STEP 1: Encryption with Public Key (you will need Private Key to decrypt - see step2).
$PK="";

$fp=fopen ("newfile.crt.pem","r");
$pub_key=fread ($fp,8192);
fclose($fp);
$PK=openssl_get_publickey($pub_key);
$pub_key = "";
$string="Some Important Data";

if (!$PK) {
    echo "Cannot get public key";
}

$finaltext="";

openssl_public_encrypt($string, $finaltext, $PK);

 
if (!empty($finaltext)) {
    
    openssl_free_key($PK);
    
    echo "Encryption OK!";
    
  echo base64_encode($finaltext); 
    
}else{
    
    echo "Cannot Encrypt";
    
}

The encrypted is give me Encryption OK

but there is no echo output?

//STEP 2: Decription (Using Private Key)

$fp=fopen ("newfile.key.pem","r");

$priv_key2=fread ($fp,8192);

fclose($fp);

$priv_key2 = "";
$PK2=openssl_get_privatekey($priv_key2);

$Crypted=openssl_private_decrypt($finaltext,$Decrypted,$PK2);

if (!$Crypted) {
    echo "not decrypt";
    
}else{
    
    echo "Decrypted Data: " . $Decrypted;
    
}

What is the proper way to achieve it? because I need it to encrypt TLV values in QR code?

I am working on PHP 8.1 cloud shared server.

我仅修改了您的代码，但是我用有效的X509证书＆amp;替换了您的证书捆绑包；私钥。
公共密钥包含在证书中。您可以使用此命令来生成证书并键合：

openssl req -newkey rsa：2048 -new -x509 -days 3652 -nodes -out sp.crt sp.crt -keyout sp.pem -sha256，

您可以看到，该代码除了证书和某些线路中断外，代码是相同的。

I have modified your code only slightly, but I replaced your certificate bundle with a valid X509 certificate & private key.
The public key is contained within the certificate. You can generate certificate and keyfile yourself with this command:

openssl req -newkey rsa:2048 -new -x509 -days 3652 -nodes -out sp.crt -keyout sp.pem -sha256

As you see, the code is identical except for the certificate and some line breaks.
