我将库“ jsencrypt”用于js

html＆amp; JS＆amp; ajax到php（将加密的文本发送到PHP文件以进行解密）

    encrypt.setPublicKey(servPubKeyPem);
    var encryptedText = encrypt.encrypt('Hello my friend!');

    $.ajax({
        type: "POST",
        url: 'test.php',
        data: {'encryptedText' : encryptedText},
        success: function(data) {
            
        }
    });
</script>

</body>
</html>

：

<?php

    $encryptedText = $_POST['encryptedText'];

    $priKeyPem = file_get_contents('../php/priKey.pem');
    
    $priKey = openssl_pkey_get_private($priKeyPem); //PriKey - PrivateKey - (he is work) 
  openssl_private_decrypt($encryptedText, $decryptedText, $priKey);

    # but $decryptedText == null ...

?>

我需要在JS中加密文本，在PHP和PHP中通过加密文本进行了加密，但是在PHP中，我得到了“ null” ...请帮助：/

</script>

</body>
</html>

PHP:

<?php

    $encryptedText = $_POST['encryptedText'];

    $priKeyPem = file_get_contents('../php/priKey.pem');
    
    $priKey = openssl_pkey_get_private($priKeyPem); //PriKey - PrivateKey - (he is work) 
  openssl_private_decrypt($encryptedText, $decryptedText, $priKey);

    # but $decryptedText == null ...

?>

I need to encrypt the text in JS pass the encrypted text in PHP and in PHP decrypt it, but in PHP I get "null"... Please help :/
