openssl_pkcs7_encrypt problem

[grafix4d]

Hi all, I have php-7.4.4-Win32-vc15-x86, installed and want to use openssl_pkcs7_encrypt in order to encrypt a stream.

I prepare all input, checked all are ok, and after calling openssl_pkcs7_encrypt,

if (!openssl_pkcs7_encrypt($messageData, $encryptedMessage, $filestream, []))
	{
	// Check OpenSSL errors
    while ($error = openssl_error_string())
		{
        echo "OpenSSL error: $error\n";
    	}
	}
else
	{
	echo 'Encryption successful';
	}

I get error message:

OpenSSL error: error:02001002:system library:fopen:No such file or directory
OpenSSL error: error:2006D080:BIO routines:BIO_new_file:no such file

Please note that the cert file is read using:

$certfilepath = "C:/Users/user1/testfolder/test.cer";
$filestream = file_get_contents($certfilepath);

I think something has to do with openssl environment, because everything else seems fine.

Please help.

You want to encrypt a stream using functionality that encrypts files? That doesn't sound right...

"No such file or directory" sounds relevant. Does the $messageData file exist, and is it readable by PHP? Does the $encryptedMessage file exist, or at least its parent directory, and is it writable by PHP?
