Parameters for >> openssl_pkcs7_decrypt

[isas_n]

Is this part of code is correct?

1. I have given 777 permission to the secrypted.msg file.
2. I was unable to decrypt the message.
3. Give exact definitions for the parameters passed to the function
4. Do we want to store the encrypted message explicitly to the encrypted.msg file?

<?php

echo "Decrypt the message"."<br>";

// this file holds your encrypted message
$infilename = "/var/www/html/testing/encrypt/smime.p7m";

// make sure you can write to this file
$outfilename = "/var/www/html/testing/encrypt/decrypted.msg";

$cert = "/var/www/html/testing/encrypt/sasikumar.crt";
$key = "/var/www/html/testing/encrypt/sasikumar.pfx";

if (openssl_pkcs7_decrypt($infilename, $outfilename, $cert, $key))
{
echo "decrypted!";
}
else
{
echo "failed to decrypt!";
}

fclose($infilename);
fclose($fp);

?>
