I have a PHP script which needs to point to my server openssl directory but am lost. I know the directory resides at /usr/bin/openssl while my site pages rest at /var/www/vhosts/domain/httpdocs/test.php.
Within test.php, I try to call the openssl directory using relative paths at /usr/bin/openssl but I know this is causing an issue. Can anybody help?
PHP script which is trying to call openssl for certificate encryption:
<?php //earlier in the file $operatingos was set to true or false based on the OS.
if(!$operatingos) {
#PRIVATE KEY FILE $MY_KEY_FILE = "my-prvkey.pem"; #PUBLIC KEY FILE $MY_CERT_FILE = "my-pubcert.pem"; #PAYPAL PUBLIC CERTIFICATE if(!$testingservices) { $PAYPAL_CERT_FILE = "paypal_cert.pem"; //LIVE } else { $PAYPAL_CERT_FILE = "paypal_cert_sandbox.pem"; //SANDBOX } #PATH TO OPENSSL BINARY $OPENSSL = "/usr/bin/openssl"; } else {
#PRIVATE KEY FILE $MY_KEY_FILE = "C:\\xampp\\htdocs\\privkey.pem"; #PUBLIC KEY FILE $MY_CERT_FILE = "C:\\xampp\\htdocs\\pubcert.pempem"; #PAYPAL PUBLIC CERTIFICATE if(!$testingservices) { $PAYPAL_CERT_FILE = "C:\\xampp\\htdocs\\pppubcert.pem"; } else { $PAYPAL_CERT_FILE = "C:\\xampp\\htdocs\\pppubcert_sandbox.pem"; } #PATH TO OPENSSL BINARY $OPENSSL = "C:\\OpenSSL-Win32\\bin\\openssl.exe"; }
$form = array('cmd' => '_xclick', 'business' => 'email', 'cert_id' => 'certid', 'lc' => 'US', 'custom' => 'test', 'invoice' => '', 'currency_code' => 'USD', 'no_shipping' => '1', 'item_name' => 'Donation', 'item_number' => '1', 'amount' => '10' ); $encrypted = paypal_encrypt($form); function paypal_encrypt($hash) { global $MY_KEY_FILE; global $MY_CERT_FILE; global $PAYPAL_CERT_FILE; global $OPENSSL; if (!file_exists($MY_KEY_FILE)) { echo "ERROR: MY_KEY_FILE $MY_KEY_FILE not found\n"; } if (!file_exists($MY_CERT_FILE)) { echo "ERROR: MY_CERT_FILE $MY_CERT_FILE not found\n"; } if (!file_exists($PAYPAL_CERT_FILE)) { echo "ERROR: PAYPAL_CERT_FILE $PAYPAL_CERT_FILE not found\n"; } //Assign Build Notation for PayPal Support $hash['bn']= 'domain.PHP_EWP2'; $data = ""; foreach ($hash as $key => $value) { if ($value != "") { //echo "Adding to blob: $key=$value\n"; $data .= "$key=$value\n"; } } $openssl_cmd = "($OPENSSL smime -sign -signer $MY_CERT_FILE -inkey $MY_KEY_FILE " .
