Undefined variable: pkeyCreated in ..RSA key creation failed..

I need to encrypt form data before sending it to server.

I found a nice solution form:

phpclasses.org/blog/package/9912/po ...

I downloading it and put at my home folder /hdesk/

but after run it from url https://localhost/cryptopost/test.php

it shows the below error:

Notice: Undefined variable: pkeyCreated in C:\xampp\htdocs\hdesk\cryptopost\Cryptopost.class.php on line 53
RSA key creation failed

Please give advice and solution.

I am using xampp

Apache/2.4.23 (Win32) OpenSSL/1.0.2h PHP/5.6.28

not working for at any browser.

I've tried to set configuration
c:>set OPENSSL_CONF=C:\xampp\htdocs\hdesk\cryptopost\openssl.cnf

but ho hope.

it always shows:

Notice: Undefined variable: pkeyCreated in C:\xampp\htdocs\hdesk\cryptopost\Cryptopost.class.php on line 53
RSA key creation failed

Sorry haven't tried to help you yet but I'm a full-time student right now and it's mid-term testing time I'll try to look at your problem later this week or maybe on the weekend.

When I'm using full path:
$crypto = new EncryptPost(1024, 'C:/xampp/htdocs/cryptopost/openssl.cnf');

everything works OK.

For further debugging use:

$pkey = openssl_pkey_new($config);
if(false === $pkey) {
echo openssl_error_string();
die;
}
