I'm sending some parameters (string) from my PC using delphi to a PHP script on my website server using the POST method.
The parameters im using should be encrypted. So my delphi program encrypts and sends the encrypted string (parameters) to my PHP script that exists on my website server, and my PHP script should decrypt the parameters. I prefer using rijndael 128 bit encryption but if there's any other encryption method it would be fine. The main point is i want my delphi to encrypt and my PHP script to decrypt the string that delphi encrypted.
I found this package: http://www.cityinthesky.co.uk/cryptography.html
it has a rijndael 128 encryption vcl component for delphi.
It also provides an example on how to encrypt using delphi and php in this link: http://www.cityinthesky.co.uk/files/PHPEncryption.zip
However, when i test the demo they have, the encrypted string is different in the delphi app than the string in php script.
