Thanks for your help Jaques,HTTPS isn't available on the clients server and not likely to be anytimes soon, so I'm gonna stick with a private key upload and checked with the public key on the target server. Alongside this will be a username and password encrypted with a constantly changing salt based on a number of variables. Once again, thanks for your input and I'll be sure to remember this for any future projects of a similar nature

What would you suggest then?

An encrypted username / password along with an openssl public private key combination.

Thanks for all your replies and suggestions. In all honesty I don't think it's worth going to all the trouble for this system as the data is not that sensitive. Their website is hosted on a shared server for starters, so I think it's a non-starter. I've come up with a different method which should be enough for them.

I've been asked to create a data exchange between two servers. The client is hot on security and wants a high security handshake to confirm the identity before proceeding. Their advisor suggested a private / public key certificate to authenticate the transfer. Exporting the data is fine. I've written many cURL scripts to send data to other servers using a public / private key system and I've already written the cURL for this system. The problem is handling the received certificate and authenticating it. I cannot find anything which relates to this type of transfer. The cURL we will use to send data is curl_setopt($ch, CURLOPT_SSLCERT, $certificate); curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM'); curl_setopt($ch, CURLOPT_SSLCERTPASSWD, $certificatePass); My problem is how to request the certificate in the response php file and verify the private certificate with the public key. Can anyone help?
