SSL TLS HTTPS Web Server Certificate Fingerprints  

Public and Private keys form cryptographically matched pairs. It is not feasible to derive one from the other, yet what one encrypts only the matching other can decrypt. Website SSL security certificates provide the site’s Public cryptographic key which is the public side of the server’s secret Private cryptographic key which is never publicly disclosed. Only the certificate’s public key can be used to encrypt data which the remote server can decrypt only using its matching private key. Since the SSL Proxy Appliance does not have the private key of the remote server—because only the remote server has it—the fake & fraudulent certificate the SSL Proxy provides to the user’s web browser is forced to use a different public key for which it does have a matching private key. And that means that no matter how hard any SSL-intercepting Proxy Appliance may try to spoof and fake any other server’s certificate, the certificate’s public key MUST BE DIFFERENT

The remote server’s REAL certificate and the SSL Appliance’s FAKED certificate MUST HAVE AND WILL HAVE radically different fingerprints.  They will not be remotely similar..
