Home Free Secure Email Certificate The first is encryption—ensuring that nobody can understand the communication between a client and a server—and the second is authentication—proving to the client that it is actually communicating with the server it thinks it's communicating with.
They would like to encrypt the information they send each other, but to do this, they both need to be using the same encryption key. Obviously, they cannot just send the key to each other, because anyone listening in on the connection will be able to watch them do so, and use the key to decrypt the communication themselves. Fortunately, clever mathematics allows both parties to share an encryption key without it being disclosed to any eavesdroppers.
But what if instead of merely eavesdropping, the malicious party actually interferes with the connection, placing itself between the client and the server, intercepting everything sent between the two, known as a man-in-the-middle MITM attack. This would be a big problem. The MITM could act as the server as far as the client was concerned and the client as far as the server were concerned , sharing one key with the client and another with the server.
He could then decrypt anything the client said, examine it, and then re-encrypt it and send it to the server, and neither side would be any the wiser. This is where authentication, in the form of certificates, comes to the rescue.
Certificates are an application of public key cryptography. With normal encryption , the key used to encrypt data is the same key as is used to decrypt data; if you know the key, you can both encrypt and decrypt as you see fit. Public key cryptography, however, uses two keys: a private key, that is kept secret, and a public key, that is shared with the world.
Each key only works "one way"; anything encrypted with the public key can only be decrypted with the private key, and anything encrypted with the private key can only be decrypted with the public key. Public key cryptography is very powerful, because it enables the establishment of trust.
If a public key can be used to decrypt a piece of information then it's all but certain that the information was originally encrypted with the corresponding private key. And so, this mechanism is built into SSL. The server publishes a certificate—a little chunk of data that includes a company name, a public key, and some other bits and pieces—and when the client connects to the server, it sends the server some information encrypted using the public key from the certificate.
The server then decrypts this using its private key. This information is used to encrypt subsequent communication. Since only the server knows the private key—and hence only the server can decrypt the information encrypted with the public key—this allows the client to prove that it's communicating with the rightful owner of the certificate. That's still not quite enough to safeguard against MITM attacks, however. So there's one more piece to the puzzle: a chain of trust.
To verify the authenticity and identity of the certificates themselves, they are linked back to a trustworthy source of certificates. Instead of simply generating a certificate oneself called a "self-signed certificate" , one instead pays some money to a Certificate Authority CA and has it generate the certificate.
