Secure Sockets Layer
Short for Secure Sockets Layer, it is a protocol developed by Netscape for transmitting private documents via the Internet. Secure Sockets Layer uses a cryptographic system that uses two keys to encrypt data - a public key known to everyone and a private or secret key known only to the recipient of the message. Both Netscape Navigator and Internet Explorer support Secure Sockets Layer, and many Web sites use the protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an Secure Sockets Layer connection start with https: instead of http:.
The Wikipedia web encyclopidia describes how the Secure Sockets Layer protocol works by exchanging records; each record can be optionally compressed, encrypted and packed with a message authentication code (MAC). Each record has a content_type field that specifies which upper level protocol is being used.
When the connection starts, the record level encapsulates another protocol, the handshake protocol, which has content_type 22.
The client sends and receives several handshake structures:
It sends a ClientHello message specifying the list of cipher suites, compression methods and the highest protocol version it supports. It also sends random bytes which will be used later.
Then it receives a ServerHello, in which the server chooses the connection parameters from the choices offered by the client earlier.
When the connection parameters are known, client and server exchange certificates (depending on the selected public key cipher). These certificates are currently X.509, but there's also a draft specifying the use of OpenPGP based certificates.
The server can request a certificate from the client, so that the connection can be mutually authenticated.
Client and server negotiate a common secret called "master secret", possibly using the result of a Diffie-Hellman exchange, or simply encrypting a secret with a public key that is decrypted with the peer's private key. All other key data is derived from this "master secret" (and the client- and server-generated random values), which is passed through a carefully designed "Pseudo Random Function".
