Secure Socket Layer a.k.a SSL

SSL is one method of data encryption in a communication made by Netscape Communications Corporation. As described in the SSL Protocol Internet Draft (The SSL Protocol, Version 3.0 by ALAN O. Freier and Paul C. Kocher, can you open the http://home.netscape.com/eng/ssl3/ssl-toc.html.

SSL is a layered protocol. In each layers, consisting of a long data, descriptions and content. SSL retrieve data to be sent, broken into blocks of order, then compressed, if necessary, apply the MAC, encrypted, and the results delivered. At the destination, data is decrypted, verified, decompress, and reassembled. The result is sent to the client on it. (free translation).

SSL will encrypt only data that is sent via http. How SSL walking can be described as follows:

* At the time the connection started to walk, the client and server create and share a secret key, which is used to encrypt data to be communicated. Although the session between the client and the server diintip other parties, but the data seem difficult to read because it is encrypted.
* SSL support public key cryptography, so the server can authenticate with the method commonly known as RSA and Digital Signature Standard (DSS).
* SSL may verify the integrity of the current session by using a digest algorithm such as MD5 and SHA. This avoids a session hijacking.
