SSL is a security protocol developed by Netscape with the intention of providing security and confidentiality during the information transfer on the network.  It has become a standard supported by almost all of the internet browsers (Microsoft Explorer, Netscape, Navigator, etc.) with the release of its 3.0 version into the market in year 1996 and very wide application areas has been discovered.  SSL provides for the information sent to be decoded absolutely and only at the right address.  Information is coded automatically before it is transferred and can only be decoded by the right receiver.  The confidentiality and integrity of the information is protected by making verification on both sides.  The power of the coding method in data flow is connected to the length of the key.  Key length is very important for the protection of the information.  For example; it is very easy for a transmission sent over 8 bits to be decoded.  Bit, indicates a number in a binary system.  One bit can take 2 different values as 0 or 1.  8 bits on the other hand, contains only 28=256 possible different keys.  A computer can reach a conclusion by checking these 256 different possibilities one by one.  Saltysardine.com, which provides a virtual shopping service, uses security standards such as SSL and SET in order to establish this security and confidentiality.  These security systems are based on the transmission of information by coding during the data flow between the user, company and bank.  Therefore, by preventing the decoding of the information (in other words, preventing the usability of the information) in case that the information of the user falls onto the hands of other person, the confidentiality of the card information and security of shopping is provided.
