  2. What is Secure Sockets Layer (SSL)? • It is protection of data transferred over the Internet using encryption and enabled by a server's SSL Certificate. • An SSL Certificate contains a public key and a private key. A public key is used to encrypt information and a private key is used to decipher it.

  3. When a browser points to a secured domain, an SSL handshake authenticates the server and the client and establishes an encryption method and a unique session key. They can begin a secure session that protects message privacy and message integrity.

  4. SSL Does These Two Things • Authenticates the server and the client using public- key signatures. • Provides an encrypted connection for the client and server to exchange messages.

  5. SSL & E-Commerce Developed by Netscape in 1994 for transmitting private documents Has become the standard for e-commerce transaction security SSL encrypts data, like credit cards numbers and personal information Uses either 40-bit or 128-bit encryption I found that 40-bit encryption has been hacked

  6. Reasons Why You Would Use SSL • If you have an online store or accept online orders and credit cards • If you offer a login or sign in on your site • If you process sensitive data such as address, birth date, license, or ID numbers • If you need to comply with privacy and security requirements

  7. How to get an SSL Certificate Buy one from vendor – Can run about $400.00 per year. Or “self-sign” your own certificate using proprietary software. Self-Signed certificates will trigger a warning window in most browser configurations that will indicate that the certificate was not recognized.
