Encryption is a way of scrambling information so that only a legitimate recipient of that information can make it readable again. The most common form of encryption today is public key/private key encryption. Imagine a strongbox that has two keyholes and two separate keys. If you lock the box using one key, you can only unlock it with the other.
Security protocols
Hovering the padlock icon when visiting a secure server, you will see a string of text that looks something like this: TLS v1.0 128 bit C4 (1024 bit RSA/SHA)
The first three letters will show what security protocol is used on the site. There are four common security protocols; in order from good to best, these are SSL version 2, SSL version 3, TLS 1.0, and TLS 1.1.
SSL
SSL stands for "secure sockets layer". SSL version 3 is better than version 2, which is being phased out and is only used by a small number of Web sites these days.
TLS
TLS is short for "transport layer security", a security protocol based on SSL. This is considered the most secure protocol in common use today.
