With Google search over SSL, you can have an end-to-end encrypted search solution between your computer and Google.

Why would you want to encrypt your communications with a search engine? If the data you send to and receive from a search site is encrypted with SSL, it won't be readable to anyone who intercepts it with packet sniffing software. So if you're worried that the keywords you're searching could implicate or embarrass you, or you just prefer to keep that information private, you might want to use the secure version of Google Search.

To use Google's search over SSL, visit  this link  each time you perform a search.
