What is encryption?

Since there has been so much news lately about the Heartbleed bug and other viruses I thought it would be a good time to talk a bit about encryption.

Encryption is an important part of Internet Safety although it is something that you do not see or do anything about. It takes what you type on the computer (input) and puts it into a code so that while it is traveling over the wires no one can intercept it and steal that information. When your message arrives at the other end it is decrypted so that it can be read.

At this time most Banks, PayPal, and other Websites that involve money or information that needs to stay secure use strong encryption. It is also a major concern of Doctors and Hospitals as they put patient information online. 

Unlike most posts this does not end with something that you should do. Encryption is good to know about. It is automatically done at many sites.

Good security is an important part of doing business online. The good thing for us users is that the companies are possibly more concerned with safety than we are. They know that if they are unable to provide secure transmissions on their site they will lose customers.
