Encryption – Part 3 – Using a More Complex Key

This is another in a series of posts about Protective Technologies. Here we are going to continue to examine the use of a key, but a more complex key compared to the last post: Encryption – Part 2 – Using a Key, to encrypt our communications. Encryption has evolved over the centuries and today's encryption […]

Encryption – Part 2 – Using a Key

This is another in a series of posts about Protective Technologies. Encryption in any of its forms is, arguably, the most important of the Protective Technologies that help keep us safe while using the Internet. Today's encryption methods are quite sophisticated compared to those of the past, and here we are going to discuss the […]
