About this video
We’re not all security experts, but we still need to be aware of security itself, in order to protect ourselves in the digital age.
So, welcome to the Basics of Encryption (Part 1), where we get a very gentle introduction into the world of cryptography. If you want to know what is cryptography, then this video is for you!
Cryptography / Encryption has been around for years. Consider the Caesar Cipher and Enigma, both forms of substitution cipher. These were used during wartime to convert plain text to cipher text, without enemy forces understanding the original message.
And although old, both of these forms of encryption help us to gain an understanding into modern encryption.
These days encryption is more complicated, using prime numbers to create keys that are near impossible to guess, and too hard to compute. That is of course, if you use them correctly...
