Learning about Cryptography.

As part of on-going studies towards my Security+ certificate, I’ve recently learned about Symmetric and Asymmetric cryptography.

To put into practice some words from a textbook: I’ve created a public GPG key for Asymmetric cryptography!

You can use this key to encrypt binary files or text messages that only I can decrypt. This process is known as Asymmetric cryptography – as there is a unique secret key I keep and another Public key for anyone to use. Encryption like this is important for maintaining security across the globe. The process uses algorithms to transform plaintext data (Or basic binary data such as an image) into something called ciphertext. The algorithm itself is called a cipher. The ciphertext is effectively a bunch of gibberish that is unreadable without something called a “Private Key”. The two part output of Asymmetric encryption is a Public Key and the Private key.

The Public key can be used as a one way process to send secure data across an unencrypted medium. The additional security provided by a GPG Public key ensures confidentiality when transmitting packets over the internet.

So please send me an email to everett@everettdahling.ca using the following key:

(Copy and paste the entire block into a text file and use something like Kleopatra to encrypt the data.)

My fingerprint is: 1853 5F78 21CD 0112 A91D 68AF BA0C 5740 D857 A621
