To receive full credit for this project, you will turn in the following two files:

A file named key.pub which includes your public key in ASCII format. Your public key must (1) use RSA encryption and be 4096 bits long, (2) be signed by at least two of your classmates, and (3) include your picture.

A file named message.txt.asc that is encrypted for me (Christo Wilson) and signed by you. The unencrypted message.txt file should be in plain ASCII format (no Word or PDF docs), and contain (1) your first and last name, (2) your NUID, and (3) the string "CS2550".

Tools

There are many tools that support the PGP standard. In the remainder of this document I will provide a brief tutorial for using GNU Privacy Guard (GnuPG, or simply GPG), which is a free, open-source, command line implementation of PGP. You are welcome to use other tools if you wish, so long as they offer the necessary features to complete all the requirements of the project.

To install GPG under a Debian-based Linux distro, simply run:

$ sudo apt install gnupg 

On some Linux distributions, such as Ubuntu 16.04, a slightly more up-to-date version of GPG can be installed via the "gnupg2" package instead (note that this method also changes the command to invoke GPG from "gpg" to "gpg2"). Other installation options for Linux, Windows, and macOS are available on the GnuPG homepage.
