For all those interested, I have set up PGP (public key: text / ASC) so that I can encrypt and digitally sign (so that you can authenticate that it was actually me who created the file or message and that it hasn’t been changed since I created and signed it) outgoing messages and files and everyone else can encrypt and digitally sign messages and files sent to me. PGP works (very simply explanation) by providing individuals with two sets of keys, a public key and a private key. The public key is distributed to everyone else, while the private key is kept by the individual. When someone wants to send you an encrypted file or message, they encrypt the file or message with your public key, and you decrpyt it with your private key. When you want to send someone else a message or file, you encrpyt it with their public key and they decrypt it with their private key. When you want to sign a message or file, you do so using your private key, and the individual your sending it to can verify your signature with your public key. When someone else signs a message or file and sends it to you, you can verify their signature with their public key. You can both sign and encrypt a file at the same time as well for security and authentication. PGP is relatively straight-forward and simple, but has a lot of functionality and levels to it.
