GPG: Securely Transfer Files with Public Key Encryption

Today we'll cover how to encrypt and securely transfer files using GPG. GPG is a free, open-source encryption program that uses public-key cryptography, which means you can send encrypted files without ever having to send your private key over email or any other insecure channel. The only way to decrypt the file is if you have both your public and private keys, which means even if someone were able to intercept and read the message before it reached its intended recipient, it would be useless without the private key.
