Adding SSH key to the ssh-agent

• Start the ssh-agent in the background eval "$(ssh-agent -s)"

Modify the SSH config

• Check to see if the config exists
• open ~/.ssh/config
• If the config doesn't exist, create it and then added the following content
• touch ~/.ssh/config

 Host *
  AddKeysToAgent yes
  UseKeychain yes

GPG Keys

Check for existing GPG keys

• gpg --list-secret-keys --keyid-format=long

ssb   rsa4096/3A260E8B789BD1DA 2022-07-16 [E]

Generate a GPG key and add it to GitHub

• Download the GPG Suite (will help prevent from having to enter GPG passphrase every time)
• gpg --full-generate-key
• Continue with the prompts but choose a bit size of 4096
• Provide the email of a verified email in github

Use an existing GPG key for signing commits

• gpg --armor --export <key_id> (Would be 1843A5F930706B28 from example above)
• Copy and paste the entire public key starting with the section that is -----BEGIN PGP PUBLIC KEY BLOCK----- and also copy the same part that is -----ENDS...
• Paste this into GitHub

Configure git with GPG

• git config --global commit.gpgsign true
• git config --global user.signingkey <key_id>
