Lab Machine Setup Instructions

Important

(1) To access Github from the lab, you will need to make sure you are logged in as follows:

(2) Remember to (create a PAT and set your git credentials). Using the Console in RStudio:

create your PAT using usethis::create_github_token() ,
store your PAT with gitcreds::gitcreds_set() ,
tell Git to use your verified GitHub email and display name with
- usethis::use_git_config( user.name = "___", user.email = "___")

(3) Now go to the Terminal in RStudio and execute the remaining steps:

generate a key with a descriptive label: ssh-keygen -t ed25519 -C "8740-exam"
tell Git which key to use (execute these lines in the terminal, one at a time, and in order):
- git config gpg.format ssh
- git config user.signingkey ~/.ssh/id_ed25519.pub
- git config commit.gpgsign true
copy the key to the clipboard: cat ~/.ssh/id_ed25519.pub | clip
after running that command, the key is in your Windows clipboard.

Go to your personal Github account and navigate:
- there is a small circle on the upper right hand side of you personal github site,
- click on it to bring up a menu, and select settings (with a little gear symbol beside it)
- on the setting page, select SSH and GPG Keys (with a little key symbol beside it)
- the page that appears has a section labelled SSH Keys and a green button labelled New SSH key
- click the button and you’ll see a Key type dropdown. Select Signing Key, and finally
- paste the key in your clipboard into the Key textbox, and click the button Add SSH key.

(4) Test your commit in the RStudio Terminal.

Execute these lines, one at a time:
- git commit –allow-empty -S -m “verify signing”
- git log -1 –show-signature
You should see
- Good “git” signature for your_verified_github_email@example.com with SSH key SHA256:…
