tldr; use git and github on the command line

this assumes you have a github account and a mac or linux machine

how to set up git and github on the command line st. you can push and pull without entering your password every time?

make sure to have git installed

brew install git # mac
sudo apt-get install git # linux, etc.

set up your git config

git config --global user.name "John Appleseed"
git config --global user.email "john@apple.com"

set up your ssh keys

ssh-keygen -t rsa -b 4096 -C "your.email@example.com"

copy the contents of the public key

pbcopy < ~/.ssh/id_rsa.pub # mac
xclip -sel clip < ~/.ssh/id_rsa.pub # linux

add the ssh key to your github account

clone a repo using ssh

git clone git@github.com:cristicretu/cretu.dev.git

you should be able to push and pull without entering your password

For mac users you can use the mac keychain to cache your password.

optional

signing your commits with a GPG key

brew install gpg2 gnupg pinentry-mac

create the .gnupg directory

mkdir ~/.gnupg
 
echo "pinentry-program $(brew --prefix)/bin/pinentry-mac" > ~/.gnupg/gpg-agent.conf

create `gpg.conf' file

echo 'use-agent' > ~/.gnupg/gpg.conf

add this to your ~/.bash_profile or ~/.zshrc

export GPG_TTY=$(tty)

restart terminal, and modify permissions

chmod 700 ~/.gnupg
killall gpg-agent

create a GPG key

gpg --full-gen-key

Use (4) RSA, 4096 bits, and a passphrase

gpg --list-secret-keys --keyid-format LONG

copy the key id (the part after rsa4096/)

gpg -K --keyid-format SHORT
sec rsa4096/######## YYYY-MM-DD [SC] [expires: YYYY-MM-DD]

export the key

gpg --armor --export ######## > public.key

configure git to use the key

git config --global gpg.program $(which gpg)
git config --glosbal user.signingkey ########
git config --global commit.gpgsign true

add the key to your github account

perform a signed commit

git commit -S -m "signed commit"
