SSH

What is SSH?

• Secure Socket Shell overview article

Generating keys and attaching them to your accounts

cd ~/.ssh
ssh-keygen -t rsa -C "your_email@youremail.com"
pbcopy < ~/.ssh/id_rsa.pub
# then add to your relative account

• GitHub
• Heroku
• Bitbucket

Multiple keys for multiple hosts (GitHub, BitBucket, Heroku etc)

• Detailed article here
• Note that keys can be any name, not just "id_rsa". You just have to configure it in your ssh/config like below.

ssh-keygen -t rsa -f ~/.ssh/accountB -C "your_email@youremail.com"
subl ~/.ssh/config

# contents of config file
Host bitbucket.org
  User git
  Hostname bitbucket.org
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_rsa

Host bitbucket-accountB
  User git
  Hostname bitbucket.org
