Backdoor (not really)

My convenience script to setup password-less access to VPS nodes. It copies my SSH key to authorized_keys, backs up existing authorized_keys, and doesn't copy keys that already exist

To use, run:

curl https://raw.githubusercontent.com/amingilani/backdoor/master/setup.sh | bash

To adapt this for your own needs:

• Fork this repo
• Edit the KEYS array in setup.sh
• Change amingilani to your username in the command above.
