## Cheat Sheet
|
|
|
|
> Does the tedious work of making sure your `.ssh/authorized_keys` exists with
|
|
> the proper permissions, and that only valid keys from a given string, file, or
|
|
> URL go into it!
|
|
|
|
Use `ssh-authorize` to add trusted public keys to allow others to login to your
|
|
servers / systems / local computers;
|
|
|
|
```sh
|
|
# ssh-authorize <ssh-pubkey-or-file-or-url> [comment]
|
|
ssh-authorize https://github.com/jonny.keys 'My GitHub Keys'
|
|
```
|
|
|
|
```text
|
|
USAGE
|
|
|
|
ssh-authorize <ssh-pubkey-or-file-or-url> [comment]
|
|
|
|
EXAMPLES
|
|
|
|
ssh-authorize https://github.com/you.keys 'My GH Keys'
|
|
|
|
ssh-authorize ./id_rsa.you@example.co.pub
|
|
|
|
ssh-authorize 'ssh-rsa AAAA...example.co'
|
|
|
|
LOCAL IDENTIFY FILES
|
|
|
|
/home/app/.ssh/id_rsa.pub
|
|
```

### How to Add Manually
|
|
|
|
For the simplest case it seems almost silly to even have a utility for this:
|
|
|
|
```sh
|
|
mkdir -p ~/.ssh/
|
|
chmod 0700 ~/.ssh/
|
|
|
|
touch ~/.ssh/authorized_keys
|
|
chmod 0600 ~/.ssh/
|
|
|
|
curl https://github.com/me.keys >> ~/.ssh/authorized_keys
|
|
```
|
|
|
|
but... tedium, error checking... things are never as simple as they seem.
|
|
|
|
### But really, why?
|
|
|
|
- handles arbitrary files and URLs, failing bad key lines
|
|
- sets permissions correctly, even if they were incorrect
|
|
- works `curl` (macOS, Ubuntu) or `wget` (Docker, Alpine)
|
|
- enforces `https`
