Load whitelist/admins from a file

[shazow]

Maybe something like...

<fingerprint or pubkey>          # This whitelists the fingerprint
<nick> <fingerprint or pubkey>   # This reserves the nick to fingerprint
admin: <fingerprint or pubkey>   # This marks fingerprint as admin

Then we can have a --whitelist <file> flag, and a --whitelistOnly flag which disallows people to join if not on the whitelist.

i'd like to tackle this in my next PR. was thinking of just starting simple and having one fingerprint per line to allow access to connecting. i think maybe having another sort of config file for mapping fingerprints to nicks or admin/op privileges would solve the other problem. thoughts?

[jazzychad]

Also that way specifying the whitelist file would imply --whitelistOnly and wouldn't need to be another option

[shazow]

I GUESS! I'd like to support reserving names and marking admins in a similar fashion, but we can add it later.

Also I'd suggest supporting pubkey signatures, similar to ~/.ssh/known_hosts. Easier to fill them from github profiles and whatnot.

k, i just got the fingerprints working... can add pubkeys in a future PR?

[shazow]

pubkeys for future PR is cool. :)

[shazow]

Done. It accepts authorized_keys-style files now.

So, what is the format of the admin file again? Right now, a public key starts:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDpckxI...

How to make that public key an admin on a file I will pass to ssh-chat using the --admin parameter?

Basically it's one pubkey per line, as you wrote it.
