A Deno Deploy server for managing and syncing SSH public keys across homelab machines.

Run the following command to install the sync script and set up hourly cron:

# As root:
curl -fsSL https://ssh-keys.kye.dev/install | sh

# Or with sudo:
curl -fsSL https://ssh-keys.kye.dev/install | sudo sh

This will:

1. Download sync.sh to /usr/local/bin/sync-ssh-keys
2. Make it executable
3. Add a cron job to run hourly
4. Run an initial sync

This server provides a managed subset of SSH keys that can be synced to ~/.ssh/authorized_keys on target machines. Pre-existing keys are preserved, while managed keys (between marker comments) are kept in sync with this server.

The sync script manages a section of your ~/.ssh/authorized_keys file between markers based on the server host:

# BEGIN SSH-KEYS.KYE.DEV MANAGED KEYS
# Auto-synced from https://ssh-keys.kye.dev
# Last updated: ...
ssh-ed25519 AAAA... user@host
# END SSH-KEYS.KYE.DEV MANAGED KEYS

Any keys outside these markers are preserved and unaffected by syncs.

1. Add .pub files to the keys/ directory
2. Deploy the server

All machines will pick up the changes on their next hourly sync.

To manually trigger a sync without installing:

curl -fsSL https://ssh-keys.kye.dev/sync.sh | sh

To update an existing install

curl -fsSL https://ssh-keys.kye.dev/reinstall | sh

curl https://ssh-keys.kye.dev/authorized_keys
