Generate, distribute, audit, and securely delete SSH keys across all hosts in ~/.ssh/config.
SSH Key Sync Skill
This skill allows for managing SSH keys across a network, including generation, synchronization, status reporting, and secure deletion.
Capabilities
1. Generate and Sync Keys
Generate a new key pair: Automatically creates a new Ed25519 key with a unique name.
Optional Distribute: Copies the new private/public keys to all hosts in ~/.ssh/config unless --no-sync is specified.
Authorize keys: Appends the new public key to ~/.ssh/authorized_keys on the local machine and remote hosts.
Sync Config: Ensures the ~/.ssh/config file is consistent across all hosts during synchronization.
2. List Key Status
Management Table: Generates a table showing all managed keys, their types, and which hosts (local/remote) have them authorized.
3. Delete/Cleanup Keys
Secure Deletion: Removes specified keys from the local machine and all remote hosts.
Revoke Authorization: Automatically removes the public key entries from authorized_keys files locally and remotely to ensure the keys can no longer be used.
Usage
Direct Execution
You can run the script directly:
# Generate and sync to all hosts
~/git/dotfiles/src/ssh-key-sync/ssh-key-sync.sh <key_name>
# Generate locally only
~/git/dotfiles/src/ssh-key-sync/ssh-key-sync.sh --no-sync <key_name>
# List all keys and their sync status
~/git/dotfiles/src/ssh-key-sync/ssh-key-sync.sh --list
# Delete one or more keys
~/git/dotfiles/src/ssh-key-sync/ssh-key-sync.sh --delete <key_name1> <key_name2>
Natural Language Instructions
"Show me a table of all my SSH keys."
"Generate a new key called 'temp-key' and sync it."
"Clean up the test keys 'id_ed25519_new' and 'local_test_key' across all my hosts."
Workflow
Research: The skill identifies the user's intent (generate, sync, list, or delete).
Action: It executes ssh-key-sync.sh with the appropriate flags and key names.
Verification: It confirms the success of the requested management action.
