program to learn Rust, Nix and to automate stuff for personal use.**\n\nManage your ssh access keys automatically by for ex. synchronizing them from github.\n\n## Installation\n\n```\n$ cargo install --locked klucznik\n```\n\n## Usage\n\n\u003e :warning:\n\u003e **Using a program to get authorized keys or allow SSH access based on data got from a remote server could be risky and insecure.\n\u003e If someone has control over the server you get the data from, or control over the network you're on then the attacker could easily\n\u003e inject their own keys and get full access to your machines.\n\u003e TL;DR use common sense!**\n\n### Install the binary (optional)\n\nInstall the binary to some globally accessible place:\n\n```bash\n$ sudo install --mode 755 --owner root --group root ~/.cargo/bin/klucznik /usr/local/bin/klucznik\n```\n\n### As `authorized_keys` updater\n\n:warning: this will overwrite your `authorized_keys` file!\n\nSet-up a cron job similar to this:\n\n```bash\n* 12 * * * /usr/local/bin/klucznik --sources https://github.com/\u003cyour username\u003e.keys --destination /home/\u003cuser\u003e/.ssh/authorized_keys\n```\n\nYou can add more sources via more flags.\n\nAlternatively, use [ssh-key-dir](https://github.com/coreos/ssh-key-dir) to not overwrite your `authorized_keys`:\n\n```bash\n* 12 * * * /usr/local/bin/klucznik --sources https://github.com/\u003cyour username\u003e.keys --destination /home/\u003cuser\u003e/.ssh/authorized_keys.d/klucznik\n```\n\nThen configure your `AuthorizedKeysCommand` in `sshd_config` to use `ssh-key-dir` to that ssh reads your overlays from that folder.\n\n### As `AuthorizedKeysCommand` (experimental!)\n\nChange the following settings in your `sshd_config`:\n\n```\nAuthorizedKeysCommand /usr/local/bin/klucznik --sources https://github.com/\u003cusername\u003e.keys\nAuthorizedKeysCommandUser root\n```\n\n`AuthorizedKeysCommand` is pretty picky about permissions, ownership etc. of that binary file. Make sure to read the proper `man` entry.\n\n## Roadmap\n\n### v0.1 'Not much more than overengineered `curl` replacement but works'\n\n- [x] configurable via command-line arguments/flags\n- [x] get authorized_keys from public URLs\n- [x] validate if in fact keys are returned (basic)\n- [x] save to file\n- [x] automated cargo release\n\n### v0.1.1\n\n- [x] fix writing multiple sources to one file\n- [x] if destination is provided, and file-contents are the same, don't overwrite\n- [x] if returned keys are empty, don't overwrite\n\n### v0.1.2\n\n- [x] fix created file permissions to 600\n\n### v0.2 '`curl` with centralized config'\n\n- [ ] deduplicate keys\n- [ ] config file support (remote + local)\n- [ ] able to read/store host-specific configuration\n\n### v0.3\n\n- [ ] add authenticated (private) URLs support\n\n### v1\n\n- [ ] refine `AuthorizedKeysCommand` support (ability to use this instead of `ssh-key-dir`.\n- [ ] ability to authorize directly from URLs (use `AuthorizedKeysCommand` and no `authorized_keys`\n- [ ] make sure cache data properly so that it can still authenticate if Github/Gitlab is currently down.\n- [ ] ability to chain commands in `AuthorizedKeysCommand`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkonradmalik%2Fklucznik","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkonradmalik%2Fklucznik","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkonradmalik%2Fklucznik/lists"}
