# agenix - [age](https://github.com/FiloSottile/age)-encrypted secrets for NixOS
|
||||
|
||||
`agenix` is a small and convenient Nix library for securely managing and deploying secrets using common public-private SSH key pairs:
|
||||
You can encrypt a secret (password, access-token, etc.) on a source machine using a number of public SSH keys,
|
||||
and deploy that encrypted secret to any another target machine that has the corresponding private SSH key of one of those public keys.
|
||||
This project contains two parts:
|
||||
1. An `agenix` commandline app (CLI) to encrypt secrets into secured `.age` files that can be copied into the Nix store.
|
||||
2. An `agenix` NixOS module to conveniently
|
||||
* add those encrypted secrets (`.age` files) into the Nix store so that they can be deployed like any other Nix package using `nixos-rebuild` or similar tools.
|
||||
* automatically decrypt on a target machine using the private SSH keys on that machine
|
||||
* automatically mount these decrypted secrets on a well known path like `/run/agenix/...` to be consumed.
|
||||
`agenix` is a commandline tool for managing secrets encrypted with your existing SSH keys. This project also includes the NixOS module `age` for adding encrypted secrets into the Nix store and decrypting them.

You can obtain the public keys from

4. Create a secret file:
|
||||
4. Edit secret files (these instructions assume your SSH private key is in ~/.ssh/):
|
||||
```ShellSession
|
||||
$ agenix -e secret1.age
|
||||
```
|
||||
It will open a temporary file in the app configured in your $EDITOR environment variable.
|
||||
When you save that file its content will be encrypted with all the public keys mentioned in the `secrets.nix` file.
|
||||
5. Add secret to a NixOS module config:
|
||||
```nix
|
||||
{
|
||||
age.secrets.secret1.file = ../secrets/secret1.age;
|
||||
}
|
||||
```
|
||||
When the `age.secrets` attribute set contains a secret, the `agenix` NixOS module will later automatically decrypt and mount that secret under the default path `/run/agenix/secret1`.
|
||||
Here the `secret1.age` file becomes part of your NixOS deployment, i.e. moves into the Nix store.
|
||||
|
||||
6. Reference the secrets' mount path in your config:
|
||||

|
||||
}
|
||||
```
|
||||
You can reference the mount path to the (later) unencrypted secret already in your other configuration.
|
||||
So `config.age.secrets.secret1.path` will contain the path `/run/agenix/secret1` by default.
|
||||
7. Use `nixos-rebuild` or [another deployment tool](https://nixos.wiki/wiki/Applications#Deployment") of choice as usual.
|
||||
7. NixOS rebuild or use your deployment tool like usual.
|
||||
|
||||
The `secret1.age` file will be copied over to the target machine like any other Nix package.
|
||||
Then it will be decrypted and mounted as described before.
|
||||
8. Edit secret files:
|
||||
```ShellSession
|
||||
$ agenix -e secret1.age
|
||||
```
|
||||
It assumes your SSH private key is in `~/.ssh/`.
|
||||
In order to decrypt and open a `.age` file for editing you need the private key of one of the public keys
|
||||
it was encrypted with. You can pass the private key you want to use explicitly with `-i`, e.g.
|
||||
```ShellSession
|
||||
$ agenix -e secret1.age -i ~/.ssh/id_ed25519
|
||||
```
|
||||
The secret will be decrypted to the value of `config.age.secrets.secret1.path` (`/run/agenix/secret1` by default).

# Problem and solution {#problem-and-solution}
|
||||
|
||||
All files in the Nix store are readable by any system user, so it is not a suitable place for including cleartext secrets. Many existing tools (like NixOps deployment.keys) deploy secrets separately from `nixos-rebuild`, making deployment, caching, and auditing more difficult. Out-of-band secret management is also less reproducible.
|
||||
|
||||
`agenix` solves these issues by using your pre-existing SSH key infrastructure and `age` to encrypt secrets into the Nix store. Secrets are decrypted using an SSH host private key during NixOS system activation.

## `age` module reference {#age-module-reference}
|

|
||||
### `age.secrets`
|
||||
|
||||
`age.secrets` attrset of secrets. You always need to use this
|
||||
configuration option. Defaults to `{}`.
|
||||
|
||||
### `age.secrets.<name>.file`
|
||||
|
||||
`age.secrets.<name>.file` is the path to the encrypted `.age` for this
|
||||
secret. This is the only required secret option.
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.monitrc.file = ../secrets/monitrc.age;
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secrets.<name>.path`
|
||||
|
||||
`age.secrets.<name>.path` is the path where the secret is decrypted
|
||||
to. Defaults to `/run/agenix/<name>` (`config.age.secretsDir/<name>`).
|
||||
|
||||
Example defining a different path:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.monitrc = {
|
||||
file = ../secrets/monitrc.age;
|
||||
path = "/etc/monitrc";
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
For many services, you do not need to set this. Instead, refer to the
|
||||
decryption path in your configuration with
|
||||
`config.age.secrets.<name>.path`.
|
||||
|
||||
Example referring to path:
|
||||
|
||||
```nix
|
||||
{
|
||||
users.users.ryantm = {
|
||||
isNormalUser = true;
|
||||
passwordFile = config.age.secrets.passwordfile-ryantm.path;
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
#### builtins.readFile anti-pattern
|
||||
|
||||
```nix
|
||||
{
|
||||
# Do not do this!
|
||||
config.password = builtins.readFile config.age.secrets.secret1.path;
|
||||
}
|
||||
```
|
||||
|
||||
This can cause the cleartext to be placed into the world-readable Nix
|
||||
store. Instead, have your services read the cleartext path at runtime.
|
||||
|
||||
### `age.secrets.<name>.mode`
|
||||
|
||||
`age.secrets.<name>.mode` is permissions mode of the decrypted secret
|
||||
in a format understood by chmod. Usually, you only need to use this in
|
||||
combination with `age.secrets.<name>.owner` and
|
||||
`age.secrets.<name>.group`
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.nginx-htpasswd = {
|
||||
file = ../secrets/nginx.htpasswd.age;
|
||||
mode = "770";
|
||||
owner = "nginx";
|
||||
group = "nginx";
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secrets.<name>.owner`
|
||||
|
||||
`age.secrets.<name>.owner` is the username of the decrypted file's
|
||||
owner. Usually, you only need to use this in combination with
|
||||
`age.secrets.<name>.mode` and `age.secrets.<name>.group`
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.nginx-htpasswd = {
|
||||
file = ../secrets/nginx.htpasswd.age;
|
||||
mode = "770";
|
||||
owner = "nginx";
|
||||
group = "nginx";
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secrets.<name>.group`
|
||||
|
||||
`age.secrets.<name>.group` is the name of the decrypted file's
|
||||
group. Usually, you only need to use this in combination with
|
||||
`age.secrets.<name>.owner` and `age.secrets.<name>.mode`
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.nginx-htpasswd = {
|
||||
file = ../secrets/nginx.htpasswd.age;
|
||||
mode = "770";
|
||||
owner = "nginx";
|
||||
group = "nginx";
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secrets.<name>.symlink`
|
||||
|
||||
`age.secrets.<name>.symlink` is a boolean. If true (the default),
|
||||
secrets are symlinked to `age.secrets.<name>.path`. If false, secerts
|
||||
are copied to `age.secrets.<name>.path`. Usually, you want to keep
|
||||
this as true, because it secure cleanup of secrets no longer
|
||||
used. (The symlink will still be there, but it will be broken.) If
|
||||
false, you are responsible for cleaning up your own secrets after you
|
||||
stop using them.
|
||||
|
||||
Some programs do not like following symlinks (for example Java
|
||||
programs like Elasticsearch).
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets."elasticsearch.conf" = {
|
||||
file = ../secrets/elasticsearch.conf.age;
|
||||
symlink = false;
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secrets.<name>.name`
|
||||
|
||||
`age.secrets.<name>.name` is the string of the name of the file after
|
||||
it is decrypted. Defaults to the `<name>` in the attrpath, but can be
|
||||
set separately if you want the file name to be different from the
|
||||
attribute name part.
|
||||
|
||||
Example of a secret with a name different from its attrpath:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secrets.monit = {
|
||||
name = "monitrc";
|
||||
file = ../secrets/monitrc.age;
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `age.ageBin`
|
||||
|
||||
`age.ageBin` the string of the path to the `age` binary. Usually, you
|
||||
don't need to change this. Defaults to `age/bin/age`.
|
||||
|
||||
Overriding `age.ageBin` example:
|
||||
|
||||
```nix
|
||||
{pkgs, ...}:{
|
||||
age.ageBin = "${pkgs.age}/bin/age";
|
||||
}
|
||||
```
|
||||
|
||||
### `age.identityPaths`
|
||||
|
||||
`age.identityPaths` is a list of paths to recipient keys to try to use to
|
||||
decrypt the secrets. By default, it is the `rsa` and `ed25519` keys in
|
||||
`config.services.openssh.hostKeys`, and on NixOS you usually don't need to
|
||||
change this. The list items should be strings (`"/path/to/id_rsa"`), not
|
||||
nix paths (`../path/to/id_rsa`), as the latter would copy your private key to
|
||||
the nix store, which is the exact situation `agenix` is designed to avoid. At
|
||||
least one of the file paths must be present at runtime and able to decrypt the
|
||||
secret in question. Overriding `age.identityPaths` example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.identityPaths = [ "/var/lib/persistent/ssh_host_ed25519_key" ];
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secretsDir`
|
||||
|
||||
`age.secretsDir` is the directory where secrets are symlinked to by
|
||||
default.Usually, you don't need to change this. Defaults to
|
||||
`/run/agenix`.
|
||||
|
||||
Overriding `age.secretsDir` example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secretsDir = "/run/keys";
|
||||
}
|
||||
```
|
||||
|
||||
### `age.secretsMountPoint`
|
||||
|
||||
`age.secretsMountPoint` is the directory where the secret generations
|
||||
are created before they are symlinked. Usually, you don't need to
|
||||
change this. Defaults to `/run/agenix.d`.
|
||||
|
||||
|
||||
Overriding `age.secretsMountPoint` example:
|
||||
|
||||
```nix
|
||||
{
|
||||
age.secretsMountPoint = "/run/secret-generations";
|
||||
}

To rekey a secret, you have to be able to decrypt it. Because of
|
||||
randomness in `age`'s encryption algorithms, the files always change
|
||||
when rekeyed, even if the identities do not. (This eventually could be
|
||||
improved upon by reading the identities from the age file.)

# Threat model/Warnings {#threat-model-warnings}
|
||||
|
||||
This project has not been audited by a security professional.
|
||||
|
||||
People unfamiliar with `age` might be surprised that secrets are not
|
||||
authenticated. This means that every attacker that has write access to
|
||||
the secret files can modify secrets because public keys are exposed.
|
||||
This seems like not a problem on the first glance because changing the
|
||||
configuration itself could expose secrets easily. However, reviewing
|
||||
configuration changes is easier than reviewing random secrets (for
|
||||
example, 4096-bit rsa keys). This would be solved by having a message
|
||||
authentication code (MAC) like other implementations like GPG or
|
||||
[sops](https://github.com/Mic92/sops-nix) have, however this was left
|
||||
out for simplicity in `age`.

# Tutorial {#tutorial}
|
||||
|
||||
1. The system you want to deploy secrets to should already exist and
|
||||
have `sshd` running on it so that it has generated SSH host keys in
|
||||
`/etc/ssh/`.
|
||||
|
||||
2. Make a directory to store secrets and `secrets.nix` file for listing secrets and their public keys (This file is **not** imported into your NixOS configuration. It is only used for the `agenix` CLI.):
|
||||
|
||||
```ShellSession
|
||||
$ mkdir secrets
|
||||
$ cd secrets
|
||||
$ touch secrets.nix
|
||||
```
|
||||
3. Add public keys to `secrets.nix` file (hint: use `ssh-keyscan` or GitHub (for example, https://github.com/ryantm.keys)):
|
||||
```nix
|
||||
let
|
||||
user1 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIL0idNvgGiucWgup/mP78zyC23uFjYq0evcWdjGQUaBH";
|
||||
user2 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILI6jSq53F/3hEmSs+oq9L4TwOo1PrDMAgcA1uo1CCV/";
|
||||
users = [ user1 user2 ];
|
||||
|
||||
system1 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIPJDyIr/FSz1cJdcoW69R+NrWzwGK/+3gJpqD1t8L2zE";
|
||||
system2 = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKzxQgondgEYcLpcPdJLrTdNgZ2gznOHCAxMdaceTUT1";
|
||||
systems = [ system1 system2 ];
|
||||
in
|
||||
{
|
||||
"secret1.age".publicKeys = [ user1 system1 ];
|
||||
"secret2.age".publicKeys = users ++ systems;
|
||||
}
|
||||
```
|
||||
4. Edit secret files (these instructions assume your SSH private key is in ~/.ssh/):
|
||||
```ShellSession
|
||||
$ agenix -e secret1.age
|
||||
```
|
||||
5. Add secret to a NixOS module config:
|
||||
```nix
|
||||
{
|
||||
age.secrets.secret1.file = ../secrets/secret1.age;
|
||||
}
|
||||
```
|
||||
6. Use the secret in your config:
|
||||
```nix
|
||||
{
|
||||
users.users.user1 = {
|
||||
isNormalUser = true;
|
||||
passwordFile = config.age.secrets.secret1.path;
|
||||
};
|
||||
}
|
||||
```
|
||||
7. NixOS rebuild or use your deployment tool like usual.
|
||||
|
||||
The secret will be decrypted to the value of `config.age.secrets.secret1.path` (`/run/agenix/secret1` by default).
