description: Secure secrets management with age encryption, root-protected keys, and GF(3) conservation via DuckDB/ACSet catalog
version: 1.0.0
trit: -1  # Validator/constrainer role in GF(3) triadic system

Overview

fnox is a secrets management tool that encrypts secrets with age and stores them in a git-safe fnox.toml. This skill documents the secure setup with root-protected keys and ACSet-aligned DuckDB catalog.

Installation

# Install fnox via cargo
cargo install fnox

# Install age via flox (or brew)
flox install age

# Generate age keypair
mkdir -p ~/.age
age-keygen -o ~/.age/key.txt

Configuration

Initialize fnox

cd ~
fnox init
fnox provider add myage age

Edit fnox.toml

[providers.myage]
type = "age"
recipients = ["age1your_public_key_here"]

[profiles.default]
# Default profile secrets

[profiles.prod]
# Production secrets

[profiles.staging]
# Staging secrets

Commands

Set a Secret

fnox set SECRET_NAME "secret_value" --provider myage
fnox set DATABASE_URL "postgres://..." --provider myage
fnox set API_KEY "sk-..." --provider myage -p prod  # prod profile

Get a Secret

fnox get SECRET_NAME --age-key-file ~/.age/key.txt

# With root-protected key
sudo cat /var/keys/age/key.txt > /tmp/k && fnox get SECRET_NAME --age-key-file /tmp/k && rm /tmp/k

List Secrets

fnox list
fnox list -p prod  # prod profile only

Run Command with Secrets as Env Vars

fnox exec --age-key-file ~/.age/key.txt -- ./my-app
fnox exec --age-key-file ~/.age/key.txt -- env | grep APTOS

Import/Export

fnox export --format env > .env.encrypted
fnox import --format env < .env

Profiles

fnox profiles                    # List profiles
fnox set KEY "val" -p prod      # Set in prod profile
fnox get KEY -p prod            # Get from prod profile
FNOX_PROFILE=prod fnox list     # Use prod by default

Shell Integration

Add to ~/.zshrc:

# fnox secret management (GF(3) integrated)
export FNOX_AGE_KEY_FILE=~/.age/key.txt
eval "$(~/.cargo/bin/fnox activate zsh)"

For root-protected keys, use the wrapper:

# /usr/local/bin/fnox-secure
#!/bin/bash
TEMP_KEY=$(mktemp)
trap "rm -f $TEMP_KEY" EXIT
sudo cat /var/keys/age/key.txt > "$TEMP_KEY"
~/.cargo/bin/fnox --age-key-file "$TEMP_KEY" "$@"

Root-Protected Key Setup

Move Keys to Root Storage

sudo mkdir -p /var/keys/{age,aptos/worlds,aptos/testnet}
sudo cp ~/.age/key.txt /var/keys/age/
sudo cp ~/.aptos/worlds/*.key /var/keys/aptos/worlds/
sudo chown -R root:wheel /var/keys
sudo chmod -R 600 /var/keys
sudo chmod 700 /var/keys /var/keys/age /var/keys/aptos /var/keys/aptos/worlds

Verify

sudo cat /var/keys/age/key.txt > /tmp/k && fnox get TEST_SECRET --age-key-file /tmp/k && rm /tmp/k

DuckDB Catalog

Schema

CREATE TABLE identity (id INTEGER PRIMARY KEY, name VARCHAR, path VARCHAR, trit TINYINT);
CREATE TABLE keypair (id INTEGER PRIMARY KEY, identity_id INTEGER, pubkey VARCHAR, privkey_path VARCHAR, algorithm VARCHAR, trit TINYINT);
CREATE TABLE provider (id INTEGER PRIMARY KEY, name VARCHAR, trit TINYINT);
CREATE TABLE profile (id INTEGER PRIMARY KEY, name VARCHAR, trit TINYINT);
CREATE TABLE secret (id INTEGER PRIMARY KEY, name VARCHAR, keypair_id INTEGER, provider_id INTEGER, profile_id INTEGER, trit TINYINT);

Query Examples

# List all secrets
duckdb ~/.config/keys/catalog.duckdb "SELECT name FROM secret"

# Check GF(3) conservation
duckdb ~/.config/keys/catalog.duckdb "SELECT * FROM gf3_total"

# Find Aptos keys
duckdb ~/.config/keys/catalog.duckdb "SELECT name FROM secret WHERE name LIKE 'APTOS%'"

GF(3) Conservation

All entities are assigned trits (-1, 0, +1) such that:

Σ(trits) ≡ 0 (mod 3)

Entity	Trit Assignment
age identity	-1 (validator)
ssh identity	0 (coordinator)
gpg identity	+1 (generator)
default profile	0
prod profile	+1
staging profile	-1
secrets	cyclic: -1, 0, +1, -1, ...

Files

~/.cargo/bin/fnox              # fnox binary
~/fnox.toml                    # Encrypted secrets (git-safe)
/var/keys/age/key.txt          # Root-protected age key

Troubleshooting

"No providers configured"

fnox provider add myage age
# Then edit fnox.toml to set recipients

"Cannot decrypt"

# Check age key path
fnox get SECRET --age-key-file ~/.age/key.txt

# For root-protected
sudo cat /var/keys/age/key.txt > /tmp/k && fnox get SECRET --age-key-file /tmp/k; rm /tmp/k

"Secret not found"

fnox list  # Check secret exists
fnox list -p prod  # Check correct profile
