Critical: build_leaf_cert self-signed leaves with the leaf key instead of
the YubiKey-held Intermediate CA key. Now extracts TBS, signs via
pkcs11-tool (ECDSA-SHA384), reassembles, and verifies against the
intermediate CA public key before returning.
- setup-certauth.sh: ~1100 lines of stale inline api/ copies replaced with
copy-from-repo (single source of truth); writes private
/etc/certauth/certauth.env (0600); DB init loads env, no more
swallowed errors; systemd unit gets EnvironmentFile=
- config.py: YubiKey serials no longer hard-coded (env, fail closed);
aarch64-only PKCS#11 path replaced with arch-neutral default; all
paths env-overridable (CERTAUTH_*)
- main.py: removed dead fastapi.security.CSRFProtection import (crashed
startup); module-relative static/templates dirs; created_by resolved
from the authenticated user instead of hard-coded 1; unclosed file
handles fixed; domain_id 0 stored as NULL (FK bug)
- models.py: certificates.domain_id FK pointed at users(id), now domains(id)
- login: CSRF token now actually sent and validated
- tests: 23 tests (auth, API flows, DER helpers, signing pipeline)
- README, LICENSE, requirements.txt, pyproject.toml
