+
+### Enrollment flow (device CSR → signed cert)
+- Device side
+  - Generate keypair on the device (never export private key).
+  - Create CSR with CN=<GUID> and URI SAN urn:device:<GUID>.
+
+- Server side
+  - Backend verifies a one-time enrollment token (or pre-shared bootstrap secret), calls:
+```bash
+vault write pki_iot/sign/device \
+  csr=@device.csr \
+  uri_sans="urn:device:<GUID>" \
+  ttl=720h > device_cert.pem
+```
+
+### Revocation
+- Immediate kill: your backend stores bad serials; deny in app logic.
+  - CRL: `vault write pki_iot/revoke serial_number="<SERIAL>"`.
+  - Fetch CRL periodically to a local file for Nginx:
+```bash
+curl -fsSL https://vault.example.local/v1/pki_iot/crl -o /etc/nginx/iot.crl
+nginx -s reload
+```
+  - Automate via systemd timer/cron (e.g., every 10–15 min).
+
+- Nginx fix for DER CRL format
+```bash
+# sed -i 's/\r$//' ./nginx/nginx_ssl/int_iot.crl
+curl http://vault.local:8200/v1/pki_iot/crl -o nginx/nginx_ssl/int_iot.crl
