+# Common Certificate Management Utilities
+
+This directory contains shared utilities for creating and managing custom TLS certificates using cert-manager in OpenStack operator kuttl tests.
+
+## Files
+
+- **`create_custom_cert.sh`** - Main script with bash functions for certificate creation
+- **`osp_check_route_cert.sh`** - Verification script for route certificates
+- **`verify_route_override_certs.sh`** - Verification script for OpenStackControlPlane overrides
+- **`prepare_placement_certs.sh`** - Helper script to create ConfigMap from certificates
+- **`custom-ingress-issuer.yaml`** - YAML template for custom ingress issuer
+- **`custom-internal-issuer.yaml`** - YAML template for custom internal issuer
+- **`custom-barbican-route.yaml`** - Pre-generated barbican route secret
+- **`custom-ca.yaml`** - Custom CA bundle for testing
+
+## Quick Reference
+
+### Create Certificates for Barbican and Placement
+
+```bash
+source ../../common/create_custom_cert.sh
+INGRESS_DOMAIN=$(oc get ingresses.config.openshift.io cluster -o jsonpath='{.spec.domain}')
+create_barbican_placement_routes "${INGRESS_DOMAIN}" "${NAMESPACE}"
+```
+
+### Main Functions
+
+| Function | Usage | Description |
+|----------|-------|-------------|
+| `create_barbican_placement_routes` | `<ingress-domain> [namespace]` | One-command setup for barbican and placement |
+| `create_service_route_certificate` | `<service-name> <ingress-domain> [namespace]` | Create certificate for any service |
+| `create_custom_issuer` | `<issuer-name> [namespace]` | Create root CA and issuer |
+| `create_wildcard_certificate` | `<cert-name> <domain> [issuer-name] [namespace]` | Create wildcard certificate |
+| `setup_custom_certificate_infrastructure` | `[namespace]` | Setup complete cert infrastructure |
+| `cleanup_custom_certificates` | `[namespace]` | Remove all custom certificates |
+
+### Verification Functions
+
+```bash
+# Verify route certificate matches secret
+bash ../../common/osp_check_route_cert.sh <service-name>
+
+# Verify OpenStackControlPlane override matches secret
+bash ../../common/verify_route_override_certs.sh <service-name>
+```
+
+## Certificate Specifications
+
+### Root CA Certificate
+- **Algorithm:** ECDSA P-256
+- **Duration:** 87600h (10 years)
+- **Usage:** Certificate Sign, CRL Sign
+- **IsCA:** true
+
+### Service Certificates
+- **Algorithm:** ECDSA P-256
+- **Duration:** 8760h (1 year)
+- **Renewal:** 720h (30 days) before expiration
+- **Usage:** Server Auth, Client Auth
+- **DNS Names:** `*.domain.com`, `domain.com`
+
+## Usage in Kuttl Tests
+
+```yaml
+apiVersion: kuttl.dev/v1beta1
+kind: TestStep
+commands:
+  - script: |
+      source ../../common/create_custom_cert.sh
+      INGRESS_DOMAIN=$(oc get ingresses.config.openshift.io cluster -o jsonpath='{.spec.domain}')
+      create_barbican_placement_routes "${INGRESS_DOMAIN}" "${NAMESPACE}"
+```
+
+## Examples
+
+### Create Certificates for Any Service
+
+```bash
+source ../../common/create_custom_cert.sh
+
+# For keystone
+create_service_route_certificate "keystone" "apps-crc.testing" "openstack-kuttl-tests"
+
+# For glance
+create_service_route_certificate "glance" "apps-crc.testing" "openstack-kuttl-tests"
+```
+
+### Setup Complete Infrastructure
+
+```bash
+# Creates both ingress and internal issuers
+setup_custom_certificate_infrastructure "openstack-kuttl-tests"
+```
+
+### Cleanup
+
+```bash
+# Remove all custom certificates and issuers
+cleanup_custom_certificates "openstack-kuttl-tests"
+```
+
+## Security Considerations
+
+⚠️ **Important:** These certificates are for **TESTING PURPOSES ONLY**
