# SCEP Service Documentation
## Overview
This mkcert Web UI now includes SCEP (Simple Certificate Enrollment Protocol) support, allowing devices to automatically request and receive certificates. This implementation provides a simplified SCEP server that generates certificates using mkcert.
## SCEP Endpoints
### Standard SCEP Endpoints
#### Get CA Capabilities
```bash
GET /scep?operation=GetCACaps
```
Returns the SCEP server capabilities:
- Renewal
- SHA-1
- SHA-256
- DES3
- AES
#### Get CA Certificate
```bash
GET /scep?operation=GetCACert
```
Downloads the CA certificate in PEM format. This certificate should be installed on client devices for certificate validation.
#### PKI Operation (Implemented)
```bash
POST /scep?operation=PKIOperation
Content-Type: multipart/form-data
```
Handles PKCS#7 certificate requests with SCEP protocol support. This endpoint:
1. **Parses PKCS#7 SCEP requests** using node-forge library
2. **Validates challenge passwords** against active challenge store
3. **Extracts certificate signing requests** from PKCS#7 enveloped data
4. **Generates certificates** using mkcert for valid requests
5. **Returns PKCS#7 responses** with proper SCEP message format
**Request Format:**
- Multipart form data with `message` field containing PKCS#7 binary data
- PKCS#7 message should contain encrypted CSR and optional challenge password
- Transaction ID and nonces are handled automatically
**Response Format:**
- Success: `application/x-pki-message` containing PKCS#7 certificate response
- Failure: `application/x-pki-message` containing SCEP failure message with appropriate error codes
**Supported SCEP Message Types:**
- PKCSReq: Certificate signing request
- CertRep: Certificate response (success/failure)
**Error Handling:**
- Invalid PKCS#7: Returns `badRequest` failure
- Expired/invalid challenge: Returns `badRequest` failure
- Certificate generation failure: Returns `systemFailure` failure
### Management API Endpoints (Authenticated)
#### Get SCEP Configuration
```bash
GET /api/scep/config
```
Returns complete SCEP server configuration including URLs and capabilities.
#### Generate Challenge Password
```bash
POST /api/scep/challenge
Content-Type: application/json
{
"identifier": "device-001",
"expiresIn": 3600
}
```
Generates a challenge password for SCEP clients.
#### List Challenge Passwords
```bash
GET /api/scep/challenges
```
Lists all active challenge passwords with their status.
#### Manual Certificate Generation
```bash
POST /api/scep/certificate
Content-Type: application/json
{
"commonName": "test.example.com",
"challengePassword": "optional-challenge"
}
```
Generates a certificate using the SCEP workflow (for testing purposes).
#### List SCEP Certificates
```bash
GET /api/scep/certificates
```
Lists all certificates generated via SCEP.
#### Get Certificate Details
```bash
GET /api/scep/certificates/:commonName
```
Returns details for a specific SCEP-generated certificate.
## Web Interface
Access the SCEP management interface at: `http://localhost:3000/scep.html`
The web interface provides:
- SCEP configuration display
- Challenge password generation and management
- Manual certificate generation for testing
- List of SCEP-generated certificates

</dict>
</plist>
```
### Windows Certificate Template
For Windows SCEP clients, configure with:
- SCEP URL: `http://localhost:3000/scep`
- Challenge Password: Generated via web interface
- Key Length: 2048 bits
- Hash Algorithm: SHA-256
## Security Notes
1. **Development Use**: This SCEP implementation is designed for development and testing environments.
2. **Challenge Passwords**: Generate challenge passwords via the web interface before enrolling devices.
3. **HTTPS Recommended**: For production use, enable HTTPS by setting `ENABLE_HTTPS=true`.
4. **Rate Limiting**: SCEP endpoints are rate-limited to prevent abuse:
- CLI operations: 10 requests per 15 minutes
- API operations: 100 requests per 15 minutes
5. **Authentication**: Management API endpoints require authentication.
## Certificate Storage
SCEP-generated certificates are stored in:
```
certificates/
├── scep/
│ ├── domain1.example.com/
│ │ ├── domain1.example.com.pem
│ │ └── domain1.example.com-key.pem
│ └── domain2.example.com/
│ ├── domain2.example.com.pem
│ └── domain2.example.com-key.pem
└── temp/
└── [temporary CSR files]
```
## Implementation Details
### PKCS#7 Message Processing
The SCEP implementation includes full PKCS#7 message parsing using the `node-forge` library:
**Components:**
- `src/utils/pkcs7.js` - PKCS#7 parsing and generation utilities
- `src/routes/scep.js` - SCEP protocol endpoint handlers
- `node-forge` - Cryptographic operations and ASN.1 parsing
- `asn1js` - Additional ASN.1 support for complex structures
**Message Flow:**
1. **Request Parsing**: PKCS#7 signed data structures are parsed to extract:
- Enveloped CSR data (requires decryption)
- Challenge passwords from authenticated attributes
- Transaction IDs and nonces for message tracking
2. **Certificate Generation**: Valid requests trigger:
- mkcert CLI execution for certificate creation
- Proper domain validation and certificate storage
- Integration with existing certificate management system
3. **Response Generation**: SCEP-compliant responses include:
- PKCS#7 signed data containing generated certificates
- Proper SCEP message types (CertRep)
- Success/failure status with appropriate error codes
### Security Features
- **Challenge Password Validation**: Time-based expiration and one-time use
- **Request Rate Limiting**: Prevents abuse of certificate generation
- **Command Injection Protection**: Secured mkcert CLI execution
- **Path Traversal Prevention**: Validated certificate storage paths
## Testing
### Web Interface
Use the web interface at `/scep.html` to:
1. Generate challenge passwords
2. Test certificate generation
3. View SCEP configuration
4. Monitor certificate status
### Command Line Testing
Test PKI operations directly:
```bash
# Test CA certificate retrieval
curl "http://localhost:3000/scep?operation=GetCACert"
# Test SCEP capabilities
curl "http://localhost:3000/scep?operation=GetCACaps"
# Test PKI operation with PKCS#7 message
curl -X POST "http://localhost:3000/scep?operation=PKIOperation" \
-F "message=@path/to/pkcs7-request.p7m"
```
## Limitations
- **CSR Extraction**: Enveloped data decryption requires additional implementation
- **Full SCEP Compliance**: Some advanced SCEP features not implemented
- **Certificate Revocation**: Not implemented (CRL/OCSP support)
- **Production Security**: Intended for development/testing environments
## Future Enhancements
- Complete PKCS#7 enveloped data decryption
- Certificate revocation list (CRL) support
- Integration with external Certificate Authorities
- Enhanced security for production deployments
- Enhanced security features
- Certificate renewal automation
## Troubleshooting
### Common Issues
1. **mkcert not found**: Ensure mkcert is installed and in PATH
2. **Permission errors**: Check certificate directory permissions
3. **Authentication failures**: Verify credentials and session configuration
4. **Rate limiting**: Wait for rate limit window to reset
### Debug Mode
Enable debug logging by setting environment variables:
```bash
DEBUG=scep* npm start
```
### Log Files
Check console output for SCEP-related events:
- Challenge password generation
- Certificate requests
- Error conditions

<h2><i class="fas fa-info-circle"></i> SCEP Service Overview</h2>
<p>
SCEP (Simple Certificate Enrollment Protocol) allows devices to automatically request and receive certificates from this mkcert Web UI service.
This implementation provides a simplified SCEP server that generates certificates using mkcert.
</p>
<div class="alert alert-info">
<strong>Note:</strong> This is a simplified SCEP implementation designed for development and testing environments.
For production use, consider a full-featured SCEP server.
