# Credential Scanner Implementation Summary
|
||||
|
||||
**Date:** 2026-01-16
|
||||
**Module:** `api/utils/credential_scanner.py`
|
||||
**Status:** ✓ Complete and Tested

|
||||
|
||||
## What Was Built
|
||||
|
||||
A comprehensive credential scanner and importer for the ClaudeTools context import system that:
|
||||
|
||||
1. **Scans directories** for credential files (credentials.md, .env, passwords.txt, etc.)
|
||||
2. **Parses multiple formats** (Markdown, environment files, text)
|
||||
3. **Auto-detects credential types** (API keys, passwords, connection strings, tokens)
|
||||
4. **Imports to database** with automatic AES-256-GCM encryption
|
||||
5. **Creates audit logs** for compliance and security tracking

|
||||
## Features Implemented
|
||||
|
||||
### 1. File Scanning (`scan_for_credential_files`)
|
||||
- Recursive directory traversal
|
||||
- Smart file pattern matching
|
||||
- Exclusion of build/cache directories
|
||||
- Supports: credentials.md, .env, passwords.txt, secrets.md, auth.md
|
||||
|
||||
### 2. Multi-Format Parsing (`parse_credential_file`)
|
||||
|
||||
**Markdown Format:**
|
||||
```markdown
|
||||
## Service Name
|
||||
Username: admin
|
||||
Password: secret123
|
||||
API Key: sk-1234567890
|
||||
```
|
||||
|
||||
**Environment Format:**
|
||||
```bash
|
||||
DATABASE_URL=mysql://user:pass@host/db
|
||||
API_KEY=sk-1234567890
|
||||
```
|
||||
|
||||
**Auto-detects:**
|
||||
- Service names from headers
|
||||
- Credential types from value patterns
|
||||
- Internal vs external URLs
|
||||
- 20+ key variations (username/user/login, password/pass/pwd, etc.)
|
||||
|
||||
### 3. Type Detection (`_detect_credential_type`)
|
||||
|
||||
**Patterns recognized:**
|
||||
- API keys: `sk-*`, `api_*`, `ghp_*`, `gho_*`, `xoxb-*`
|
||||
- SSH keys: `-----BEGIN * PRIVATE KEY-----`
|
||||
- Connection strings: `mysql://`, `postgresql://`, `Server=...`
|
||||
- JWT tokens: 3-part base64 format
|
||||
- OAuth tokens: `ya29.*`, `ey*`, `oauth*`
|
||||
|
||||
### 4. Database Import (`import_credentials_to_db`)
|
||||
- Uses existing `credential_service` for encryption
|
||||
- Creates audit log entries (action: "create")
|
||||
- Never logs plaintext credentials
|
||||
- Continues on errors (partial import support)
|
||||
- Returns success count
|
||||
|
||||
### 5. Convenience Function (`scan_and_import_credentials`)
|
||||
- One-line full workflow
|
||||
- Returns detailed statistics
|
||||
- Supports client association
|
||||

|
||||
|
||||
## Security Features
|
||||
|
||||
### Encryption
|
||||
- **Algorithm:** AES-256-GCM (via Fernet)
|
||||
- **Encrypted fields:** password, api_key, client_secret, token, connection_string
|
||||
- **Key management:** Environment variable `ENCRYPTION_KEY`
|
||||
- **Per-credential:** Unique initialization vectors
|
||||
|
||||
### Audit Trail
|
||||
Every import creates audit log with:
|
||||
- `credential_id` - Reference to imported credential
|
||||
- `action` - "create"
|
||||
- `user_id` - From function parameter
|
||||
- `ip_address` - From function parameter (optional)
|
||||
- `timestamp` - Auto-generated
|
||||
- `details` - Service name, credential type
|
||||
|
||||
### Safe Logging
|
||||
- Plaintext credentials **NEVER** logged
|
||||
- Only file paths and counts logged
|
||||
- Service names (non-sensitive) logged
|
||||
- Errors logged without credential values
|
||||

||||
- Offer update vs create choice
|
||||
- Compare by service_name + username
|
||||
|
||||
3. **Add credential validation**
|
||||
- Test API keys before import
|
||||
- Verify connection strings
|
||||
- Check password strength
|
||||
|
||||
4. **Add bulk operations**

||||
@router.post("/credentials/import")
|
||||
async def import_from_file(
|
||||
file: UploadFile,
|
||||
client_id: Optional[UUID] = None,
|
||||
db: Session = Depends(get_db)
|
||||
):
|
||||
"""REST API endpoint for file upload and import"""
|
||||
pass
