# GCP Secret Manager Scanner
A Python tool for scanning Google Cloud Platform Secret Manager across all regions to discover and retrieve secrets. Useful for security audits, secret inventory, and cloud resource discovery.
## Features
- Scan all GCP regions for secrets in a single command
- Multiple authentication methods (access token, token file, or service account key)
- Optional secret value retrieval
- Export results to JSON
## Installation
```bash
git clone https://github.com/5epi0l/GCPSecretFinder.git
cd GCPSecretFinder
pip install -r requirements.txt
```
## Authentication
The tool supports three authentication methods:
### 1. Access Token (Direct)
```bash
python3 gcpsecretfinder.py --project my-project --token "ya29.c.b0Aaek..."
```
### 2. Access Token (From File)
```bash
python3 gcpsecretfinder.py --project my-project --token-file ~/token.txt
```
### 3. Service Account Key
```bash
python3 gcpsecretfinder.py --project my-project --service-account-key ~/key.json
```
## Usage Examples
### Basic Scanning
List all secrets across all regions:
```bash
python3 gcpsecretfinder.py --project gr-proj-8 --token-file ~/token.txt
```
### Retrieve Secret Values
Scan and retrieve the actual secret values:
```bash
python3 gcpsecretfinder.py --project my-project --token-file ~/token.txt --retrieve
```
### Retrieve Specific Version
Get a specific version of secrets instead of latest:
```bash
python3 gcpsecretfinder.py --project my-project \
--token-file ~/token.txt \
--retrieve \
--version 2
```
## Command-Line Options
```
required arguments:
-p, --project PROJECT GCP project ID
authentication (one required):
-t, --token TOKEN Access token (String)
-f, --token-file FILE Path to file containing access token
-s, --service-account-key Path to service account key file
optional arguments:
--retrieve Retrieve secret values (not just list them)
--version VERSION Secret version to retrieve (default: latest)
-h, --help Show help message
```
## Supported Regions
The tool scans the following regions by default:
**Asia Pacific:**
- asia-east1, asia-east2
- asia-northeast1, asia-northeast2, asia-northeast3
- asia-south1, asia-south2
- asia-southeast1, asia-southeast2
- australia-southeast1, australia-southeast2
**Europe:**
- europe-central2
- europe-north1
- europe-west1, europe-west2, europe-west3, europe-west4, europe-west6
**Middle East:**
- me-central1, me-west1
**North America:**
- northamerica-northeast1, northamerica-northeast2
- us-central1
- us-east1, us-east4
- us-west1, us-west2, us-west3, us-west4
**South America:**
- southamerica-east1, southamerica-west1
## Output Format
### JSON Output
With `--retrieve`, secrets are retrieved in JSON format:
```json
[
{
"name": "projects/123456/secrets/api-key",
"region": "us-east1",
"value": "sk-abc123...",
"version": "latest",
"full_data": {
"name": "projects/123456/secrets/api-key",
"createTime": "2024-01-15T10:30:00Z",
"labels": {},
"replication": {
"automatic": {}
}
}
}
]
```
## Common Use Cases
### Security Audit
```bash
# Find all secrets and retrieve them
python3 gcpsecretfinder.py \
--project prod-project \
--service-account-key ~/audit-sa.json \
--retrieve
```
### Secret Inventory
```bash
# List all secrets without retrieving values
python3 gcpsecretfinder.py \
--project my-project \
--token-file ~/token.txt \
```
### Integration with Other Tools
```bash
# Pipe to jq for filtering
python3 gcpsecretfinder.py \
--project my-project \
--token-file ~/token.txt \
--retrieve \
| jq '.[] | select(.name | contains("production"))'
```
## Permissions Required
The service account or user must have the following IAM permissions:
- `secretmanager.secrets.list` - To list secrets
- `secretmanager.versions.access` - To retrieve secret values (when using `--retrieve`)
## Error Handling
The tool handles common errors gracefully:
- Network timeouts (10 second timeout per request)
- Invalid credentials
- Missing permissions
- Non-existent regions
- Failed secret retrieval
Errors are logged to stderr while scanning continues for remaining regions.
## Performance Considerations
- Each region is scanned sequentially to avoid rate limiting
- Default timeout is 10 seconds per region
- Scanning all 31 regions typically takes 30-60 seconds
- Retrieval adds additional time proportional to number of secrets found
