Installation & Setup

To get started with `scan4secrets`, follow these steps:

1. Clone the Repository:

git clone https://github.com/scan4secrets/scan4secrets.git
cd scan4secrets

2. Install Dependencies:

pip install -r requirements.txt

3. Run scan4secrets:

python scan4secrets.py -d /path/to/your/code

Key Features

• Detects AWS keys, database credentials, JWT tokens, and more.
• Supports multiple programming languages.
• Integrates with CI/CD pipelines for automated scanning.

Advanced Usage

To scan a Git repository:

python scan4secrets.py -g https://github.com/example/repo.git

To exclude certain file types:

python scan4secrets.py -d /path/to/code --exclude ".log,.tmp"

Sample Output

[+] Scanning: /project/config/database.yml 
[!] Potential secret found: db_password = "s3cr3tP@ss" 
[+] Scan completed. 3 secrets detected. 

Integrating with Git Hooks

Add a pre-commit hook to prevent secrets from being committed:

!/bin/sh
python scan4secrets.py -d $(git diff --cached --name-only)
if [ $? -ne 0 ]; then
echo "Secrets detected! Commit blocked."
exit 1
fi

Linux & Windows Commands for Secret Management

• Linux: Use `grep` to manually search for secrets:

  grep -r "password|api_key|token" /path/to/code
  

• Windows (PowerShell):

  Select-String -Path ".config" -Pattern "password|secret|key"
  

What Undercode Say

Hardcoded secrets remain a leading cause of breaches. Tools like `scan4secrets` automate detection, but developers must adopt secure practices:
– Use environment variables or secret managers (e.g., Vault, AWS Secrets Manager).
– Rotate keys regularly.
– Implement pre-commit checks.

For robust security, combine SAST tools like `scan4secrets` with manual audits and threat modeling.

Expected Output:

[+] Scan completed. No hardcoded secrets detected.
