PasswordSentinel is a demonstration project intended for educational purposes. While I do my best to implement modern security practices including AES-GCM encryption, users should be aware that this is not intended to be a primary password management solution. For sensitive data, please use established, professionally audited password managers.
- ✅ AES-GCM 256-bit encryption for stored passwords
- ✅ Secure key generation using Web Crypto API
- ✅ Protected local storage with encryption
- ✅ Secure error handling for cryptographic operations
- ✅ Modern password strength evaluation
- Encryption key stored in browser local storage
- No master password protection yet
- Client-side only security implementation
- Password generation uses Web Crypto API but could be further strengthened
- No automatic session timeout
We take security vulnerabilities seriously. If you discover a security vulnerability within PasswordSentinel, please follow these steps:
- Do Not disclose the vulnerability publicly until it has been addressed.
- Send details of the vulnerability to [email protected]
- Include the following information:
- Type of vulnerability
- Steps to reproduce
- Potential impact
- Suggested fixes (if any)
- Acknowledgment of your report within 48 hours
- Regular updates on the progress of addressing the vulnerability
- Credit for responsible disclosure (if desired)
- 24-48 hours: Initial acknowledgment of report
- 1 week: Assessment of vulnerability
- 2-4 weeks: Implementation of fix (depending on severity)
- Post-fix: Public disclosure and credit (if appropriate)
When using PasswordSentinel, please follow these security guidelines:
- Do not use this tool for storing highly sensitive passwords
- Regularly clear your browser's local storage
- Use a secure, up-to-date browser
- Be cautious when using on public or shared computers
- Enable your browser's security features
- Keep your operating system and browser updated
- Encrypted local storage using AES-GCM
- Master password protection
- Secure key generation
- Secure clipboard operations
- Auto-clear clipboard
- Session timeout
- Export/import encryption
- Password strength evaluation
- Secure error handling
- Algorithm: AES-GCM (256-bit)
- Key Generation: Web Crypto API
- Storage: Encrypted data with IV in local storage
- Error Handling: Graceful fallback with secure error messages
- Character set customization
- Minimum length enforcement
- Strength evaluation algorithms
- Visual strength indicators
Currently, PasswordSentinel uses minimal external dependencies:
- HTML5
- CSS3
- Vanilla JavaScript
- Web Crypto API (built-in browser feature)
This security policy may be updated from time to time. Please check back regularly to stay informed of any changes.
