Introduction
Security is not an afterthought at PassBangla—it's the foundation of everything we do. In this article, we'll explore the security measures that protect your passwords and data.
Client-Side Encryption
PassBangla uses client-side encryption, meaning your passwords are encrypted on your device before being sent to our servers. We use AES-256-CBC encryption, the same standard used by banks and government agencies.
Your encryption key is derived from your master password using PBKDF2, a key derivation function that makes it computationally infeasible to brute-force your key even if someone gains access to encrypted data.
Zero-Knowledge Architecture
PassBangla operates on a zero-knowledge principle. This means we cannot see, access, or decrypt your passwords. Even our own employees cannot view your data—only you have the keys to decrypt your passwords.
This architecture ensures that even in the unlikely event of a data breach, your passwords remain secure because they're encrypted with keys that only you possess.
User-Specific Encryption Keys
Each user has a unique encryption key derived from their credentials. This means that even if two users store the same password, they will be encrypted differently. Your encryption key never leaves your device in an unencrypted form.
This user-specific approach provides an additional layer of security, ensuring that your data is isolated from other users' data.
HTTPS Everywhere
All communication between your device and PassBangla servers is encrypted using HTTPS/TLS. This ensures that even if someone intercepts network traffic, they cannot read the data being transmitted.
We use the latest TLS protocols and maintain strong cipher suites to protect data in transit.
Breach Detection Integration
PassBangla integrates with the Have I Been Pwned database to check if your passwords have been compromised in known data breaches. This check is performed using k-anonymity, meaning we never send your full password to the service.
Instead, we send only the first 5 characters of your password's SHA-1 hash, and the service returns all hashes that start with those characters. We then check locally if your password's hash is in the results.
Compliance and Audits
PassBangla is designed with compliance in mind. Our security practices align with industry standards including GDPR, SOC 2, and other regulatory requirements.
We regularly conduct security audits and penetration testing to identify and address potential vulnerabilities before they can be exploited.
Best Practices
While PassBangla provides strong security, you also play a crucial role:
• Use a strong, unique master password
• Enable two-factor authentication
• Regularly review and update your passwords
• Keep your devices secure and up-to-date
• Be cautious of phishing attempts

Conclusion
Security is a shared responsibility. PassBangla provides the tools and infrastructure to keep your passwords secure, but following security best practices is essential for maximum protection.
