🔒 Security

Kiwi Bridge Bot employs a multi-layered security framework to ensure the safety and privacy of user assets and private keys. Here's a detailed overview of the security measures:

1. Encryption of Private Keys

• AES-256-CBC Encryption: User private keys are encrypted using the industry-standard AES-256-CBC algorithm. This ensures that even if data is intercepted, it cannot be decrypted without the unique encryption key.

• Dynamic Initialization Vectors (IVs): Every encryption operation generates a unique IV to prevent pattern recognition attacks【14†source】.

2. Key Management

• Encrypted Storage: Encrypted private keys are securely stored in the bot's database, never in plaintext.

• Decryption on Demand: Private keys are only decrypted temporarily during authorized operations (e.g., signing transactions) and are never exposed in logs or responses【15†source】【16†source】.

3. Secure Communication

• End-to-End Encryption: All communication between users and the bot occurs over encrypted channels provided by Telegram.

• Environment Variables: The bot uses environment-secured master encryption keys, reducing exposure risks in the codebase or during deployment【15†source】.

4. Access Controls

• PIN Protection: Users are required to set up a 6-digit PIN for any wallet-related operations. This adds an additional layer of security against unauthorized access【16†source】.

• Role-Based Access: Operations like revealing private keys are gated behind explicit user authentication and PIN validation.

5. Compliance and Isolation

• Non-Custodial Design: The bot operates on a non-custodial framework, ensuring users maintain full ownership of their assets and private keys.

• Isolated Execution: Sensitive processes, such as key decryption or signing, are executed in isolated, sandboxed environments【16†source】.

6. Monitoring and Alerts

• Audit Logs: All key-related activities are logged and monitored for anomalous behavior.

• Transaction Verification: Users are notified of all wallet-related activities, ensuring immediate awareness of any unauthorized access attempts.

This robust combination of encryption, key management, and access controls ensures Kiwi Bridge Bot is a safe and secure platform for all cross-chain operations.
