crypt.fyi

Built for security-conscious professionals, developers, and organizations who need to share passwords, API keys, confidential documents, or other sensitive data, Crypt.fyi addresses the growing need for quantum-resistant cryptography. The platform features burn-after-reading functionality with provisions to prevent erroneous burns from bots or URL introspection, ensuring secrets are automatically deleted after viewing.

Key Features

• Post-Quantum ML-KEM Encryption: Uses NIST-standardized Module-Lattice-based Key Encapsulation Mechanism for quantum-resistant security
• Zero-Knowledge Architecture: Browser-based encryption ensures servers never see unencrypted data or decryption keys
• Burn After Reading: Automatic secret deletion after viewing with bot protection mechanisms
• Open Source Transparency: Fully auditable codebase for security verification and community contributions
• Content Security Policy: Strict CSP implementation to prevent XSS attacks and unauthorized resource loading

Who This Is For

• Security Professionals: Teams requiring quantum-resistant encryption for sensitive data sharing
• Software Developers: Engineers sharing API keys, database credentials, and configuration secrets securely
• IT Administrators: Organizations needing compliant, auditable secret transmission for compliance requirements

Common Questions

Q: How does post-quantum encryption differ from traditional encryption? A: ML-KEM encryption resists attacks from both classical and quantum computers, unlike traditional methods vulnerable to quantum computing.

Q: Can the service provider access my shared secrets? A: No, all encryption occurs in your browser before transmission, implementing true zero-knowledge architecture.

Q: What happens to secrets after they're viewed? A: Secrets are automatically and permanently deleted from servers after viewing, with safeguards against accidental deletion from bots.

Q: Is the code available for security auditing? A: Yes, Crypt.fyi is completely open-source, allowing full security audits and community contributions.
