Listed product details for crypt.fyi and Stroq
Detail	crypt.fyi	Stroq
Overview	The platform operates on a strict zero-knowledge architecture where all encryption happens directly in your browser, meaning servers never access unencrypted data or decryption keys. This client-side encryption model guarantees that your sensitive information remains completely private throughout the entire sharing process.	Stroq is an open‑source Agent Guard that runs on Node 22+ and inspects where a command originated before allowing it to execute. It normalizes tool output, tracks provenance of packages or URLs, and blocks outbound calls that contain indexed secrets, reporting the variable and file name. By hooking into Claude Code, Codex CLI, Cursor and similar agents, Stroq applies deterministic, model‑free policies and logs every decision, helping developers prevent secret leaks and unintended actions without sending data to external services.
Listed 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	Normalization: strips zero‑width characters, folds homoglyphs, and decodes base64, hex and URLs two levels deep. Provenance: records the earlier tool output that introduced a package, URL or command fragment and reports it when later used. Secret Egress Guard: indexes secrets as salted hashes and denies any outbound call that includes a known secret, naming the variable and source file.
