Implements a simplified version of the Signal Protocol's Double Ratchet algorithm using X25519, HKDF, and AES-256-GCM for end-to-end encrypted messaging.

Provides a comprehensive security checklist and code patterns for authentication, input validation, secrets management, SQL injection prevention, XSS, CSRF, rate limiting, and sensitive data exposure.

Store and retrieve API keys, passwords, and credentials in an HSM-backed encrypted vault via MCP or REST API, with policy-based access control, secret rotation, multi-chain signing, and prompt injection scanning.

Inventory cryptographic assets, deploy hybrid X25519 and ML-KEM key exchange, and prioritize migration of harvest-now-decrypt-later data.

Implements layered security for Flutter apps: code obfuscation, certificate pinning, secure storage, encryption, biometric authentication, and root/jailbreak detection.

Explains cryptographic primitives and provides Python implementations for encryption, hashing, key exchange, and digital signatures.

Analyzes cryptographic code to detect operations that leak secret data through execution timing variations, supporting multiple languages.

Implements FIDO2/WebAuthn hardware security key authentication with registration, authentication, YubiKey enrollment, and passkey migration using the python-fido2 library.

Generates, stores, validates, rotates, and revokes API keys with secure hashing, scoping, rate limiting, and leak monitoring.
