Cryptographic JSON Web Token (JWT) engine with RFC 7519 HMAC-SHA256 signature verification, claims validation, and expiration enforcement.
genpark-jwt-hmac-sha256-token-attestation-skill
Production-Grade Cryptographic Attestation & Security Agent Skill • 100% Standard Library Python • Native Model Context Protocol (MCP)
genpark-jwt-hmac-sha256-token-attestation-skill delivers zero-dependency, mathematically sound cryptographic attestation, zero-knowledge verification, and cybersecurity primitives engineered strictly using Python 3.9+ standard library.
🌟 Key Architectural Capabilities - Zero External Dependencies: Operates exclusively via pure Python (hashlib, hmac, secrets, time, json). Zero OpenSSL or C binding failures. - Enterprise Security Invariants: Implements formal SHA-256 Merkle root verification, RFC 7519 JWT HMAC-SHA256 signature parsing, 3-pass Schnorr zero-knowledge identification, constant-time equality validation, and sliding-window nonce replay protection. - Native Anthropic MCP Protocol: Compliant with standard JSON-RPC 2.0 stdio MCP specifications for Claude Desktop, Cursor, and Windsurf.
