TLS/SSL and crypto library

Small realization of a trusted timestamping service

Certificate-chain and trust-root validation for RFC 3161 timestamps. Source-available (BSL) layer for IRP (https://github.com/S0tman/irp-capture): turns "signature valid" into "witnessed by a timestamp authority you accept, and valid when it was issued."

A trust base for Agentic Commerce. Is a base standard for JWS-signed JSON receipts that are verifiable offline against a public JWKS endpoint. Protocols such a as X402, ACP, AP2, MCP, UCP and MCAP. Each receipt proves who the agent was, wich protocol ran, what trust providers voucher for the transaction, and what policy decision watch reached.
