rfc3161-client

Warning

This project is currently in beta. While it is already being used in production by downstream projects, we reserve the right to make breaking changes to the API. We recommend pinning to specific versions until we reach a stable 1.0 release.

rfc3161-client is a Python library implementing the Time-Stamp Protocol (TSP) described in RFC 3161.

It is composed of three subprojects:

• 🦀 tsp-asn1: A Rust crate using rust-asn1 to create the types used by the Time-Stamp protocol. This crate depends on rust-asn1 and cryptography to minimize the amount of duplicated code. While it is usable as a standalone crate, this is not officially supported. Drop us a message if you are interested in using it.
• 🦀 rfc3161-client: Another Rust crate that provides Python bindings to the tsp-asn1 crate using PyO3.
• 🐍 rfc3161-client A Python library using the crate above to provide a usable API to create Timestamp Request and read Timestamp Response.

Goals and anti-goals

• This library should be correct and provide an accurate implementation of protocol described in the RFC 3161.
• This library does not perform any network activity, it simply provides primitive to build and verify objects. Network activity must be handled separately.
