#ed25519

A Messaging Layer Security (RFC 9420, MLS) implementation in TypeScript

Common cryptographic library used in software at Mysten Labs.

Open protocol for AI agent accountability. Cryptographic identity, scoped delegation that narrows per hop, gateway enforcement, signed receipts for every action. TypeScript reference, Apache-2.0.

Framework-agnostic Solana transaction signing with multiple backends. Unified trait interface, async-first design, and feature-gated compilation for minimal dependencies.

All the things a panda needs

The IAM layer for AI agents: cryptographic identity, capability authorization, and audit trails for non-human identities. Open source.

A pure-Rust implementation of group operations on Ristretto and Curve25519

Portable signed records for automated interactions.

A best-effort, pure-Rust port of Tailscale's Go tsnet — embed a Tailscale node directly in your Rust app. Fork of tailscale/tailscale-rs.

Drop-in authentication for Go: Argon2id passwords, EdDSA JWTs with refresh rotation, opaque API keys, OIDC + OAuth2 social login, email + username validation. Secure by default, zero boilerplate.

Verifiable agent actions. Every action becomes signed context for the next. Ed25519 signatures, Merkle log proofs, independently verifiable by anyone.

The Linux of AI - an open, federated, self-hosted AI operating system. Humans, AI agents, and local LLMs share apps, knowledge, and capabilities on nodes you own. MIT.

One scan for AI risk. `opena2a review` checks an AI project across credentials, shadow agents, MCP servers, and dependencies, returns a score, and routes each finding to the tool that fixes it. Open source.

Agent Receipts — cryptographically signed audit trails for AI agent actions. Protocol spec, SDKs (Go, TypeScript, Python), and MCP proxy.

Identity, memory, and soul for AI agents. Runs standalone or as part of a TPS office.

This library is designed to be small, flexible and convenient wrapper for a variety crypto algorithms. So it can be used in a small micro controller as well as in a high load server application.

Offline cryptographic receipts for AI evaluation results — Ed25519 + RFC 6962 Merkle + optional SD-JWT. Integrity, not truth

Mutual ZKP authentication for humans and AI agents

Go implementation of JSON Web Tokens (JWT).

Production-ready Python library & CLI for Open Badges 3.0 (W3C Verifiable Credentials): issue, verify, and revoke JWT-VC credentials with Bitstring Status Lists and did:web — plus strict OB 2.0 and legacy OB 1.0.

Portable trust receipts for agent workflows. Signed, chained, verifiable.
