Show HN: VectorGuard-Nano – Free secure messaging for AI agents

[supere989]

I built VectorGuard-Nano, a lightweight secure messaging plugin for AI agents.

With MCP and agent frameworks exploding, agents need a way to communicate securely. This is MIT-licensed, HMAC-based obfuscation for casual agent messaging (Moltbook, Slack, IPFS, etc).

Features: - Deterministic encode/decode with shared secrets - Built-in timestamp handling - Zero dependencies (just Node crypto) - OpenClaw integration ready - Round-trip guaranteed

This is the "nano" version to show the concept. I'm also developing full VectorGuard with model-bound cryptography that solves the recently published Whisper Leak vulnerability.

Happy to answer questions!

Interesting direction, secure communication between agents is going to become increasingly critical as multi-agent workflows scale. We’re seeing a related challenge on the content-generation side as well, where multiple creative or generation agents coordinate to produce campaign-ready outputs, and maintaining secure, deterministic message passing becomes essential for reliability across pipelines. Tools that solve the messaging layer early could quietly become core infrastructure for agent ecosystems.

Thanks! That's exactly where I see this heading.

The deterministic message passing piece is key. With VectorGuard-Nano, agents can coordinate securely without manual key exchange, which becomes critical when you have 5, 10, 20+ agents in a pipeline.

Curious about your content-generation use case. Are you seeing specific pain points around agent coordination that current tools aren't addressing? Always looking for real-world requirements to inform the roadmap.

The full VectorGuard product I'm working on takes this further with model-bound cryptography and autonomous agent sync, which could be interesting for hyper-scale multi-agent systems. It also enables provenance tracking for auditable agent interactions. Happy to discuss if relevant to what you're building.
