For humans and agents.
Send to a teammate, a temporary AI agent, or a trusted automation from one consistent experience.
SECURE EXCHANGE FOR HUMANS + AI AGENTS
Share credentials, configuration, and sensitive information with a person or an AI agent—without dropping plaintext into a chat, a channel, or a prompt. SynthSecret combines recipient-bound encryption, temporary agent identity, and auditable delivery.
Encrypted for the intended recipient. Time-limited delivery.
Built on NodeVertex.
THE PRIVATE PATH BETWEEN ENDPOINTS01 / A BETTER BOUNDARY
Teams increasingly work alongside autonomous agents. But a password pasted into a conversation can outlive the task, reach unintended participants, or be retained by systems that were never meant to store it. SynthSecret gives sensitive exchanges their own protected path.
02 / PURPOSE-BUILT EXCHANGE
Send to a teammate, a temporary AI agent, or a trusted automation from one consistent experience.
An agent can establish a temporary self-asserted cryptographic identity through AI PPort. No full persona registration required.
Payloads are encrypted for the recipient before reaching SynthSecret storage.
Initiate a secret exchange from a collaboration polygon while keeping plaintext out of the channel.
Set expiration, retrieval limits, and authorization rules. Delivery controls do not erase a secret after it has been decrypted.
See who was authorized and when retrieval occurred, without logging secret contents.
03 / IDENTIFY → ENCRYPT → DELIVER
A person and an agent establish recipient keys.
The sender protects the payload locally.
Only the intended recipient can open it.
Identify. Choose a person or agent. Temporary agents can establish an AIAL-1 identity in moments.
Protect. Your client encrypts the secret for the recipient's verified public key.
Deliver. SynthSecret brokers authorized retrieval and records the exchange state—without reading the plaintext.
FOR AUTONOMOUS AGENTS
Agents can enroll for temporary identities, publish public keys through pubkey.sh, request exchange grants through Interagentic, and retrieve encrypted envelopes through a documented API.

Choose a recipient, set a time window, and deliver an encrypted secret through a focused experience built for clarity.
Share SecurelyFOR SYN TEAMS
Initiate exchanges from a Syn polygon. Collaborators see delivery status, not secret contents.

A temporary agent credential proves control of a cryptographic key—not who trained the agent or which organization it represents. SynthSecret surfaces assurance levels clearly, binds exchanges to recipients, and keeps authorization separate from collaboration membership.
