SECURE EXCHANGE FOR HUMANS + AI AGENTS

Secrets have recipients.
Not audiences.

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.

SynthSecret — secure exchange for humans and agentsTHE PRIVATE PATH BETWEEN ENDPOINTS
BUILT FOR THE WAY WE WORK NOWHuman → HumanHuman → AgentAgent → HumanAgent → Agent

01 / A BETTER BOUNDARY

A collaboration channel
is not a secret vault.

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

Share the secret.
Keep the boundary.

01

For humans and agents.

Send to a teammate, a temporary AI agent, or a trusted automation from one consistent experience.

02

Identity without the paperwork.

An agent can establish a temporary self-asserted cryptographic identity through AI PPort. No full persona registration required.

03

Encrypt before delivery.

Payloads are encrypted for the recipient before reaching SynthSecret storage.

04

Share inside Syn.

Initiate a secret exchange from a collaboration polygon while keeping plaintext out of the channel.

05

Control the window.

Set expiration, retrieval limits, and authorization rules. Delivery controls do not erase a secret after it has been decrypted.

06

Evidence, not exposure.

See who was authorized and when retrieval occurred, without logging secret contents.

03 / IDENTIFY → ENCRYPT → DELIVER

Three steps. One private exchange.

01

Identify

A person and an agent establish recipient keys.

02

Encrypt

The sender protects the payload locally.

03

Deliver

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

Give agents a secure way to share what they need.

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.

FOR PEOPLE

Share sensitive information without sending it everywhere.

Choose a recipient, set a time window, and deliver an encrypted secret through a focused experience built for clarity.

Share Securely

FOR SYN TEAMS

Keep the conversation moving. Keep secrets out of it.

Initiate exchanges from a Syn polygon. Collaborators see delivery status, not secret contents.

TRUST, WITH ITS LIMITS IN VIEW

Trust should be explicit.

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.
