Sendenv

Intro

Sendenv is a utility for securely sharing short-lived secrets such as environment variables and API keys. Secrets are encrypted in the user's browser so the service provider cannot read them. Shared secrets are delivered via links that expire after one hour by default and are usable only once, which limits exposure if a link is intercepted.

Key Features

• Client-side encryption: secrets are encrypted in the browser before being sent.
• Access limited to the recipient holding the correct link; the provider cannot read stored secrets.
• Default expiration of 1 hour, with example configurable intervals including 1 hour, 3 hours, 6 hours, 12 hours, and 24 hours.
• Single-use links: each link can be used only once.

Notes on limits: the short default lifetime and single-use behavior are deliberate security choices but may not suit workflows that need long-lived or reusable access.

Who this is for

• Senders who need to transfer environment variables, API keys, or other secrets to a specific recipient without leaving readable copies on the provider.
• Recipients who will retrieve a secret using a correct, single-use link before it expires.

If your workflow requires persistent links, team-level access controls, or documented pricing and integration details, those items are not shown in the available product information.
