Share sensitive text safely

CryptBin encrypts your content directly in the browser before it is sent anywhere. The decryption key stays in the URL fragment, so the server can store and deliver the paste without reading it.

It is built for short-lived secrets and private snippets. You can set expiration rules, enable burn-after-read, and share a single secure link with confidence.

Get started by creating a paste, choosing your retention options, and sharing the generated secure URL.

Create Secure Link

Write sensitive text, encrypt it in-browser, and generate a secure share URL.

Expiration Controls

Set when a paste expires so shared secrets only live as long as needed.

Burn After Read

Make links self-destruct after first access for one-time sensitive sharing.
