Encrypted sharing for developers and security-minded teams

Cryptbin is encrypted sharing with zero knowledge on the server: your content is encrypted in the browser before upload. The decryption key lives only in the URL fragment, so the server stores ciphertext (not plaintext) and never receives the key over HTTP.

Use it for API keys, configs, diffs, and snippets you need to share quickly without trusting the host with readable data. Pick syntax highlighting for readers, set expiry or burn after read, and optional vault recovery when you are signed in.

Create a text or file link, copy the secure URL, and share it through the channel you already use, knowing the payload stays encrypted at rest.
