Encrypted notes for developers and security-minded teams

CryptBin is zero-knowledge encrypted note sharing: 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 note, copy the secure link, and share it through the channel you already use—knowing the payload stays encrypted at rest.
