Cryptbin

What it does

Zero-knowledge encrypted notes for developers—share API keys, configs, and code with client-side encryption and optional syntax highlighting.

Encrypt env vars, tokens, and snippets in your browser, then share a link. The server stores ciphertext only — the decryption key stays in the URL fragment. Drop an API key, token, or config snippet into the composer. Cryptbin encrypts in your browser before anything is uploaded. Share API keys, configs, and snippets without handing plaintext to the server. The server stores ciphertext only. The key stays in the URL fragment. Share, collect, or decrypt — three paths, same client-side encryption. Encrypt text or a file in the browser, then send one link. The key stays in the URL fragment. Use encrypted forms or structured secrets when you need responses or key–value packs locked to you.…from cryptbin.com
