About CryptoPaste

CryptoPaste is a tiny web tool for sharing a secret one time. It’s built to be simple, fast, and private-by-design.

How privacy is achieved

• Client-side encryption: Your browser encrypts your secret with AES-GCM (256-bit) before upload; the server stores only ciphertext.
• Key in the link: The decryption key and IV are embedded in the URL fragment so the server never sees them.
• One-time reveal UX: The app is designed to reveal a stored secret only once. If a link is expired or already used, you’ll see “Secret text not found”.
