Paste

ZeroBin-style encrypted paste stored entirely in your share link.

Client-side encryption

The paste is encrypted in your browser with AES-256-GCM. The ciphertext and key live inside the URL fragment so nothing is sent to the server. Share the link carefully.

Size: 0 bytes - Max 32 KB for share links.

If you set a passphrase you must share it separately. For larger payloads, use the Saf tool instead of paste links.

Share link

The link contains encrypted data and the key inside the fragment. Anyone with the link can decrypt it, plus the passphrase if you set one.

Ciphertext (debug)

Security model (30 seconds)

The paste is encrypted locally with AES-256-GCM. The ciphertext and key live in the URL fragment, so they are never sent to the server. If you add a passphrase, both the fragment key and passphrase are required to decrypt. No server-side secrets and no user tracking are used.
