How it works
- AES-GCM 256-bit encryption in the browser
- Without password: random key in URL fragment (#)
- With password: key derived via PBKDF2 (200k iterations)
- The server gets nothing past the fragment
Limits and storage
- Maximum 10,000 characters
- Expiration enforced server-side via Redis TTL
- Burn-after-read deletes paste on first view
- No sign-up, zero-knowledge encryption
