Text and files
Share notes or upload a file up to 2 MB. Both are encrypted locally before upload.
Features
Security that stays out of the way
SecureVault is designed for quick, private handoffs — passwords, tokens, notes, and files that should not live forever in chat history.
Browser-side encryption
AES-256-GCM via the Web Crypto API. Plaintext is never uploaded.
Fragment keys
Decryption material lives after # in the URL, so it is not sent in HTTP requests.
Passphrase layer
Optional PBKDF2 protection for an extra secret only you and the recipient know.
Burn after reading
Configurable view limits and lifetimes permanently delete ciphertext from storage.
