True Zero-Knowledge Privacy
When you submit a secret on VanishShare, your browser generates a 256-bit AES key and encrypts both text and files prior to dispatch. The host never sees plaintext.
Privnote was built over a decade ago. VanishShare brings next-generation client-side encryption, encrypted file transfers, and two-factor recipient verification.
