This package implements OPAQUE, an asymmetric password-authenticated key exchange protocol that is secure against pre-computation attacks. It enables a client to authenticate to a server without ever revealing its password to the server.
This implementation is developed by one of the authors of the RFC Internet Draft. The main branch is in sync with the latest developments of the draft, and the releases correspond to the official draft versions.
OPAQUE is an aPAKE that is secure against pre-computation attacks. OPAQUE provides forward secrecy with respect to password leakage while also hiding the password from the server, even during password registration. OPAQUE allows applications to increase the difficulty of offline dictionary attacks via iterated hashing or other key stretching schemes. OPAQUE is also extensible, allowing clients to safely store and retrieve arbitrary application data on servers using only their password.

- OPAQUE is used in WhatsApp to enable end-to-end encrypted backups.
