UserSessionVerifiers class
Session verifiers sent from user to server during authentication.
This data structure contains the information needed for the server to verify the user's identity and session key. It is generated after the user processes the server's challenge.
Usage:
- User creates this via User.getUserSessionVerifiers after processing challenge.
- User sends all three fields to server (e.g., via JSON serialization).
- Server uses these values to verify the user's identity and session key.
- If verification succeeds, server responds with a server session key verifier.
Security:
- The session key verifier (M1) proves the user knows the password without revealing it.
- The ephemeral public key (A) is safe to transmit over untrusted networks.
- Use erase to securely zero out the data when no longer needed.
Constructors
