scram_verify_server

hyperdb_api_core::client::auth

Function scram_verify_server 

Source 
pub fn scram_verify_server(state: AuthState, server_final: &[u8]) -> Result<()>
Expand description

Verifies the server-final message.

This function consumes the AuthState, ensuring all sensitive cryptographic material is zeroized after verification completes.

§Errors

Returns Error (auth) when:

  • server_final is not valid UTF-8.
  • The payload is missing the v= server-signature prefix.
  • The server signature cannot be base64-decoded.
  • The SCRAM state is incomplete (missing AuthState::server_key or AuthState::auth_message), indicating the caller did not run scram_client_final first.
  • The computed server signature does not match the one provided by the server (indicates the server does not know the user’s password).
