Detailed Description

Handler for combining a number of authentication handlers, where the failure of one of the handlers will retry with another handler.

For example when authorized keys fail, it can still fall back to a password.

Member Function Documentation

◆ Add()

void CombinedAuthenticationServerHandler::Add ( CombinedAuthenticationServerHandler::Handler &&  handler)

Add the given sub-handler to this handler, if the handler can be used (e.g.

there are authorized keys or there is a password).

Parameters
handlerThe handler to add.

Definition at line 397 of file network_crypto.cpp.

References handlers.

◆ CanBeUsed()

bool CombinedAuthenticationServerHandler::CanBeUsed ( ) const
overridevirtual

Checks whether this handler can be used with the current configuration.

For example when there is no password, the handler cannot be used.

Returns
True when this handler can be used.
