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

handler The 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.
