[libvirt] Authentication with virConnectAuthPtr

Hello all, I'll start using virConnectAuthPtr to handle the authentication proccess at the phyp driver I'm wrinting <https://www.redhat.com/archives/libvir-list/2009-April/msg00493.html> and I have some doubts in my mind: 1) What are the types of authentication that 'int *credtype' can hold? And who fills it with the information I'll need? 2) Once known the credential type, I need to use the function pointer 'virConnectAuthCallbackPtr cb' to get the information whatever it is, right? I mean, it can be a password, a pubkey or anything else, right? Is there a callback able to handle password or pubkeys? 3) And finally I'll be able to use the 'void *cbdata' to manage the authentication in my way. In my case, using libssh. In fact, in the end of the process, I'll just need a password or a key to get things working. There is no driver authenticatin agaist ssh channel, that's why I got so confused with this topic. I don't know if my thoughts are pretty clear here. But I would like to confirm the information 2 and 3, and check how 1 works. Could anyone help me?
