Ftps/Tls awareness in Authenticator & StorageBackend

[jrouaix]

Hi, thank you again for this great lib !

Once Ftps configured and working, but FtpsRequired::None set ...

I'd like now to be able to know at runtime if the end users did actually use the secure way.

How could I get this information when Authenticator::authenticate is called (or any other function of the StorageBackend trait.

Do you have any idea on how to achieve this ?

Hi @jrouaix this sounds like something very useful to add to the Authenticator trait. I will consider adding it.

@jrouaix please see if #551 solves it for you.

Authenticator::authenticate can now know whether the FTP command channel is in TLS or plaintext mode.

What was you use case for having this information in the StorageBackend trait?
