Handling of empty secrets

[Andrey Borzenkov <arvidjaar gmail com>]

I try to sanitize handling of secrets in knetworkmanager. The main
issue I face - what to do with empty secrets and are they allowed at
all?

Random checking of upstream VPN plugins seems to indicate, that empty
secret is treated as missing secret. OTOH empty secret - while
probably insecure - could be valid?

So what are rules for handling of secrets in NM? Are empty secrets
allowed and are they distinguished from missing secrets?

Thank you!
