This parameter should rather be

                           virSecretUsageType usageType

I didn't really get the "encFmt" name, but it's just a minor issue
compared to the way the error message is composed here. This results in
an untranslatable string. I think returning a generic error about
unsupported encrypted secrets would be good enough.
