Where was this topic discussed before?
Can you please provide a reference.
AFAIK there are no provisions for “secrets” in OBS or specifically the Sailfish-OBS (which uses an older OBS release).
Have you heard of any or why are you bringing up this topic here (while sounding as if it has been discussed elsewhere, but not referencing this discussion)?
More specifically: Have you researched that OBS or a OBS-plugin provides some kind of “secret handling”? If so, please provide the sources and results of your research, then one (technically interested people or sailors) can look into that.
