which file is Kgpg's  "password-store"  and when and how to set a password for it?

why do they not use KWALLETMANAGER as one would expect from a KDE app.


upon encryption of a file , I do infact see "another dialog box", asking for password and whether to
store that passwd in a "password-store" - for which another password is required.

so you deal with 2 passwords here, already leading to confusion.

But of course, Kgpg breaks and it is impossible to ever make use of said "password-store". 
And that  password-store is not KWALLETMANAGER, it appears. Cannot be in firefox either.

Then again, it might be, since exactly zero information is given anywhere in KDE about 
exactly which password-store that is, and which it is not. 

The Kgpg manual refers to gpg but about symmetric encryption. But the gpg
people just ignore this foreign reference. Of course, those doing gpg-proper
documentation could not care less about filling the gaping gaps in the GUIs docs.

I looked into the source code but that is tricky.
