Thanks for the link! But it's not really what i need.

Actually, i'm mainly preoccupated for the samsung (on which i lost the
passphrase). So, my question is: Is there a way to

a) establish if encryption is active or not?
b) to annulate the encryption (i think that might be possible for me,
als logged in user, since i presume the passphrase is somewhere stored
in the key; since i'm logging in automatically - as user.

TIA
