I wanted to find out how hard it is to manipulate the @SeedSigner

. It was easy as expected. Never give it out of hand! Simple swap to a manipulated sd-card and it logs your seed to it. Later the attacker can collect the sd-card and get your seed words.

Total lines added to the code are six.

Needless to say, it writes the seed also to sd-card if you scan your backup seed.
