Bug#904685: diffoscope: RuntimeError when trying to extract an encrypted file (.bmp)

[Ricardo Gaviria]

Hi Chris,

Thanks for your response. Please find attached the culprit. I believe the
issue may lie with the fact that I am trying to diff an archive which
happens to be encrypted and requires a password.

I'm guessing encrypted archives could be ignored when diff'ing and flagged,
and possibly just diffing the fingerprint of the archive blob? Or what do
you suggest?

Thanks again,
Ricardo
