Repo with test cases for covert content attacks

[Sebastian Schinzel]

Dear all,

Jens Müller just gave a talk at DEFCON about Covert Content Attacks
against S/MIME and OpenPGP encryption and digital signatures in the
email context. He just published the PoC emails that he used in the talk
and they might be useful for further testing.

This is the paper describing the attacks from April 2019:

Best,
