This new option can be used to detect ROCA affected keys. To scan an
entire keyring and print the affected fingerprints use this:
gpg -k --with-key-screening --with-colons | gawk -F: \
'$1~/pub|sub|sec|ssb|crt/ && $18~/\<6001\>/ {found=1;next};
$1=="fpr" && found {print $10}; {found=0}'
The same works for gpgsm. Note that we need gawk due to the "\<" in
the r.e.
