Re: [PATCH] verify: search keyid in hashed signature subpackets

Was preparing test data for the above patch. I wanted to reuse files
and keys in tests/file_filter. There are two files: keys and
I assumed first one is private key, while the other one is public.
However, it seems that keys is public as well. Is the test private key
for this public key available?
