[openssl-dev] [openssl.org #4246] OpenSSL-1.1-pre2 openssl req fails to use engine

[deengert@gmail.com via RT]

Yes,  #458  is similar but for the pkeyutl.c

I would have changed:

{"keyform", OPT_KEYFORM, 'F', "Private key format - default PEM"},
to
{"keyform", OPT_KEYFORM, 'f', "Private key format - default PEM"},

The patch also adds an additional parameter,
{"engine_impl", OPT_ENGINE_IMPL, '-', "Also use engine given by -engine for crypto operations"},

I would ask the author about the engine_impl . It looks to me that to keep the previous behavior of the command
one would need to add this option if an engine is used. IIt could also be an issue with the ordering
of the parameters, or to try and not use the engine when the public key is used.
(I could be wrong on this.)

The author is also  active on the OpenSC list trying to use EC with the OpenSC engine.
