From commit https://github.com/Yubico/yubikey-manager/commit/9bf8f872c5bc81ee315dd14ee91b402c8555d64d, which is included in yubikey-manager 4.0.0 and later, it could use (and prefer) pkcs12 from dev-python/cryptography >= 2.5, on which it already depends. I'm suggesting to drop dev-python/pyopenssl dep, as dev-python/cryptography is already required, preferred, an there are no versions <2.5 in the portage tree.
