--- Comment #1 from Omega Software info@winomega.com --- Created attachment 57272 --> https://bugs.winehq.org/attachment.cgi?id=57272 WINEDEBUG=+crypt trace
Attaching a trace -- hand-edited to remove potentially sensible information (all chunks of blobs in binary or hex format have been replaced by ***REMOVED***)
The following line:
warn:crypt:CryptQueryObject unimplemented for types 00001000
makes me suspect PFX/P12 support simply isn't implemented, as I can import PEM (base64-encoded DER) public keys just fine.
