http://bugs.winehq.org/show_bug.cgi?id=60190 --- Comment #8 from Urias.Uhle@web.de --- Created attachment 81908 --> http://bugs.winehq.org/attachment.cgi?id=81908 claude-key-usage-analysis Thanks for looking into it. I can't really judge this myself, I don't know this part of wine well enough. I've attached an md file with what my Claude session worked out from the trace. Short version: you're right that the key never reaches CryptEncrypt or CryptDecrypt, but every PRIVATEKEYBLOB import is followed by a SIMPLEBLOB import into the same provider with hPubKey pointing at the key that was just installed as the key exchange key, and import_symmetric_key() decrypts that block with it. So the private key operation is inside CryptImportKey, not in a separate call. Either way, patching this is what made the problem go away in Autodesk Fusion. If you need any more traces or a smaller one narrowed down to a single round trip, just say so and I'll record it. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
