Sorry, but not working. Here are the logs: https://gist.github.com/RufusJWB/9d287f887f16c0e4732ab59a4f82bb0c

@RufusJWB thanks for report and log, I will investigate it along with the recent changes to minidriver.

I have found some additional issues

• the return value of depadding function should be non-negative in good case
• the inversion after depadding is refactored, it should be touching only bytes from decrypted message now.

I can confirm, the bug is fixed now.

@RufusJWB Thanks for testing!

As we are not Windows developers, is there somebody from you reporting this issue, able to put together some (ideally automated) tests of the minidriver to avoid such issues in the future?

Sorry, but not me.

Or at least be able to run some manual tests before the release?

Yes, I'd be happy to support. Ideally, you would provide a WinGet package with the pre-releases. I once opened an issue #2699 about this, which we might want to re-visit.

It looks like there is (outdated) opensc 0.23.0 as for today:

created after your request in microsoft/winget-pkgs#123939 so maybe just opening another to update would get it updated (or just opening a PR to update it) -- they just point out to our installers in github releases which do not look that complicated.

I wasn't aware, that this topic was picked up by someone at Microsoft. Great news. I'll follow up with them.

Thank you!
