Crash when using EV Certificate using a Yubikey (SSL.com)

[burgerbecky]

I am using an EV Code signing certificate that only exists in a Yubikey, so there's no .pfx file so I can't use vsixsigntool. This tool almost works, but it crashes with the stack dump. I've also included the offending command line

d:\oldeskuul\tools\visualstudio\glsl\bin>OpenVsixSignTool sign --sha1 [redacted] --timestamp http://ts.ssl.com -ta sha256 -fd sha256 glsl-vs2022.vsix

FYI, signtool works just fine with MSI files.
