Hi,

I have the same error with:

DllDate: May 25 2017 ChilkatVersion: 9.5.0.68 UnlockPrefix: XXXXXX Architecture: Little Endian; 64-bit Language: .NET 4.0 / x64

If you need, I can provide a RSASSA-PSS Cert.

I found the problem and made the fix. This new build should fix it:

Hi,

I have the same error with chilkat ActiveX (ChilkatVersion: 9.5.0.68 Architecture: Little Endian; 32-bit Language: ActiveX)

Is this problem fixed in an ActiveX build?

Thank you
