Hi,
We have an issue with mail decryption after updating from ChilkatDotNet2 to ChilkatDotNet4.
We had used Chilkat2 (9.4.1) on Framework 2.0 and all worked fine. Now we upgraded to ChilkatDotNet45 (9.5.0.56) and mime.DecryptUsingPfxFile() does not work anymore.
Same code on the same email and the same certificate, different results.

Having Verbose logging switched on below is all I get on 9.5.0.56:

ChilkatLog:

    Failed.
  --DecryptUsingPfxFile
--ChilkatLog.

When using ChilkatDotNet2.dll in version 9.4.1 I have a success on the decrypt and the following Log content:
