Some Clients are reporting:

Probably the same as https://github.com/adamhathcock/sharpcompress/issues/743

I encountered this error and was expecting a SharpCompress.Common.CryptographicException but got also a null reference.

Guess it is a bit inconvenient but please build sharpcompress from master branch and test with that, I don't think we have released the change that got merged for this issue.
