Hey all,

I'm having issues when decrypting messages encrypted by Thunderbird with
the following exception:

Org.BouncyCastle.Cms.CmsException: Unexpected object reading content. --->
System.InvalidCastException: Unable to cast object of type
'Org.BouncyCastle.Asn1.DerApplicationSpecific' to type

Any ideas on this?
