System.IO.IOException : unknown object in stream SecretSubkey

[haegg78]

Version used: 6.5.1

I have used the examples from https://www.nuget.org/packages/PgpCore/#readme-body-tab to be see if I can use the functionality that is provided.

I have then created a case where I generate a new key using GenerateKey (https://www.nuget.org/packages/PgpCore/#generate-key) and then encrypt and sign a file using the first example (https://www.nuget.org/packages/PgpCore/#encrypt-and-sign) and finally I try to decrypt and verify the encrypted and signed file using the first example (https://www.nuget.org/packages/PgpCore/#decrypt-and-verify).

If I use gpg to decrypt and verify the encrypted and signed payload then everything works and gpg reports the right signature etc. But when I use the example code then I get this exception:

I have tried to use both keys created using gpg and using PgpCore with the same result.

What is the reason for this error being thrown?

[mattosaurus]

Hi, generaly this error is due to using the wrong keys, e.g. a public key in place of a private key.

I'd suggest looking at the tests for working examples.

https://github.com/mattosaurus/PgpCore/blob/master/PgpCore.Tests/UnitTests/Decrypt/DecryptAsync.File.cs

It's also possible that the readme examples are incorrect so if that's the case please feel free to submitt a PR correcting them.

If you can provide an example script I can take a look at that as well.
