Hey there,
I'm facing a problem with pgp signing when using a Key that has a Subkey. It looks like VC uses both keys to sign (or actually signing it twice).
Please see the subkeys details. The Primary is set to certify and sign where the subkey is for encryption.
I expect that VC will pick up only Primary Key to sign the file. Unfortunately what VC does is it signs with PK first and then do the same for subkey.
