I've uploaded my public key and received the PGP message.
When I try to decrypt it fails with an error message:
Could not determine whether this is an S/MIME or an OpenPGP signature/ciphertext - maybe it is neither ciphertext nor a signature?
If I encrypt a message and email to another email address I can decrypt that message with no problems.
It looks like the line breaks are possibly being removed? Not really sure but the format of the message I can't decrypt looks somewhat different.
