saltpack encryption for keybase users, how?

Hi all,

i wonder how saltpack (python code) users (not using keybase) can use an encryption key from keybase? When i use saltpack for encryption it gives no erros but when decrypting with keybase decrypt -i file.txt i get the following error:

Decryption failed; it was encrypted for 1 hidden receivers, which may or may not you
▶ ERROR decrypt error: no suitable device key found

my second question about saltpack signatures: when signing with saltpack keybase shows verified and the key id, but saltpack python code does not. Would it be possible that saltpack python code could show this info too, in an update?

Best regards
Stefan

Start by reproducing the saltpack Python encryption and signing commands, then compare their outputs with `keybase decrypt -i file.txt` and Keybase's displayed signature information. Determine whether the requested behavior is a compatibility issue or a new feature; done means documenting or implementing a clear way for non-Keybase saltpack users to use Keybase keys and see signer information.
