I get this from your mail: # gpg: Signature made Tue Dec 25 11:24:13 2018 CET using DSA key ID 5F093FF8 # gpg: Can't check signature: public key not found I did not manage to find your key on key servers, but there is enough information here: DSA. https://en.wikipedia.org/wiki/Digital_Signature_Algorithm It cannot be used for encrypting, only for signing, that is because of its mathematical design. On the contrary, for example, a RSA key can be used for both signing and encrypting. Regards, -- Nicolas George
