Subject: [PATCH] signing plugin: use SHA512 instead of SHA1 when signing
 artifacts

PGP signs a digest, so MITM is still possible provided an attacker can update
the artifact in such a way that its SHA1 is intact.

Relevant article is https://medium.com/@jonathan.leitschuh/many-of-these-gpg-signatures-are-signed-with-sha-1-which-is-vulnerable-to-a-second-preimage-attack-67104d827930
