signature property
The raw content of the signature, as output by GNU Privacy Guard (GPG) or equivalent.
Since this message only supports attached signatures, the payload that was
signed must be attached. While the signature format supported is dependent
on the verification implementation, currently only ASCII-armored
(--armor to gpg), non-clearsigned (--sign rather than --clearsign to
gpg) are supported. Concretely, gpg --sign --armor --output=signature.gpg payload.json will create the signature content expected in this field in
signature.gpg for the payload.json attestation payload.
Required.
Implementation
