In every case, the command which +is about to create an object or transaction determines a payload from that, +calls gpg to obtain a detached signature for the payload (`gpg -bsa`) and +embeds the signature into the object or transaction. + +Signatures always begin with `-----BEGIN PGP SIGNATURE-----` +and end with `-----END PGP SIGNATURE-----`, unless gpg is told to +produce RFC1991 signatures which use `MESSAGE` instead of `SIGNATURE`. + +The signed payload and the way the signature is embedded depends +on the type of the object resp. transaction. |
