Hello all, I'm new at this list.

I'm using OpenPGP with GPG since some years ago, I'm using as "usual
way": a pair of keys copying from one device to other.

I'm interested in subkeys and offline master key, I'd like to migrate
mine pairs but in "minimal effort": I'd like to no reupload any public
key to any server, I have all mine master keys for Certify and Sign,
but I'm afraid it not would be possible, I'd like to have master keys
only with Certify usage, but when I add a subkey for Sign, GPG signs
with new subkey and receipts can't verify because don't have new public
subkey.


Is it possible "extract" Sign usage from master key an put it into a
subkey with the same ID and fingerprint? I'm think no.

This email is to verify that, indeed, it is not possible.

Regards and thanks in advanced, I hope I've explained right.
