I've created a keypair with
Then I created a subkey only for sign. If I clearly understand the process I have now 3 pub/priv pairs. The master, one for encrypt and one for signing. I exported public keys with :
gpg --armor --export FINGERPRINT > pub.asc
Now I have a file which seems to contains only one public key, is it the master public key ? Does this pub key contains the others public keys ?
Because I'll sign with the third subkey I've created, so which public key do I need to upload on a keys-server ?
Thank's in advance for explanation.
