I just generated a revocation certificate for my key. Unfortunately I don't fully understand the concept. Here are my questions:
How exactly am I supposed to use it?
Suppose for example that my private key gets compromised.
What exactly I am gonna do with my revocation certificate?
For instance, send an e-mail to all my acquaintances saying "Look, private key compromised, here is the revocation certificate?" (Why not just "Look, private key compromised."?)
Should I publish the revocation certificate on my website, in case the private key gets compromised?
If I re-run the same command in GnuPG, will I get a different revocation certificate? Or does it strictly depend on the private key only, so that given the private key one and only one revocation certificate is possible?
