7.4.2. Publish your public key on a keyserver

By far, the easiest way to let the world know your public key is to publish it on

the public keyserver network, a global database of keys.

Some people believe it's a bad idea to use a keyserver, because spammers

search them for email addresses. While this is true, the amount of spam you

risk to receive by doing this is quite small: you receive roughly ten times more

spam when you put your email address on a web page or post a message on

the Usenet.

In order to publish your key, click on your key and select Keyserver → Upload

public keys. You will be given a choice of keyservers; pool.sks-keyservers.net

is the one Enigmail uses by default. Major keyservers periodically synchronize

themselves.

Click on Ok and wait for your key to be uploaded. Your key is now published on

the Internet for anyone to find.

Once a key is uploaded to a keyserver it will stay there forever.

There is no way to delete a key from a keyserver. You can disable the

key by revoking it, but anyone in the world will still be able to view all

your user IDs (your name and email addresses), including your

PhotoID. If you have privacy concerns about this, don't upload your

key in the first place.

7.5. Revoking your key pair

In the unfortunate event that you lose your key pair or feel it has been

compromised, you should revoke it.

You can use the revocation certificate that you generated in advance (or at least

you should have done so) to invalidate the key pair. Select File → Import keys

from file from the Key Management window and choose the ASC file containing

your revocation certificate.

If you did not generate the revocation certificate in advance, you can revoke the

key on the fly, provided that you still have your key pair and you remember your

passphrase. To do so, select the key pair you want to revoke and click on Edit
