Nothing is more frustrating to the sender and receiver than to exchange messages that can’t be decrypted. It’s a waste of time and effort, too.
If you lose your key or your passphrase, revoke your key as soon as possible. Key servers won’t always update this information immediately, so you should also notify the people you correspond with the most. Include your new key (in ASCII format) in your message so those people won’t have to search key servers for your new key.
