What one does is to associate new email addresses over time to an existing 
key. This doesn't really "change the key". It just associates more mail 
addresses to that key. I'll try to post more on how that is done, tomorrow. 
That way, the same key can be used for a very long time (until, for example, 
one has reason to suspect or know the key has been compromised).

Oh. Well, without the passphrase one the keys are useless and one must 
generate a new set of keys.

Here is evidence of multiple mail addresses for one key...

The jpeg is most useful if it is a mug shot as it helps people remember and 
associate names with faces.

Crypto is a kick!
