implications of subkeys?
Fri Mar 1 16:36:01 2002
I was really thinking of 2 ELG sign/encrypt sub-keys instead of the 2 ELG
encrypt sub-keys and the 2 DSA sign sub keys. However, there was some note
about the ELG sign/encrypt being depreciated. I'm not sure what that really
means in this case but the dictionary definition implied this was a bad
The more comments I read, the closer I come to believing the best bet is a
key set for work and a totally separate key set for home. Or more
precisely, a personal set and a business set.
Now, it does appear to me that the default mechanism GPG uses to build the
keys (a DSA sign pair and an ELG encrypt pair as a sub-key) really does lend
itself to keeping the DSA around as long as possible while putting a life on
the ELG sub-keys.
However, if the authorities came and asked for my decrypting key, I'm not
sure I'd know how to pull only the ELG sub key (private piece) out to give
to them without also letting them have the DSA private key.
PS Thanks for everybody who has chipped in on this discussion as it sure
has increased my understanding of the black box.

Yes, but then you would have had two "keys" in the keyservers and on
