[LUG] PGP / GPG subkeys and IDs

 

I currently use GPG but currently have two keys (on two seperate email
addresses). In reading up on this, I discover
- Have two keys keys is crazy (if nothing else signing emails is already
  driving me crazy)
- The current sha1 (?) hash has been broken and therefore should be
  upgraded. The easiest way to do this is to add a subkey
- To have two seperate email addresses using PGP the easiest way is to
  add an ID

So therefore I should:
- Added an ID to my master key (email address henry.bremridge@xxxxxxxxx
  and hb@xxxxxxxxxxxxxxxx)
- Add a DSA subkey to sign emails
- Add a seperate Elgagal subkey to process encrypted emails.
(There was an option to use RSA but this is apparently only for US use?)

Could someone please confirm if my understanding is right, as if so I
will be changing my details with the LUG so I can use PGP.


Thanks
