documentation on advanced features/topics

[Gregor Zattler]

Hi,

until now i'm using gpg as a pgp2.6.3 replacement. My knowlegde about
how to use and what to avoid in using pgp 2.6 is fairly good (i think).

Now it comes to generating a new keypair (instead of my old pgp263
key) and im searching for advanced documentation about 

subkeys, 

key preferences, 

algorithms 

and the like.


Thanks for helping,
Gregor
