I've been a long-time list lurker, but these questions have finally
gotten me to pipe up. I know they're not directly Linux questions, but I
asked on the gnupg-users list and got ignored. Any and all help
appreciated.
I've just started using GPG and have the following questions:
What do the characters in the set "+.>^" mean during key generation?
Which are the times during key generation during which munging the
keyboard would have maximum effect? Is random data gathered only at the
beginning of the gen-key process, or all the way through?
How much longer does it take to encrypt/decrypt using a 4096 bit key
than a 1024 bit key? Am I right in thinking that it's only the session
key that gets encrypted with the 4096 key, so it shouldn't affect
encryption times too much?
By how much are the size of signatures affected?
Are these two factors the only reasons why keys > 2048 bits are not
recommended?
Please point me at TFMs as appropriate. I've looked at "The GNU Privacy
Handbook" and didn't find my answers there.
Thanks in advance,
