SSH RSA DSA KEYS

Question:

RSA Keys are used for encryption and signing, but DSA keys are used
for just signing?

Why when you create keys under fedora does it create both? Why would
you choose DSA over RSA?

Just looking for some clear consise clarifiction on this topic.

thanks much!

Are you concerned with host keys, or with personal keys used for
public key authentication?

As far as I know, both RSA and DSA host keys are generated.

For personal keys, what is created depends on your command. Normally
you would choose one of the two. Your choice might depend on what is
acceptable to the hosts to which you connect.
