Hello,

I have a few questions, please.

 - Are all dsa and rsa keys in base64 format?

 - Can the type (dsa or rsa) be gleaned from the key itself,
   i.e. just from the base64 characters?

 - What is this format:
   1024 35 13346646368<snip many,many characters>055347 <username@isp.com>
   It can't be base64 because it's only digits...

 - Are public keys supposed to be generated on the client side, or can they
   be generated anywhere, as long as the public and private keys are put
   into their proper locations (id_dsa client side, authorized_keys2 server
   side, etc...) ?

Any assistance would be appreciated.
