ssh-keygen and slogin oddity

[Patrick Eisenacher]

Corinna,

do you have any reference for this?

Unless this is something inherent in the ssh protocol or its 
implementation, which I'm not familiar with, I'm not aware that crypto 
systems based on discrete logarithms (DSA) are less secure than those 
based on factoring large integers (RSA).

FWIW:
- RSA verifies much faster than DSA, whereas DSA signs faster than RSA
- RSA can also be used for en-/decryption, whereas DSA can not
- RSA was patented in the USA, but the patent ran out in the meantime
- strong encryption crypto (eg RSA) was export restricted from the US, 
but this restriction was deregulated
