It is in general faster and there are OpenPGP implementations which only
support RSA (despite that the standard requires DSA and Elgamal).  The
drawback is that RSA signatures are larger than those made with DSA.
IIRC, we discussed that back then and you may find something in the
mailing list archives.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
