As I already told here, PC2 is patented and anyway obsolete.  We won't
include it.  Furthermore importing a 40 bit RC2 encoded certificate
is really silly as this can be broken trivially and it must be assumed
that such a certificate has already ben compromised.

There is nothing like public domain in most European countries and
such the legel status of such an implementation might get us in trouble
later on.
