The following patches will allow PGP 2.6.3ia to generate and process
RSA keys up to 4,096 bits in length.

The old warning about PGP 2.6.3ia not being for use in the USA has
also been removed, now that the RSA patent has expired.

These changes are effective ONLY if the source is NOT compiled with
the "-DUSA" option.

I believe these patches are bug-free, but I accept no liability; use
the patched version at your own risk.

The PGP 2.6.3ia source can be found on www.pgpi.org (the "International
PGP" site run by Ståle Schumacher in Norway).  It's called "2.6.3i"
on this site, but it includes a set of bug fixes from March 1996 which
are described at:  http://www.pgpi.org/files/pgp263ia-patch.shtml
