This is still very much a work in progress, but we found an innovative way

OpenBSD-ifying it.<p>

OpenBSD-ifying it. We will get around the USA-based RSA patent by providing

an easy way to automatically download and install a RSA-enabled package

containing shared library versions of libcrypto and libss. These packages

are based on OpenSSL. People living outside the USA can freely use the

RSA patented code, while people inside the USA can freely use it for

non-commercial purposes. It appears as if companies inside the USA can

use the RSA libraries too, as long as RSA is not used in a profit generating

role.<p>

We get around the US-based RSA patent by letting end users
