From: bshantz@spry.com [..] I never found out [...] what was decided in regards to the legal implications of a PGP functional DLL for Windows. If a PGP DLL were rewritten from scratch and placed in the public domain the only concern would be patent licensure. By rewriting, you've removed any sort of copyright issue. The only was you'd get an RSA license is to use RSAREF. That means that use of the DLL would be restricted to non-commercial use. You'd also need an IDEA license, but I suspect that if you're just doing something PGP compatible you'd be able to obtain that, especially since it would be non-commercial because of RSAREF. If you need commercial accessibility, you'd need licenses from RSADSI and Ascom-Tech. You could then give the DLL away, but RSADSI wants minimum royalties, so you'd be subsidizing the public. I don't know the situation with Ascom. Eric
