Hi there,

Someone has recently informed me that as RSA is a patented algorithm you
need to purchase a license to be legally allowed to use the RSA classes in
the .NET Framework in your application. Is this true???

Nak.
 
Cor,

Indeed, hello! Long time no chat. I got this email a few days ago and
thought it was complete crap, just wanted to clarify this. Any ideas?

BTW. Is Herfried still around? ;-)

Hi Nick,

Is your program using the framework or standard Api's for this (that was our
first very hard discussion).

:-))

I do not know exactly the answer, however I thought about it.
Therefore we keep it in this OT thread.

I saw this page from Microsoft.
http://www.microsoft.com/presspass/press/1996/aug96/Rsapr.asp

You saw I wrote express.
"Are you using"

This is always tricky stuff, however I think that in this kind of things it
is important to ask yourself "Is my client with my program using something
he has already bought by Microsoft (or another) or is it something I have
added?

When someone has bougt it already (even if it is for free) I think he has
not to pay for it another time.

However just my thoughts about this and of course not one cent or penny
guarantee

I don't know, but I assume that the .NET RSA classes are only wrappers
around Windows' CryptoAPI. There seem to be some threads about this
topic...

The Framework. :-)
