RSA implementation?

RSA implementation?

[Julian Morrison]

Is there any GPL compatible Ada code out there that anyone knows of, that can
do RSA encryption?

Out of curiosity, what do you mean by "GPL compatible" ?

Isn't there a software patent from RSA Data Security Inc. for RSA
encryption? If this is true, there should not be any GPL implementation.

The patent expired last month.

It's a software licensing issue.  "GPL compatible" means "can be used
together with code released under the GPL".

The patent also only applied in the United States.

Are you certain Julian Morrison meant nothing more specific ?

Might it not have been "can be bound into an image with code licensed
under the GPL" or "can be invoked as a shareable image from code licensed
under the GPL" ?  In that latter sense, Windows NT is "GPL compatible".

MD5 is available from:
http://www.adapower.com/alg/Md5.html

I don't know if it meets your compatibility requirements though.

Thanks for the information; I was not aware of that MD5 implementation.

Although that implementation derives from RSA, the company,
the original poster wanted to get an implementation of RSA, the algorithm,
which is entirely different from MD5.

GPL compatible in this case means: I can use the package or whatever in creating a GPL'd Ada program. Preferably, as a
nice neat Ada package that I can bundle into the source code distribution and it will just "gnatmake".

MD5 is a secure hash (and an ancient, weak one). It's not RSA, although it was
made by the RSA company.
