Hi,

Does anybody know if there is a GPL implementation of RSA verification for the Linux kernel?

I know DigSig, but is anything recent available?

Thanks,
Dmitry

In NCR [http://home.gna.org/cryptodev-linux/ncr.html] I've added RSA and DSA using the public domain libtommath/libtomcrypt. You could use them. The internal API for RSA is the libtomcrypt one.

Hi,

Indeed. Forgot about it. I even have that repo on my computer: newapi branch.

Thanks,

Dmitry

I wonder if such code can be integrated to Linux kernel.. It needs to be GPL..
Can this "F..G" license be converted to GPL...?

I see that there is new maintainer of libtomcrypt and such and uses this licence. This wasn't the case when I started working on that, thus my code is based on the last public domain one released by Tom (and is also pretty modified).
