SECDEVTOOL-OMAPL138C6748: Module RSA in OpenSSL

Part Number:SECDEVTOOL-OMAPL138C6748

I'm looking for RSA cryptography in link below, it's inside OpenSSL:

It have many module cryptography, this is complex and redundancy too. So i want to use only module RSA, how can I extract only module RSA from OpenSSL or where i can find RSA source for TI's device.

I use platform OMAPL138 LCDK.

Thanks in advanced !
