RSA Encryption

I'm trying to find some easy-to-follow RSA key-generation, encryption/decryption examples.

What I've found are

http://software.intel.com/en-us/node/503498

and

http://software.intel.com/en-us/node/503457

Firstly, I'm not sure why (for example)

// Q prime factor
BigNumber    Q("0xC97FB1F027F453F6341233EAAAD1D9353F6C42D08866B1D05A0F2035028B9D86""9840B41666B42E92EA0DA3B43204B5CFCE3352524D0416A5A441E700AF461503");

This appear to be constants -- I'm assuming that these values are created by the RSA key generation procedure?

I can't get the samples to build as they are on the Intel site (I'm using IPP 8.1 on Windows FYI). I get the following errors:

error C2660: 'ippsPrimeGen' : function does not take 1 arguments

      IppsPrimeState* pPrimeG = ippsPrimeGen(P.BitSize());

and

1>rsa.cpp(83): error C3861: 'deletePrimeGen': identifier not found

      deletePrimeGen(pPrimeG);

Am I using the right samples for 8.1?

Are there better examples available -- I'm trying to find a good example that shows the end-to-end process or creating private/public key, using keys for encyption and decryption...

Any pointers greatly appreciated.
