RSA usage

[xwl]

I have this chart flow in my mind:

1. ippsRSAGenerate(E) => get N, D
2. run ippsRSAEncrypt(), ippsRSADecrypt() with previous N, E, D.

My question is that ippsRSAGenerate() requires the parameter:

IppsRSAState* pCtx,

but IppStatus ippsRSAInit(int nBitsN, int nBitsP, IppRSAKeyType flag,
IppsRSAState* pCtx); requires me to provide the "flag" parameter, either public or private. I'm not sure which one I should choose?

Our expert recomendation is to

Choose theflag for private operation in Init function.
