staticprotected

Fast quasi-reduction modulo P = 2^s - R, with R about 33 bits, used by the Koblitz curves. Write N as A0 + 2^224 A1, return A0 + R* A1. Actually do two passes, since R is big.

◆ ModP()

virtual HRESULT GrayLib::cECPGroupDef::ModP ( OUT cBigInteger & N ) const

inlinevirtual

optimized function for fast reduction mod P. e.g. Mod_x25519. replaces N.InitModulusU(N, this->m_P); P is hard coded/assumed/known.
