curveB	Elliptic Curve coefficient b
curveBLen	Elliptic Curve coefficient b length
curveSeed	Seed (optional may be NULL)
curveSeedLen	Seed length
baseX	Elliptic Curve point X coord
baseXLen	Elliptic Curve point X coord length
baseY	Elliptic Curve point Y coord
baseYLen	Elliptic Curve point Y coord length
bpOrder	Order n of the Base Point
bpOrderLen	Order n of the Base Point length
cofactor	The integer h = #E(Fq)/n (optional)
cofactorLen	h length
result	Resultant Encoding (length prediction supported if NULL)
resultLen	Buffer len/Length of resultant encoding
Return	Status of operation. CKR_OK if ok
