Do DER enc of ECC Domain Parameters Prime

All integer values are variable length big endian numbers with optional leading zeros. Integer lengths are all in bytes.

Parameters

primeLen	Prime modulus len
curveA	Elliptic Curve coefficient a
curveALen	Elliptic Curve coefficient a length
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
