Constructors

this this(CurveGFp curve, PointGFp base_point, BigInt order, BigInt cofactor, string oid): Construct Domain paramers from specified parameters
this this(Vector!ubyte ber_data): Decode a BER encoded ECC domain parameter set
this this(OID domain_oid): Create an EC domain by OID (or throw if unknown)
this this(string pem_or_oid): Create an EC domain from PEM encoding (as from PEM_encode), or from an OID name (eg "secp256r1", or "1.2.840.10045.3.1.7")
