- * This class implements encoding and decoding of Elliptic Curve parameters

- *
- * However, only named curves are currently supported.
- *
- * ASN.1 from RFC 3279 follows. Note that X9.62 (2005) has added some additional
- * options.
- *
- * <pre>
- * EcpkParameters ::= CHOICE {
- * ecParameters ECParameters,
- * namedCurve OBJECT IDENTIFIER,
- * implicitlyCA NULL }
- *
- * ECParameters ::= SEQUENCE {
- * version ECPVer, -- version is always 1
- * fieldID FieldID, -- identifies the finite field over
- * -- which the curve is defined
- * curve Curve, -- coefficients a and b of the
- * -- elliptic curve
- * base ECPoint, -- specifies the base point P
- * -- on the elliptic curve
- * order INTEGER, -- the order n of the base point
- * cofactor INTEGER OPTIONAL -- The integer h = #E(Fq)/n
