Method Detail

defineCurve

static void defineCurve(java.lang.String name,
                        DERObjectIdentifier oid,
                        X9ECParametersHolder holder)

getByName

public static X9ECParameters getByName(java.lang.String name)

getByOID

public static X9ECParameters getByOID(DERObjectIdentifier oid)

return the X9ECParameters object for the named curve represented by the passed in object identifier. Null if the curve isn't present.

Parameters:

oid - an object identifier representing a named curve, if present.

getOID

public static DERObjectIdentifier getOID(java.lang.String name)

return the object identifier signified by the passed in name. Null if there is no object identifier associated with name.

Returns:

the object identifier associated with name, if present.

getName

public static java.lang.String getName(DERObjectIdentifier oid)

return the named curve name represented by the given object identifier.

getNames

public static java.util.Enumeration getNames()

returns an enumeration containing the name strings for curves contained in this structure.

getOID

public static DERObjectIdentifier getOID(short curvesize,
                                         boolean twisted)
