public ECNamedCurveTable()

Method Detail

getByName

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

return a X9ECParameters object representing the passed in named curve. The routine returns null if the curve is not present.

Parameters:

name - the name of the curve requested

Returns:

an X9ECParameters object or null if the curve is not available.

getByNameLazy

public static X9ECParametersHolder getByNameLazy(java.lang.String name)

getOID

public static ASN1ObjectIdentifier 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(ASN1ObjectIdentifier oid)

return a X9ECParameters object representing the passed in named curve.

Parameters:

oid - the object id of the curve requested

Returns:

a standard name for the curve.

getByOID

public static X9ECParameters getByOID(ASN1ObjectIdentifier oid)

return a X9ECParameters object representing the passed in named curve.

Parameters:

oid - the object id of the curve requested

Returns:

an X9ECParameters object or null if the curve is not available.

getByOIDLazy

public static X9ECParametersHolder getByOIDLazy(ASN1ObjectIdentifier oid)

getNames

public static java.util.Enumeration getNames()

return an enumeration of the names of the available curves.

Returns:

an enumeration of the names of the available curves.
