Method Detail

lookupDomainParameters

public static NamedECDomainParameters lookupDomainParameters(ASN1ObjectIdentifier paramOid)

Retrieve an EC based domain parameter by OID. A custom curve will be returned if one is available.

Parameters:

paramOid - object identifier for the domain parameters.

Returns:

the matching domain parameters if found, null otherwise.

lookupDomainParameters

public static NamedECDomainParameters lookupDomainParameters(ECDomainParametersID paramID)

Retrieve an EC based domain parameter by parameter ID. A custom curve will be returned if one is available.

Parameters:

paramID - identifier for the domain parameters.

Returns:

the matching domain parameters if found, null otherwise.

lookupOID

public static ASN1ObjectIdentifier lookupOID(ECDomainParameters domainParameters)
