Direct Known Subclasses:

FlexiCoreProvider, FlexiECProvider, FlexiNFProvider, FlexiPQCProvider

public abstract class FlexiProvider

extends java.security.Provider

This class is the base class for all providers which are part of the FlexiProvider library. It contains registration methods which provide existence and type checking of the registered classes as well as an improved alias handling.

Constructor Detail

FlexiProvider

protected FlexiProvider(java.lang.String name,
                        double version,
                        java.lang.String info)

Construct a provider with the specified name, version number, and provider information.

Parameters:

name - the provider name

version - the provider version number

info - a description of the provider and its services

Method Detail

add

protected void add(int type,
                   java.lang.Class algClass,
                   java.lang.String algName)
            throws RegistrationException

Register an algorithm of the given type under the given name.

Parameters:

type - the algorithm type

algClass - the class implementing the algorithm

algName - the name for the algorithm

Throws:

RegistrationException - if the expected and actual algorithm types do not match or an algorithm is already registered under the given name.

add

protected void add(int type,
                   java.lang.Class algClass,
                   java.lang.String[] algNames)
            throws RegistrationException

Register an algorithm of the given type under the given names.

Parameters:

type - the algorithm type

algClass - the class implementing the algorithm

algNames - the names for the algorithm

Throws:

RegistrationException - if the expected and actual algorithm types do not match or an algorithm is already registered under one of the given names.

addReverseOID

protected void addReverseOID(int type,
                             java.lang.String algName,
                             java.lang.String oid)
                      throws RegistrationException

Assign an OID for the reverse mapping (OID -> algorithm name) to an algorithm. Check whether the algorithm the OID is assigned to is registered.

Parameters:

type - the algorithm type

algName - the algorithm name

oid - the OID used for reverse mapping

Throws:

RegistrationException - if the algorithm the OID is assigned to is not registered.
