java.lang.Object

org.apache.harmony.security.utils.AlgNameMapper

public class AlgNameMapper
extends Object

Provides Algorithm Name to OID and OID to Algorithm Name mappings. Some known mappings are hardcoded. Tries to obtain additional mappings from installed providers during initialization.

Method Detail

addMapping

public static void addMapping(String oid,
                              String name)

Adds a mapping to the internal table. Will overwrite any entry already present. Visible for testing.

removeMapping

public static void removeMapping(String oid,
                                 String name)

Removes a mapping from the internal table. Visible for testing.

map2OID

public static String map2OID(String algName)

Returns OID for algName

Parameters:

algName - algorithm name to be mapped

Returns:

OID as String

map2AlgName

public static String map2AlgName(String oid)

Returns algName for OID

Parameters:

oid - OID to be mapped

Returns:

algorithm name or null if not found.

getStandardName

public static String getStandardName(String algName)

Returns Algorithm name for given algorithm alias

Parameters:

algName - - alias

Returns:

algorithm name

isOID

public static boolean isOID(String alias)

Checks if parameter represents OID

Parameters:

alias - alias to be checked

Returns:

'true' if parameter represents OID

normalize

public static String normalize(String oid)

Removes leading "OID." from oid String passed

Parameters:

oid - string that may contain leading "OID."

Returns:

string passed without leading "OID."

setSource

public static void setSource(AlgNameMapperSource source)
