public final class IdeaMac
extends SymmetricCipherMac

A software based implementation of the DAC message authentication code algorithm that uses IDEA as the underlying symmetric cipher.

By default, this algorithm produces a 64 bit MAC, however, the MAC size can be configured via algorithm parameters; the allowed MAC sizes are 16 bits to 64 bits, in 8 bit increments. The following algorithm parameter specifications are supported:

• MacParameterSpec

An instance of this algorithm can be obtained using the Java Cryptography Architecture (JCA), by requesting an 'IDEAMac' MAC from the Entrust cryptographic service provider. This can be done using the following call:

Mac.getInstance("IDEAMac", "Entrust");

Constructor Detail

IdeaMac

public IdeaMac()

The constructor; creates a new instance of the IDEAMac MAC algorithm.

Applications should never use this constructor, instead the MAC algorithm should be requested from the appropriate JCA/JCE cryptographic service provider as follows: Mac.getInstance("IDEAMac", "Entrust").

FIPS 140-2:

FIPS Service: Modify Object

This API is part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; use of this API causes the caller to assume the FIPS 140-2 user role and accesses the following FIPS 140-2 logical interfaces:

• control input interface (API call)
• status output interface (exceptions)
