public static final javacard.security.Checksum getInstance(byte algorithm,
                                                           boolean externalAccess)
                                                    throws javacard.security.CryptoException

Creates a Checksum object instance of the selected algorithm.

Parameters:

algorithm - the desired checksum algorithm.

externalAccess - true indicates that the instance will be shared among multiple applet instances and that the Checksum instance will also be accessed (via a Shareable. interface) when the owner of the Checksum instance is not the currently selected applet. If true the implementation must not allocate CLEAR_ON_DESELECT transient space for internal data.

Returns:

the Checksum object instance of the requested algorithm.

Throws:

javacard.security.CryptoException - with the following reason codes:

• CryptoException.NO_SUCH_ALGORITHM if the requested algorithm or shared access mode is not supported.
