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

Creates a Signature object instance of the selected algorithm.

Parameters:

algorithm - the desired Signature algorithm. Valid codes listed in ALG_ .. constants above e.g. ALG_DES_MAC4_NOPAD

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

Returns:

the Signature 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.
