getInstance

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

Creates a Cipher object instance of the selected algorithm.

Parameters:

algorithm - the desired Cipher algorithm. Valid codes listed in ALG_ .. constants above, for example, Cipher.ALG_DES_CBC_NOPAD

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

Returns:

the Cipher object instance of the requested algorithm

Throws:

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

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