                                             short keyLength,
                                             boolean keyEncryption)
                                      throws javacard.security.CryptoException

Creates uninitialized cryptographic keys for signature and cipher algorithms. Only instances created by this method may be the key objects used to initialize instances of Signature, Cipher and KeyPair. Note that the object returned must be cast to their appropriate key type interface.

Parameters:

keyType - the type of key to be generated. Valid codes listed in TYPE.. constants. See KeyBuilder.TYPE_DES_TRANSIENT_RESET.

keyLength - the key size in bits. The valid key bit lengths are key type dependent. Some common key lengths are listed above above in the LENGTH_.. constants. See KeyBuilder.LENGTH_DES.

keyEncryption - if true this boolean requests a key implementation which implements the javacardx.crypto.KeyEncryption interface. The key implementation returned may implement the javacardx.crypto.KeyEncryption interface even when this parameter is false.

Returns:

the key object instance of the requested key type, length and encrypted access

Throws:

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

• CryptoException.NO_SUCH_ALGORITHM if the requested algorithm associated with the specified type, size of key and key encryption interface is not supported.
