The generated secure key is saved in a file with a size of 64 or 128 bytes.
The file contains an AES key with a length of 128, 192, or 256 bits. The key is
enciphered with the master key of the CCA or EP11 cryptographic adapter.
Secure keys that are used for the XTS cipher mode can be 128 or 256 bits
in size.
The generated secure key is saved in a file, and contains an AES secure key with
a length of 128, 192, or 256 bits, or two concatenated AES secure keys with a
length of 128, or 256 bits each, for keys that are used for the XTS cipher mode.
Note that the file size is not related to the key bit size, but is specific for
the secure key type. The key is enciphered with the master key of the CCA or
EP11 cryptographic adapter.
