Detailed Description

Struct tracks a key and its properties.

Each open instance of the crypto device has a des_key_structure associated with it not only does it remember the key used for that session but other details that need tracking over a DES session

Data Fields
unsigned char	Key0 [8]
unsigned char	Key1 [8]
unsigned char	Key2 [8]
int	encrypt
int	master
int	raw
axis_des_hardware_key *	hardware_key

Field Documentation

int axis_des_key::encrypt

Is this an encrypt or decrypt op

struct axis_des_hardware_key* axis_des_key::hardware_key

If a hardware key has been allocated this is it

unsigned char axis_des_key::Key0[8]

3DES so 3 64 bit keys key 1

unsigned char axis_des_key::Key1[8]

3DES so 3 64 bit keys key 2

unsigned char axis_des_key::Key2[8]

3DES so 3 64 bit keys key 3

int axis_des_key::master

Flag use master key

int axis_des_key::raw

Raw keys are used straigh otherwise key is decrypted prior to use
