                  YHSM_Cmd_AES_ECB_Compare

Have the YubiHSM AES ECB decrypt something using the key of a key handle, and then compare it with a plaintext we supply.

Requires you to know the plaintext to verify if the ciphertext matches it, providing added security in some applications.

Instance Methods

__init__(self, stick, key_handle, ciphertext, plaintext)
The base class for all YSM_ commands.

parse_result(self, data)
This function is intended to be overridden by sub-classes that implements commands that should not just return the data read from the YubiHSM.

Inherited from YHSM_Cmd_AES_ECB: __repr__

Inherited from cmd.YHSM_Cmd: execute

Class Variables

Inherited from YHSM_Cmd_AES_ECB: key_handle, status

Inherited from cmd.YHSM_Cmd: executed, response_status

Method Details

init(self, stick, key_handle, ciphertext, plaintext)
(Constructor)

The base class for all YSM_ commands.

Parameters:

stick - Reference to a YubiHSM
command - The YSM_xxx command defined in pyhsm.defines.
payload - a packed C struct, represented as a Python string

Overrides: cmd.YHSM_Cmd.__init__
