== How to fix it in PyCrypto
|

==== Noncompliant code example
|
||
|
|
|
||
|
|
[source,python,diff-id=1,diff-type=noncompliant]
|
||
|
|
----
|
||
|
|
from Crypto.Cipher import DES
|
||
|
|
|
||
|
|
cipher = DES.new(key) # Noncompliant
|
||
|

|
==== Compliant solution
|
||
|
|
|
||
|
|
PyCrypto is deprecated, thus it is recommended to use another library like pyca.

cipher = Cipher(algorithms.AES(key), modes.CBC(iv), backend=default_backend())
