[Bug 1981796] [NEW] Python3-crypto fails

[Vince Ricosti]

Public bug reported:

When I try to use crypto from python3(Python 3.10.4) I get errors:

vricosti at vricosti-Z490-VISION-D:~$ python3 --version
Python 3.10.4
vricosti at vricosti-Z490-VISION-D:~$ pip3 freeze | grep crypto
crypto==1.4.1
cryptography==3.4.8
pycrypto==2.6.1


First error:
--------------
import sys
import os
from Crypto.Cipher import AES
from Crypto import Random

iv = Random.new().read( AES.block_size )

I get the exception: module 'time' has no attribute 'clock'
------------

Second error:
--------------
import sys
import os
from Crypto.Cipher import AES
from Crypto import Random

def decrypt(key, ciphered_filepath):
    with open(ciphered_filepath,"rb") as f:
        content = f.read()
        if len(content) > 16:
            iv = content[0:16]
            cyphertext = content[16:]
            cipher = AES.new(key, AES.MODE_CFB, iv)
            plaintext = cipher.decrypt(cyphertext)

decrypt('4STDs9cmUlkiujXuLkdTouoqOIfER4TE',
'/home/vricosti/testfile.jpg')

I get the exception: PY_SSIZE_T_CLEAN macro must be defined for '#'
formats
