pycryptodome version

It seems V2 decrypt fails for the latest version of pycryptodome.
I have run the script installing the version 3.8.2 (pip3 install pycryptodome==3.8.2)

PD: This script saves my day!

Make Error : **AttributeError: function 'SHA512_init' not found**

Everyone , Im make securecrt_cipher.py after appear this Error information : AttributeError: function 'SHA512_init' not found , Please help me . Thank's.

1. In below is command information :

Notie : my any version information
Windows 11 x86-64bit
Python 3.11.6
pip 23.2.1

Package version :
PS C:\Users\Horry> pip list
Package Version
------------ -------
pip 23.2.1
PyAudio 0.2.11
pycrypto 2.6.1
pycryptodome 3.19.0
setuptools 65.5.0
wheel 0.41.2

ModuleNotFoundError: No module named 'Crypto'

It looks like environments above python3.8 are prone to this reporting error, even if you install the “requirements”.
so follow the steps:
pip3 uninstall crypto
pip3 uninstall pycrypto
pip3 install pycrypto

File name too long

Getting "file name too long" with the following syntax

sudo ./securecrt_cipher.py dec -2 --prefix 02 9c9b072741bff2069616b3bd47a...8b529278580b69aa8aab0e4b12c21bbfdf58f6089a4a6267782f7658e23e8ab83d9b1d84fa470ead0c1b153418e3c475a731f4e4 encryptionkey

pycryptodome: 3.19.0
python: 3.9.2

Only thing I can think is that the encryption key is too long @ 36char?

ScureCRT 9.4

ScureCRT 9.4 with a new type encryption，"Password V2"=03:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

NameError: name 'xrange' is not defined

Hi man , I followed the steps you in bellow described,
https://github.com/HyperSine/how-does-SecureCRT-encrypt-password/blob/master/README.md
and I got this error :

E:\Database\python>python securecrt_cipher_1.py dec -2 --prefix 03 70e0ef15dd8**********************ecb

^^^^^^

NameError: name 'xrange' is not defined. Did you mean: 'range'?

Please's help me deal with this problem . Thinks man .

Notie .
and Im python version is : 3.11.6
pip version is : 23.2.1

raise ValueError('Bad ciphertext: incorrect padding.')

Question about the Config Password

This script works without any issues when the config password is known, but what about if that's NOT known? When you attempt to decerypt a stored session's password without supplying the config password (using -p ) in the string, you get back an error message about invalid cypher text length. For example, if you have the .ini files from a former employee's saved sessions but don't know the config password they used to get into SecureCRT, how do you decrypt the stored session's hash?
