Python is a universal language that you can use for various purposes. One such use is cryptography or the practice of secure communication in the presence of third parties.
While cryptography is possible in Python, specific modules are required in order to make it work. In some cases, these modules may not be installed by default on your system.
In case you encounter an ImportError: No module named Crypto. Cipher error, here are a few steps you can take to solve the issue. Keep reading to learn more!
When Did The ImportError: No module named Crypto. Cipher Error Occur?
Crypto. Cipher is a module that provides cryptographic primitives for Python programs. It contains implementations of several standard symmetric-key encryption algorithms and a few message authentication codes (MACs).
If you’re trying to import the AES function from this module, you may run into an ImportError: No module named Crypto.Cipher error.
This error can occur if the module isn’t installed on your system or installed in a different location than where your Python program is looking for it.
You can follow our instructions in the following sections to fix this error. Let’s scroll down now!
3 Wonderful Tricks To Solve The Problem
This section will provide three ways to solve the error mentioned above.
Pycrypto is a library that allows developers to create and manipulate cryptographic objects in Python. It can be installed using pip in a few easy steps.
Step 1: Open a command line and type the following command:
pip uninstall pycrypto
If you want to remove this module from your system, you can also do it through Python’s built-in uninstaller.
Step 2: Install the module again with this line:
This should automatically resolve the error. If not, try installing it again using a more recent version.
To remove PyCrypto and Crypto, you can use pip to uninstall them. However, this will only remove the Python package and not the external library or any of its dependencies. The following commands will be useful for you.
sudo pip uninstall pycrypto sudo pip uninstall pycrypto
The next step is to set up pycryto with this line:
sudo pip install pycrypto
You’ll be able to add the following content directly to your document now:
from Crypto.Cipher import AES
Pycryptodome is a more up-to-date library for cryptography than pycrypto. It offers more features and is less likely to have security vulnerabilities. If you need to use cryptography in your code, you can use pycryptodome instead of pycrypto.
Here is the command you can apply:
pip3 uninstall crypto pip3 uninstall pycrypto pip3 install pycryptodome
In conclusion, there are several ways to solve the ImportError: No module named Crypto.Cipher error.
If you are uncertain of which method to use or are experiencing problems with one of the methods, you can contact a support specialist. We hope you can fix your issue efficiently. Thanks for reading!
