How to Fix the “No Module Named Crypto” Error in Python
Have you hit a roadblock in your Python coding journey when trying to work with cryptography, only to be met with the dreaded “No module named Crypto” error? Don’t despair, you’re not alone!
To understand why this error pops up, you need to know that the Python standard library doesn’t include a dedicated cryptography module. So, when you try to use a popular library like Pycrypto for encryption or decryption tasks, Python can’t find it.
But here’s the catch: Pycrypto is no longer the recommended choice due to security issues. So, what’s the solution? Enter Pycryptodome, a more secure and updated version of Pycrypto!
Steps to Fix the Error:
Install Pycryptodome: To get Pycryptodome on board, simply run this command in your command prompt:
pip3 install pycryptodome.Uninstall Pycrypto: Before you install Pycryptodome, make sure you don’t have Pycrypto installed. These two modules don’t play well together, so it’s best to avoid conflicts.
Update or Reinstall Pycryptodome: If you still encounter the error after installing Pycryptodome, try updating it with
pip3 install --upgrade pycryptoor reinstalling it withpip3 install --reinstall pycryptodome.Explore Alternative Libraries: In case Pycryptodome doesn’t solve your problem, there are other cryptography libraries available. Check out CryptoPlus, bcrypt, hashlib, or fernet.
Pros of Using Pycryptodome:
- Easy to use and beginner-friendly.
- Wide range of cryptographic algorithms.
- Regular updates and security patches.
Cons of Using Pycryptodome:
- Can be complex for advanced cryptography tasks.
- May not be suitable for all platforms.

FAQ
Q1: How to resolve the “ImportError: No module named ‘Crypto’” error in Python?
A1: This error occurs when the Pycryptodome library is not installed or imported correctly. To resolve it:
- Install Pycryptodome using pip:
pip3 install pycryptodome - Ensure that Pycrypto is not installed, as it installs under the same folder as Pycryptodome.
- Update Pycrypto, install Pycryptodome as a package in your IDE, or reinstall the package if the error persists.
Q2: Why is it recommended to use Pycryptodome instead of Pycrypto?
A2: Pycrypto is no longer safe to use due to security vulnerabilities. Pycryptodome is an actively maintained and secure fork of Pycrypto, and is the recommended alternative.
Q3: What should I do if I have both Pycrypto and Pycryptodome installed?
A3: Uninstall both packages and then install only Pycryptodome. Both packages install under the same folder, so having both installed can cause conflicts.
Q4: Can I use the “crypto” module instead of Pycryptodome?
A4: There is another module called “crypto” that may conflict with Pycryptodome. If you encounter issues, try renaming or removing the “crypto” module.
Q5: What are some alternative cryptography packages to Pycryptodome in Python?
A5: Other popular cryptography packages in Python include:
- Cryptographic Authority (cryptography): A high-level and easy-to-use cryptography library.
- hashlib: A standard Python library for hashing algorithms.
- Symmetric Cryptography (symmetric-cryptography): A library for symmetric encryption and decryption.
