MD5 hashlib in Python is a module that allows you to encode strings of data into a hash value.
This is crucial in areas like cryptography and password protection, where you need to ensure your data’s integrity and security.
This tutorial guide will walk you through the installation process of the MD5 hashlib module in Python.
Step 1: Verify Python Installation
Before installing the MD5 hashlib module, ensure that Python is already installed in your system. You can do this by running the following command in your system’s terminal:
|
1 |
python --version |
If Python is installed, this command will return the Python version currently running on your system.
Step 2: Installation of MD5 Hashlib
The good news is, that the hashlib module (which includes MD5) comes pre-installed with Python 2.5 and above. You do not have to install it manually. You can directly import it into your script using the import function.
|
1 |
import hashlib |
Step 3: Testing MD5 Hashlib Functionality
After importing hashlib, you can now test the MD5 function. Here’s a simple Python script that encodes a string into an MD5 hash.
|
1 2 3 4 5 6 7 8 9 |
import hashlib md5_hash = hashlib.md5() # Sample text to hash text_to_hash = "hello world" # This text is hashed and then we print the hexadecimal equivalent. md5_hash.update(text_to_hash.encode()) print(md5_hash.hexdigest()) |
Running this script will give you the MD5 hashed value of the string “hello world”.
The full Python code:
|
1 2 3 4 5 6 |
import hashlib md5_hash = hashlib.md5() text_to_hash = "hello world" md5_hash.update(text_to_hash.encode()) print(md5_hash.hexdigest()) |
Output:

Conclusion:
Now you know how to use the MD5 hashlib in Python to encode data. It’s a simple but powerful functionality that plays a big role in data security and integrity—for example, storing passwords securely or verifying the integrity of files or data.
Furthermore, Python’s hashlib module provides functions for other common cryptographic hashing algorithms like SHA1, SHA224, SHA256, SHA384, and SHA512, amongst others.
