Experiment-2.

Student Name: Akashdeep Singh UID: 24MCS10003


Branch: ME-CSE Section/Group: 24MCS1/A
Semester: 2 Date of Performance: 20/03/2025
Subject: Information Security Subject Code: 24CSH-662

1. Aim: Calculate the message digest of a text using the MD5 algorithm.

2. Task to be done:
• Understand the concept of cryptographic hash functions and message digests.
• Learn about the MD5 algorithm and its characteristics.
• Implement MD5 hashing for a given text input.
• Display and verify the generated hash value.

3. Software Required: Online Python Compiler

4. Description:

A message digest is a fixed-size output generated from an arbitrary length input, ensuring data integrity
during transmission or storage.
MD5 is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically
represented as a 32-character hexadecimal number. It is fast and commonly used for file verification and
checksums, though it is not recommended for security-critical applications due to vulnerabilities.

5. Algorithm:

• Take a text input from the user or define a fixed text.


• Encode the text into bytes, since the MD5 algorithm works on byte sequences.
• Apply the MD5 hashing algorithm to the encoded text.
• Generate the hexadecimal representation of the resulting hash.
• Display the original text and its corresponding MD5 message digest.

6. Code And Output:

import hashlib

# Input text

Akashdeep Singh 24MCS10003


text = "Hello, welcome to MD5 hashing!"

# Encoding the text to bytes


encoded_text = text.encode()

# Creating MD5 hash object


md5_hash = hashlib.md5(encoded_text)

# Getting the hexadecimal digest


digest = md5_hash.hexdigest()

# Displaying the message digest


print("Original Text:", text)
print("MD5 Message Digest:", digest)

7. Learning Outcomes:

• Understood the role and functioning of cryptographic hash functions.


• Learned the features and limitations of the MD5 algorithm.
• Gained practical experience in implementing MD5 hashing using Python.
• Developed skills to generate and interpret message digests for data verification.
• Recognized the importance of data integrity and the effect of input changes on hash outputs.
