To write a program to implement the MD5 hashing technique.

STEP-1: Read the 128-bit plain text.

STEP-2: Divide into four blocks of 32-bits named as A, B, C and D.

STEP-3: Compute the functions f, g, h and i with operations such as, rotations, permutations, etc,.

STEP-4: The output of these functions are combined together as F and performed circular shifting and then given to key round.

STEP-5: Finally, right shift of ‘s’ times are performed and the results are combined together to produce the final output.

#Code to demonstrate the MD5

import hashlib

# function 
result = hashlib.md5(b'GeeksforGeeks')

# printing the equivalent byte value.
print("The byte equivalent of hash is : ", end ="")
print(result.digest())

Thus the implementation of MD5 hashing algorithm had been implemented successfully using C.
