Python Program to Find the Hash of the File – 2025

Hey guys, in this blog we will see a Python Program to Find the Hash of the File.

Code

# Python program to find the SHA-1 message digest of a file

# importing the hashlib module
import hashlib

def hash_file(filename):
    """"This function returns the SHA-1 hash
    of the file passed into it"""

    # make a hash object
    h = hashlib.sha1()

    # open file for reading in binary mode
    with open(filename,'rb') as file:

        # loop till the end of the file
        chunk = 0
        while chunk != b'':
           # read only 1024 bytes at a time
            chunk = file.read(1024)
            h.update(chunk)

    # return the hex representation of digest
    return h.hexdigest()

message = hash_file("img1.jpg")
print(message)

Output

The following Hash is for an Image file.
