Python Program to Find Hash of File: In this article, you’ll learn to find the hash of a file and display it.
Hash functions take an arbitrary amount of data and return a fixed-length bit string. They are widely used in cryptography for authentication purposes.
Python Program to Calculate a Hash of a File
# Python rogram to find the SHA-1 message digest of a file # import 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("track1.mp3") print(message)
