How to do it...

In the following steps, we will see how to obtain the hash of a file:

  1. Begin by importing the libraries and selecting the desired file you wish to hash:
import sysimport hashlibfilename = "python-3.7.2-amd64.exe"
  1. Instantiate the MD5 and SHA256 objects, and specify the size of the chunks we will be reading:
BUF_SIZE = 65536md5 = hashlib.md5()sha256 = hashlib.sha256()
  1. We then read in the file in chunks of 64 KB and incrementally construct our hashes:
with open(filename, "rb") as f:    while True:        data = f.read(BUF_SIZE)        if not data:            break        md5.update(data)        sha256.update(data)
  1. Finally, print out the resulting hashes:
print("MD5: {0}".format(md5.hexdigest()))print("SHA256: {0}".format(sha256.hexdigest()))
