Hash a large file in Python
import hashlib as hash
# Specify how many bytes of the file you want to open at a time
BLOCKSIZE = 65536
sha = hash.sha256()
with open('kali.iso', 'rb') as kali_file:
file_buffer = kali_file.read(BLOCKSIZE)
while len(file_buffer) > 0:
sha.update(file_buffer)
file_buffer = kali_file.read(BLOCKSIZE)
print sha.hexdigest()
