Project #1

Create a program that will create a SHA256 secure hash of a file

To create a hash of text ...

import hashlib
m = hashlib.sha256()
m.update(b'Now is the winter of our discontent')
m.update(b'Made glorious summer by this son of York;')
m.update(b'And all the clouds that lour\'d upon our house')
m.update(b'In the deep bosom of the ocean buried.')
print('m.digest    is {}'.format(type(m.digest())))
print('m.hexdigest is {}'.format(type(m.hexdigest())))
##print(m.digest())
print(m.hexdigest())
print(m.digest_size)
print(m.block_size)

1. In the example code, change one character. What happens?
2. What hash algorithms are supported by hashlib?
3. Create a GUI version of the program. (use FileDialog widget)
