How to hash a string in Python

Question

I simply want to hash a string (a Password) in Python 3. How do I do that? What is a Simple Way of doing that? Could you please give a Coding example or Recommend me a Module that can use.

What do you mean by hashing? Like assigning a key to each value? Or like password encryption? — CoderTang, Dec 27 '21 at 17:17

You can hash values in Python 3 with Hashlib:

import hashlib
h = hashlib.new('sha256')#sha256 can be replaced with diffrent algorithms
h.update('Hello World'.encode()) #give a encoded string. Makes the String to the Hash 
print(h.hexdigest())#Prints the Hash

hashlib is part of core python - isnt it? (why pip install ?) – balderman Dec 27 '21 at 17:12

What diffrent Algorithms can i use? – copycode Dec 27 '21 at 17:17
@copycode You can see all Algorithms usable by printing out `hashlib.algorithms_available()` but I recommend sicking to sha256 because some algorithms are old/outdated. – urwolfiii Dec 27 '21 at 17:21

I don't think there can be an easier way than using the built-in keyword hash:

In [1]: hash("Hello, world!")
Out[1]: 7195831199436619873
