WebJun 25, 2010 · Just replace the assignment to key in the code above with: import hashlib password = 'kitty' key = hashlib.sha256 (password).digest () Keep in mind that this 32-byte key only has as much entropy as your original password. So be wary of brute-force password guessing, and pick a relatively strong password ( kitty probably won't do). Python includes support for both in its standard library: import hashlib hashlib.sha1("this is my awesome password").digest() # => a 20 byte string hashlib.sha256("another awesome password").digest() # => a 32 byte string
