The final parameter in the hash function is the length of the derived key.We use the 'b' character before the string to convert it to bytes. The next parameter is the salt we want.We have to encode this to 'utf-8' before passing it into the hash function. The second parameter is the string we want to hash.The pbkdf2_hmac() function's first parameter is the way we will hash the password.Note that we are resetting the pwd variable so that the raw string password is deallocated from memory, and is therefore unhackable. This creates a SHA256 hash of the password and adds a "salt" at the end. Under the last line you wrote, add this: pwd = hashlib. But as you'll find out in a second, we'll need to do a lot more than that if we want our password generator to be secure. In Python, input() prompts the user for input and stops until they input something.Īfter getting the user's choice, ask them for their password: pwd = input ( "Password: " )įor now, we're going to store the password in plaintext in a temporary variable. Under the import statement, add: choice = input ( 'Are you\n(1) Signing Up\n(2) Signing In?: ' ) This will allow us to hash and salt our passwords using a popular hashing algorithm called SHA256. Start by importing the hashlib module from the built-in Python library. Now we're ready to start coding! Writing code This is where you'll be writing all of the code for this project. Once your repl spins up, you should be dumped into an empty file called main.py. Get started by visiting /languages/python3. We're going to use, a free, online code editor, to write the code for this project. Have you ever wanted to learn how exactly passwords are generated? In this workshop, we're going to dive deep into cybersecurity, and along the way we'll make a secure password generator with Python.
