A simple password cracker that uses the SHA-1 hashing algorithm to crack passwords. It uses a dictionary of common passwords to check if the password is in the dictionary. If the password is in the dictionary, it will display the password and the number of attempts it took to crack the password.

I learnt about the SHA-1 hashing algorithm and how it is used to hash passwords. I also learnt about the dictionary attack and how it is used to crack passwords. I learnt how to use the hashlib library in Python to hash passwords and how to use the itertools library to generate all possible combinations of a given length.
