sha-1-password-cracker

The function that takes in a SHA-1 hash of a password and returns the password if it is one of the top 10,000 passwords used. If the SHA-1 hash is NOT of a password in the database, return "PASSWORD NOT IN DATABASE".

The function should hash each password from top-10000-passwords.txt and compare it to the hash passed into the function.

The function should take an optional second argument named use_salts. If set to true, each salt string from the file known-salts.txt should be appended AND prepended to each password from top-10000-passwords.txt before hashing and before comparing it to the hash passed into the function.

Here are some hashed passwords to test the function with:

  • b305921a3723cd5d70a375cd21a61e60aabb84ec should return "sammy123"
  • c7ab388a5ebefbf4d550652f1eb4d833e5316e3e should return "abacab"
  • 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 should return "password"

Here are some hashed passwords to test the function with when use_salts is set to True:

  • 53d8b3dc9d39f0184144674e310185e41a87ffd5 should return "superman"
  • da5a4e8cf89539e66097acd2f8af128acae2f8ae should return "q1w2e3r4t5"
  • ea3f62d498e3b98557f9f9cd0d905028b3b019e1 should return "bubbles1"
