Crypt() is a function to check UNIX/LINUX passwords, and the encrypted passwords above are encoded by the standard crypt() function. Hence, you should use the crypt() function to break the password. The crypt() function takes two input parameters and returns the encrypted password, as follows:
1
The password length is six and the salt is set to ‘infosec’ (without using the quotation mark). For the brute-force attack, you should try 6-character lower case letters of alphabet from ‘aaaaaa’, ‘aaaaab’, ‘aaaaac’, …, to ‘zzzzzz’, with the salt. Also report how many words you tested to find the original password. IN PYTHON KEEP IT SIMPLE
