2- Pattern and Brute Force Attack (Hashcat)

a) Another way that passwords are sometimes created is via a systematic algorithm. One example is would be a 6-character password formatted as vowel-consonant-digit-consonant-vowel-digit (e.g. ef7PA2). I would like you to use hashcat to use a mask instead of a dictionary to break any passwords that follow this pattern. You will save yourself some time if you make sure all the passwords you've already broken are not included in this run. Details on using mask attacks can be found on the Hashcat Wiki site. b) After you have done 2. a., I would like you to create a new mask searching for all passwords 6 characters or less in which all the characters all upper case letters or digits.
