Write a program that performs

Write a program that performs the brute-force attack to break the password. The following

table shows encrypted passwords using the crypt() function. Your mission is to break the

password ***** your CWID in the table. For example, the last digit of your CWID

is 1, then you should identify the password ***** indBOW06MoVz6.

Last digit of CWID Encrypted password

1 – indBOW06MoVz6

2 – in79RsnfG/VWo

3 – inbqJM0dLgWvo

4 – incT1ji3YqQ/Y

5 – in7haMV00ylgk

6 – in1U0tb9WpIcI

7 – inPlXS.yNKivQ

8 – inqidvfWapJp2

9 – injY7hdQJTeu2

0 – inQW.HgtuEe.M

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:

Input parameters:

• Password (plaintext): string

• Salt: string


• Encrypted password: stringThe password ***** 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. Report the original plaintext

password ***** breaking the encrypted password (one based on your CWID). Also report

how many words you tested to find the original password.
