In this project, you are given a password file "passwords.txt", the file lists a number of passwords, however, in SHA-1 hashed version. Each line of the file has the following format: [Uer ID] [SPACE] [SHA-1 Hash of The User's Password]. For example: the first two lines of the file is 1 7c4a8d09ca3762af61e59520943dc26494f8941b 2 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 First, please verify User 1's password is "123456" using this website: http://www.sha1-online.com/ Your goal in this project is to crack the passwords in the file as many as possible. You are givein the following knowledge about the (bad!) practice of people setting up their passwords: Some people tend to use only a few digits as passwords Examples: 0000, 123456, 012, 20170101, . o Some people tend to use English words or phrases or short sentences as passwords (not safel) o Examples: university, good, password, reallygood, greatday Some people combine English words and numbers, but they generally place few numbers after the English words. . Examples: university17, password123, great007 o In this project, you can safely assume that all English words are lower-case, and all of them are chosen from a given dictionary file "dictionary.tx?. You can use any computer language (Java, C/C++, Python, R, Matlab, ...) and leverage any existing open-source software, tools, or commands (e.g., sha1sum in Linux) to design the cracking system. You must detail your strategy and give the results in the report. Generally, you may need to rurn your code on a (faster?) computer for a (large?) number of days. It really depends on your cracking strategy!!! In this project, you are given a password file "passwords.txt", the file lists a number of passwords, however, in SHA-1 hashed version.
