Word list generator to crack security tokens.

Example use case

1. You are testing reset password function
   
2. Reset password token was sent to your email box (e.g. 582431d4c7b57cb4a3570041ffeb7e10)
   
3. You suppose, it is a md5 hash of the data you provided during registration process
   
4. You remember that on registration you entered the following data:
   
   • First name: Foo
   • Last name: Bar
   • Email: [email protected]
   • Birth date: 1985-05-23
   • Phone: 202-555-0185
   • Address: 3634 Forest Drive
5. In addition, you have an access to the following extra data:
   
   • Application user ID: 74824
   • Date of the reset password HTTP request ("Date" response header): Tue, 10 Mar 2020 17:12:59 GMT
6. You use Token Reverser to generate word list from the known data:
   

   ./token-reverser.py --date "Tue, 10 Mar 2020 17:12:59 GMT" Foo Bar [email protected] 1985-05-23 202-555-0185 "3634 Forest Drive" 74824 > words

7. You use hashcat to crack reset password token:
   

   hashcat64.exe -m 0 582431d4c7b57cb4a3570041ffeb7e10 words
   hashcat (v5.1.0) starting...
   [...]
   
   582431d4c7b57cb4a3570041ffeb7e10:[email protected]!1583860379
   
   Session..........: hashcat
   Status...........: Cracked
   Hash.Type........: MD5
   Hash.Target......: 582431d4c7b57cb4a3570041ffeb7e10
   [...]

8. Now you know that reset password tokens are generated as follow:
   

   md5(user ID!first name!last name!email!current timestamp)

Usage

usage: token-reverser.py [-h] [-d DATE] [-o TIMESTAMP_OFFSET] [-s SEPARATORS]
                         data [data ...]
