I am giving John the Ripper a file that may contain duplicate hashes, and get output like this:

2g 0:00:00:01  1.600g/s 3.200p/s 3.200c/s 70227C/s 123456789..abc123

Which represents the total number of unique passwords cracked over time. Is there a way to get total number of passwords (which contains duplicate password counts as well) cracked over time from John's output?

    You say file that may contain duplicate hashes. Do you really mean duplicate hashes - that is, same password and same hash? Or do you mean duplicate passwords with different hashes?

  • I mean same password with the same hash

  • Why don't you strip those out before running the tool? (Duplicate hashes likely means a weak password storage mechanism as salts should make hashes unique.)

    Because multiple people can have the same password. Frequency analysis of a given password corpus has significant research value.
