I know that John the ripper incremental mode does a brute force like attack in all possible combinations given that you choose the charset and the length of the password. What order does JTR use when trying the passwords? It doesn’t seem to use alphabetical order?
Clang on OSX doesn’t support OpenMP by default, so I could not compile JtR with OpenMP support without another Clang installation.
However, after looking at the below option, I wonder what the difference is compared to OpenMP mode:
--fork=N fork N processes
If I invoke JtR using
--fork=2, then JtR will run with two processes, executed on different physical processor cores (same as OpenMP)?
For migration purposes i need to get the plaintext password for all our accounts.
Our system uses usernames in the format “firstname.lastname” and password is either “firstname + single_number + single_letter” or “lastname + single_number + single_letter”, like “firstname3p” or “lastname3p”
What is the correct way to use filters to extract firstname or lastname and try every combination of number + letter on them?
