Can i crack more than 1 hash simultaneously like most other password cracker softwares do ?
yes and no. MDCrack will accept only one hash from the command line and all threads will work together, cooperatively, on this very same hash. However, you can launch as many MDCrack processes you wish and thus can simultaneously crack several hashes. Multi-processors system owners can additionnally reserve a processor for each process worker thread. This is however not exactly the same as taking multiple hashes from the same command line. Indeed, testing multiple hashes in the same threads allow for greater overall speed than testing them in separate processes. This feature will be added in a next release.
