I understand how to index the tables, what I don’t understand is how to determine the probability of success when using indexes.
For instance, the Hak5 NTLM tables (http://www.hak5.org/wiki/Community_Rainbow_Tables/Assignment_List) have 25 tables, with 22 chains per table. When using the criteria provided (ntlm mixalpha-numeric-all-space 1 7 0 10000 40000000 0), WinRTGen benchmarks a ~11% probability success rate, yet Hak5 claims ~95% success probability. How is that probability determined?
I’m still not understanding how to effectively use the table indexing feature. I would like to generate NTLM hashes for 1 to 10 characters, mixedalpha-numeric-symbol14, which will take quite some time on a single machine. However, I have 4 2.0GHz machines that I can split up this processing on… how do determine the probability success rate when more than an index of zero is used? Could someone provide example rtgen commands to run on each of the four machines I have available?
