*this RAR file is intended to be cracked, full permission granted I am tasked to crack a password [from a .RAR (not RAR5, this is an older rar format) RAR 3.0 Protection (2^128) that is 16 characters minimum, with it potentially being as long as 23 characters. Now I know what you are thinking. "DICTIONARY ATTACK!!" - Not applicable in the case, I was informed a dictionary attack will not help, even using some of the terabyte-sized lists. "TIMETIMETIME! You will be dead before you get the password!" - If the above was all I had to work with, then I agree! Here is the catch: Only the following characters are possibly used in the password Code: acdehimnprsty ACDEHIMNPRSTY 3$* ^ caps and lowercase are the same letters, only numbers and symbols are '3' '$' and '*' Suddenly the challenge is more possible, but its not enough. So, we are given the first 8 characters of the password, however the second letter is an 's' and may be replaced with 's' 'S' or '$'. - Which makes this a bit more challenging. I have already looked into some software solutions like "RAR Password Unlocker" (this program supports Brute-force with Mask Attack, which is great) however, it is limited to a maximum of 16 characters. Where can I start with this, and what software [paid is fine] could possibly crack the above within the requirements? I found the freeware RAR Password Cracker, and it seems like a usable solution. Giving it a try. RAR 3.0 protection is the biggest issue, since it limits machines to less than 100 passwords per second.
