I was reading that the designers of UNIX password algorithm used a 12 bit salt to modify the E-table of the unix hashing function (the DES). Supposing i have a system with 2^(24) users?
Is that ever possible to user dictionary attack? and if so how long would it take? years??
I am really new on computer security
Edit: I am not sure what unit time i guess i have to assuming bytes per minute depending on my code?
The reason I am asking is for a project where one of the questions states: "Consider a system with 2^24 users. Assume that each user is assigned a salt from a uniform random distribution and that anyone can read the password hashes and salt for users." What is expected time to find all users' passwords using dictionary attack?"
