![]() More information about password cracking can be found here. ![]() Another reason why this approach is so very effective is that Windows uses password hash functions that are very fast to compute, especially in an attack (for each given candidate password). This approach works because users generally select passwords that are easy to remember, and as a side-effect these passwords are typically easy to crack. It follows the same procedure used by authentication: it generates different candidate passwords (keys), hashes them and compares the computed hashes with the stored hashes. ![]() Hash Suite, like all other password hash crackers, does not try to "invert" the hash to obtain the password (which might be impossible). To authenticate a user, the password presented by the user is hashed and compared with the stored hash. This hash function is one-way in the sense that it is infeasible to infer a password back from its hash, except via the trial and error approach described below. ![]() To reduce this danger, Windows applies a cryptographic hash function, which transforms each password into a hash, and stores this hash. Storing user passwords in plain text naturally results in an instant compromise of all passwords if the password file is compromised. This tutorial was written using Hash Suite 3.4 Pro and assumes basic knowledge of password hashing and password hash cracking. ![]()
