There are 26*26 combinations of a two lowercase Latin alphabet letters, but 52*52 (4 times more) lower/upper case variants.Īttack complexity limit is 2^128 or 128-bit (2 raised to the power of 128). Two dictionaries with X and Y number of items respectively, can be combined into X*Y passwords candidates. Five-digit pin is 10 times more complex and requires 10 times more search time. The number of combinations equals to the multiplication of the number of items in each part.

Password candidates are generated as a composition of the parts (chars, words) and all possible combinations have to be processed. It is easy to see from examples that additional details (known or assumed) can used to shorten search time significantly.īasic combinatorics knowledge is handy for a search complexity assessment. Dictionary attack with capitalization and replacement option 'Aa->4' is a way faster alternative in this case. Mixed attack: 1 char 'A.Z' + 1 char '0.9' + 6 char 'a.z' is a lot faster. Example: password "P4ssword" can be discovered in a very slow manner with 8 char long brute-force search. There are multiple ways to search for the same password, time requirements are different as well. Password search is a guessing game - your password can be as simple as "1234" for example, but alphabetic-only search is not going to be successful in any timeframe when digits-based search expected to be quite fast. It is easy to see that password search is the only real option in such cases and our goal is to provide you with highly optimized tools with very flexible search patterns setup. Passwords are usually salted (random values are added) in order to block any preimage attacks or generation of rainbow tables. Hashing algorithms are commonly applied multiple times making known cryptanalysis research methods inapplicable.
