Brute-force attacks can be made less effective by obfuscating the data to be encoded, something that makes it more difficult for an attacker to recognize when he/she has cracked the code. The key length used in the encryption determines the practical feasibility of performing a brute-force attack, with longer keys exponentially more difficult to crack than shorter ones. In the worst case, this would involve traversing the entire search space. It involves systematically checking all possible keys until the correct key is found. Such an attack might be utilized when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. “In cryptography, a brute-force attack, or exhaustive key search, is a strategy that can, in theory, be used against any encrypted data.
