Explanation

A brute force attack systematically tries every possible combination of characters from a defined character set (lowercase, uppercase, digits, symbols) until the correct password is found. It is exhaustive and guaranteed to eventually crack any password, but is extremely slow for long or complex passwords. In contrast, a dictionary attack uses a predefined wordlist, a rainbow table attack uses precomputed hash chains, and a rule-based attack applies transformation rules to words - none of these try every possible combination.
