"WebSep 10, 2024 · Hash cracking : Hash cracking entails taking a large wordlist or dictionary and hashing each word. Then, you check the hash of each word in the dictionary against the hash you are trying to crack. Once you have found a match, you have found your word! This is why it is not recommended to use common words as your password. " - Cryptographic hash definition
