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. WebAn example This example uses the common unix utility "md5sum", which hashes the data on stdin to a 128 bit hash, displayed as 32 hex digits. Assume the password is "mysecretpass" and both the client and the server know this.The client connects to the server. The server makes up some random data, say "sldkfjdslfkjweifj ”.The server sends this data to client.
