Today we learn about dictionary attack.

Dictionary attack

hashcat -a (attack mode code) -m(code of hash type) (hashing text or file) (wordlist file)

To see the code of the hash type:

hashcat — help

After typing, see the hash mode section

example attack

hashcat -a 0 -m 0 620a71f90d5dbf8c9a80939d2cbc1eba /root/Desktop/password.txt

password.txt content:
