CRACKING MD5 HASHES

root@oco:~$ hashid {pwHash}
root@oco:~$ echo -n '{passwordHash}' > passwordHash

root@oco:~$ hashcat -a 0 -m 0 passwordHash /usr/share/wordlists/rockyou.txt

 * the "-a 0" specifies the attack mode. 0 means straight mode, which is the simplest 
   and most common mode where hashcat attempts to crack the hash by directly using 
   wordlist entries.

 * the "-m 0" specifies the hash type. 0 means MD5 hashes. So, hashcat will treat the 
   hashes in the hash file as MD5.
