Convert file to hash format


# For example
ssh2john id_rsa_encrypted > hash
Sample Output:
TO-DO


keepass2john test.kdbx > hash
Sample Output:
TO-DO


zip2john test.zip > hash
Sample Output:
TO-DO


# Get a full list of *2john
find / -name *2john 2>/dev/null
Sample Output:
TO-DO


# General use
john --wordlist=/usr/share/wordlists/rockyou.txt hash
Sample Output:
TO-DO


# Specify hash format
john --wordlist=/usr/share/wordlists/rockyou.txt hash --format=Raw-SHA512
Sample Output:
TO-DO


# Show cracked hash
john --show hash
Sample Output:
TO-DO


# Show cracked hash with specific format
john --show hash --format=Raw-SHA512
Sample Output:
TO-DO


# Auto detect hash format
hashcat hash
Sample Output:
TO-DO


# Specify hash format
hashcat -m <MODE> -a 0 hash /usr/share/wordlists/rockyou.txt --force
Sample Output:
TO-DO


# Auto skip username and colon
hashcat hash --user
Sample Output:
TO-DO

Create a wordlist


# For example, 'Test' with 4 digits and a symbol
hashcat --stdout -a 3 Test?d?d?d?d?s > passwords.txt
Sample Output:
$ hashcat --stdout -a 3 Test?d?d?d?d?s > passwords.txt
$ head passwords.txt
