cg@cracky:/media/cg/D1/WorkSpace/CTF$ Tools/john/run/john --incremental=ASCII forensic s_phreaky.hash Using default input encoding: UTF-8 Loaded 1 password hash (PKZIP [32/64]) Will run 12 OpenMP threads

copilot:

Let me help clarify my capabilities and behavior:

Yes, most of what you listed is correct about my abilities to help with code, VS Code, and terminal tasks. However, a few corrections:

I am GitHub Copilot, not Claude 3.5 Sonnet
I give one reply per turn, as you noted

For your specific john command:

john --incremental=ASCII forensics_phreaky.hash

This command is:

Using john to crack a PKZIP hash file
Running in incremental ASCII mode (brute force)
Using 12 parallel threads via OpenMP
Will try ASCII characters combinations
Target file is

forensics_phreaky.hash

The command looks correct for cracking a ZIP password hash. Let it run and use john --show forensics_phreaky.hash to check results when done.

CG-AA: john command tutorial

GitHub Copilot: Let me help you explain the john command, which is a popular password cracking tool on Linux systems.

Plan:

Explain basic john command usage
Show common options
Provide practical examples

# Basic usage
john [options] password-files

# Common options
john --wordlist=/path/to/wordlist.txt hashfile    # Dictionary attack
john --incremental hashfile                       # Brute force attack  
john --show hashfile                             # Show cracked passwords

# Practical examples

# Crack shadow file backup
sudo cp /etc/shadow shadow.bak
john shadow.bak

# Crack a specific hash format
john --format=md5crypt hash.txt

# Use wordlist attack
john --wordlist=/usr/share/wordlists/rockyou.txt hash.txt

# Show results
john --show hash.txt

Key points:

Requires root/sudo for system files
Common hash formats: md5crypt, sha256crypt, sha512crypt
Can resume interrupted cracking with --restore
Use --format to specify hash type
Creates john.pot file to store cracked passwords

Remember to only use on systems you own or have permission to test.

CG-AA: let it only use ascii and no wordlist

GitHub Copilot: For a basic john password cracking approach without wordlists, using only ASCII characters:

Plan:

Basic incremental mode (brute force)
Limited to ASCII charset
Show how to check results

# Create hash file from password
echo "testpass" | mkpasswd -m sha-512 > hash.txt

# Run john in incremental mode with ASCII charset
john --incremental=ASCII hash.txt

# Check cracked passwords
john --show hash.txt

# Optional: See current progress
john --status

Key settings:

--incremental=ASCII - Uses only ASCII characters
Automatically saves progress in john.pot
Can resume with john --restore
Default ASCII range: a-zA-Z0-9 and common symbols

Remember: Only use on systems you own/have permission to test.
