The Problem

You're mid-exam - OSCP, PNPT, CPTS, whatever - and you need to spray some passwords. Clock's ticking. Your options suck:

1. Grab a massive wordlist - Spray 50k passwords, lock accounts, waste time
2. Write regex on the spot - Spend 10 minutes fighting with sedawkgrep while your brain rots

Neither option is good when you're already stressed and every minute matters.

Why I Built This

Hit this exact problem several times, for example: on Nagoya from Proving Grounds. Needed seasonal passwords fast. Started with a quick bash one-liner that worked great for that box.

Then I kept running into the same situation on other machines. Kept rewriting similar regex patterns every time. So I rewrote it in Python. Now it's reusable, no regex required, generates what you need in seconds.

When you need Winter2024! or Spring2024! during an exam, you shouldn't waste mental energy on wordlist generation. Just run the tool and get back to actually breaking stuff.

Use Cases

Built with cert labs in mind (OSCP, PNPT, CPTS) but works anywhere you need clean spray lists:

• AD password spraying
• CTF boxes
• Any time you need realistic date-based passwords

Usage

# No arguments? See the help
python3 nagoyaspray.py

# Example output
Example: python3 nagoyaspray.py --seasons --months --start 2020 --end 2025 -s "!" -o passwords.txt

Basic Examples:

# Seasons + months with suffix (default: first letter capitalized)
python3 nagoyaspray.py --seasons --months --start 2020 --end 2025 -s "!" -o passwords.txt

# All word types with multiple suffixes
python3 nagoyaspray.py --all --start 2023 --end 2024 -s "!,123,@" -o passwords.txt

# Add prefix instead
python3 nagoyaspray.py --months --start 2024 --end 2024 -p "!" -o passwords.txt

# Generate only passwords between 8-12 characters
python3 nagoyaspray.py --seasons --start 2024 --end 2024 -s "!" --min 8 --max 12 -o passwords.txt

# All lowercase passwords (no capitalization)
python3 nagoyaspray.py --months --start 2024 --end 2024 -s "!" --cap lower -o passwords.txt

# Custom words
python3 nagoyaspray.py -w "Company,Admin" --start 2023 --end 2024 -s "!" -o passwords.txt

# Both prefix and suffix
python3 nagoyaspray.py --seasons --start 2024 --end 2024 -b "!" -o passwords.txt

Flags:

• --months - Include months
• --seasons - Include seasons
• --days - Include days of the week
• --common - Include common words
• --all - Include everything
• -w - Custom comma-separated words
• --start / --end - Year range
• -s - Suffix (add at end)
• -p - Prefix (add at start)
• -b - Both (add at start and end)
• --cap - Capitalization mode: first (default - first letter capitalized), lower (all lowercase), upper (all uppercase), last (last letter capitalized), all (all variations)
• --min - Minimum password length (default: 1)
• --max - Maximum password length (default: 100)
• -o - Output file (required)
• --print - Print to stdout instead

Note: By default, all passwords have their first letter capitalized (e.g., Winter2024!). Use --cap lower for all lowercase or --cap upper for all uppercase.
