keygen-dictionary 1.0.0

OSINT-based password dictionary generator for authorized security testing

keygen-dictionary

OSINT-based password dictionary generator for authorized security testing.

Takes personal data (name, date of birth, address, domain, etc.) and produces a targeted wordlist sorted by Shannon entropy — human-like combinations first.

Warning For authorized use only. Only use against systems you own or have explicit written permission to test. The author is not responsible for misuse.

Features

• Interactive mode with guided prompts (questionary)
• One-liner CLI mode via flags — scriptable, no prompts
• YAML config file support for repeatable target profiles
• --config-save to dump session inputs to YAML for reuse
• Entropy sort — low-entropy (human-like) candidates first
• Leet speak variants — default a→4 e→3 i→1 o→0 s→5, fully overridable via --leet or config
• Case variants — .title(), .upper(), .capitalize() generated per token
• Common suffixes seeded automatically (!, 123, 1234, #1, …)
• Min/max length filter to match real password policies
• Streamed output — RAM-safe even at combination level 3+
• --dry-run to preview token count before committing
• -q / --quiet for clean output when piping or scripting

Installation

From source (recommended):

git clone https://github.com/ivanhuay/keygen-dictionary.git
cd keygen-dictionary
python3 -m venv .venv && source .venv/bin/activate
pip install -e .

Requirements: Python 3.10+

Usage

Interactive mode

Run with no flags to enter guided prompts:

keygen-dictionary

keygen-dictionary v1.0.0 — leave any field empty to skip

Combination level: 2
Min password length (0 = no limit): 8
Max password length (0 = no limit): 16
Full name: John Doe
Domain URL: example.com
Birth/important date (dd-mm-yyyy): 01-01-1990
...

  Tokens collected : 169
  Est. candidates  : ~28,730
  Sample           : !, !!, #1, ...

Proceed with generation? (Y/n)

CLI mode

Pass any data flag to skip interactive prompts entirely:

keygen-dictionary \
  --name "John Doe" \
  --domain example.com \
  --date 01-01-1990 \
  --level 2 \
  --min-length 8 \
  --max-length 16 \
  --output wordlist.txt \
  --entropy-sort

Multiple values per field:

keygen-dictionary --name "John Doe" --name "Johnny" --additional "fido" --additional "chelsea"

Preview without generating:

keygen-dictionary --name "John Doe" --date 01-01-1990 --dry-run

Custom leet substitutions and quiet output for piping:

keygen-dictionary --name "John Doe" --leet "a:@,s:$" -q --output - | head -20

Config file mode

Create a YAML profile (see config.example.yaml):

name:
  - "John Doe"
domain:
  - "example.com"
date:
  - "01-01-1990"
additional:
  - "fido"
level: 2
min_length: 8
max_length: 20
leet_map:           # optional — overrides default substitutions
  a: "@"
  s: "$"

Run against it:

keygen-dictionary --config target.yaml

Save current session inputs to YAML for later reuse:

keygen-dictionary --name "John Doe" --date 01-01-1990 --config-save target.yaml

CLI flags override config values when both are provided.

---

Output

Candidates are written one per line to pass.txt (or --output FILE).

With --entropy-sort / interactive sort prompt accepted, candidates are reordered ascending by Shannon entropy — predictable, human-chosen patterns appear first. This improves hit rate when using the list in a sequential attack.

All flags

usage: keygen-dictionary [-h] [--version] [--config FILE]
                         [--config-save FILE] [-q]
                         [--name NAME] [--domain DOMAIN] [--address ADDR]
                         [--date DATE] [--id ID] [--additional DATA]
                         [--level N] [--min-length N] [--max-length N]
                         [--output FILE] [--entropy-sort] [--dry-run]
                         [--leet MAP]

options:
  --config FILE      Load target data from YAML config file
  --config-save FILE Save collected inputs to YAML after loading
  -q, --quiet        Suppress all output except final line count

target data (overrides --config):
  --name NAME        Full name (repeatable)
  --domain DOMAIN    Domain URL (repeatable)
  --address ADDR     Address (repeatable)
  --date DATE        Date dd-mm-yyyy (repeatable)
  --id ID            ID number (repeatable)
  --additional DATA  Additional keyword (repeatable)

generation options:
  --level N          Combination level (default: 2)
  --min-length N     Min password length
  --max-length N     Max password length
  --output FILE      Output file (default: pass.txt)
  --entropy-sort     Sort output by entropy (RAM-heavy)
  --dry-run          Show token/candidate count without generating
  --leet MAP         Custom leet substitutions e.g. "a:@,e:3,s:$"
