🌟 Key Features

• 🔒 Cryptographically Secure - Uses Python's secrets module for true randomness
• ⚙️ Highly Configurable - Control length, character types, and minimum requirements
• 📊 Integrated Strength Rating - Built-in password strength assessment with entropy calculation
• 🛡️ Shell Safety Aware - Understands potentially problematic characters for shell environments
• 🔧 Multiple Interfaces - Use via CLI (cacao-pass) or Python API
• 🌐 Environment Variable Support - Configure defaults via CACAO_PW_* environment variables
• 📦 Zero Dependencies - No runtime dependencies, minimal footprint
• 🐍 Modern Python - Supports Python 3.8+

📦 Installation

Install from PyPI using pip:

pip install cacao-password-generator

---

⚡ Quick Start

CLI Usage

Generate a secure password with default settings:

cacao-pass

Generate a custom password:

cacao-pass --length 16 --minuchars 2 --minlchars 2 --minnumbers 2 --minschars 2

Python API Usage

from cacao_password_generator.core import generate

# Simple generation
password = generate(length=12)
print(password)  # e.g., "Kp9$mL2@Wq3z"

# With custom constraints
password = generate({
    'minuchars': 3,
    'minlchars': 3,
    'minnumbers': 2,
    'minschars': 2
}, length=16)

📚 Detailed Usage

🖥️ Command Line Interface

The cacao-pass command provides a full-featured CLI:

# Basic usage with length
cacao-pass --length 20

# Full constraint specification
cacao-pass \
  --length 16 \
  --minuchars 2 \
  --minlchars 3 \
  --minnumbers 2 \
  --minschars 1

# Get help
cacao-pass --help

CLI Options

Option	Short	Description	Default
--length	-l	Password length	12
--minuchars	-u	Minimum uppercase letters	1
--minlchars	-lc	Minimum lowercase letters	1
--minnumbers	-n	Minimum numbers	1
--minschars	-s	Minimum special characters	1

🐍 Python API

Basic Generation

from cacao_password_generator.core import generate

# Default secure password (length 12)
password = generate()

# Custom length
password = generate(length=20)

# With character requirements
password = generate({
    'minuchars': 3, # At least 3 uppercase
    'minlchars': 3,  # At least 3 lowercase
    'minnumbers': 2, # At least 2 numbers
    'minschars': 2   # At least 2 special chars
}, length=16)

Advanced Usage with Validation

from cacao_password_generator.core import generate
from cacao_password_generator.rating import rating
from cacao_password_generator.validate import validate

# Generate and validate
password = generate(length=16, minschars=3)

# Check if password meets requirements
is_valid, errors = validate(password, length=16, minschars=3)
print(f"Valid: {is_valid}")

# Get strength rating
strength_rating = rating(password)
print(f"Strength: {strength_rating}")  # e.g., "strong"

⚙️ Configuration

Default Settings

Parameter	Default	Description
length	12	Password length
minlen	6	Minimum allowed length
maxlen	128	Maximum allowed length
minuchars	1	Minimum uppercase letters
minlchars	1	Minimum lowercase letters
minnumbers	1	Minimum numbers
minschars	1	Minimum special characters

Environment Variables

Override defaults using environment variables with the CACAO_PW_ prefix:

export CACAO_PW_MINLEN=8
export CACAO_PW_MAXLEN=32
export CACAO_PW_MINUCHARS=2
export CACAO_PW_MINLCHARS=4
export CACAO_PW_MINNUMBERS=3
export CACAO_PW_MINSCHARS=2

# Now cacao-pass uses these defaults
cacao-pass

Character Sets

• Uppercase: A-Z (26 characters)
• Lowercase: a-z (26 characters)
• Numbers: 0-9 (10 characters)
• Special: !@#$%^&*()_+-=[]{}|;:,.<>? (25 characters)

💡 Examples

Web Application Passwords

# Strong password for user accounts
user_password = generate(length=14, minuchars=2, minlchars=6, minnumbers=2, minschars=4)

# API key style (longer, more entropy)
api_key = generate(length=32, minuchars=4, minlchars=8, minnumbers=8, minschars=4)

System Administration

# Database password (shell-safe considerations)
cacao-pass --length 20 --minschars 2

# SSH key passphrase
cacao-pass --length 25 --minuchars 3 --minlchars 8 --minnumbers 4

Batch Generation

from cacao_password_generator.core import generate

# Generate multiple passwords
passwords = [generate(length=16) for _ in range(10)]

# Generate with consistent strength
strong_passwords = [
    generate(length=18, minuchars=3, minlchars=6, minnumbers=3, minschars=6)
    for _ in range(5)
]

Password Strength Analysis

from cacao_password_generator.core import generate
from cacao_password_generator.rating import rating, detailed_rating

password = generate(length=20)
strength_rating = rating(password)
detailed_analysis = detailed_rating(password)

print(f"Password: {password}")
print(f"Strength: {strength_rating}")
print(f"Entropy: {detailed_analysis['entropy']:.2f} bits")
print(f"Character Space: {detailed_analysis['character_set_size']}")
print(f"Estimated Crack Time: {detailed_analysis['crack_time_formatted']}")
