Secure Password Generator

Generate cryptographically secure passwords, passphrases, and API keys. Supports multiple formats and entropy calculation.

Generate cryptographically secure passwords, passphrases, and API keys. Uses secrets module (CSPRNG) — not random.

Quick Start

# Generate a 20-char password
python3 {baseDir}/scripts/passgen.py

# Generate a passphrase
python3 {baseDir}/scripts/passgen.py --type passphrase --words 5
