Password Hasher

$4.99

Secure password hashing toolkit with PBKDF2 (bcrypt-compatible work factors) and scrypt (Argon2-compatible memory hardness). Includes strength validation, breach detection via k-anonymity, timing-safe comparisons, and migration helpers. Runs on Python 3.10+ stdlib only.

• PBKDF2-SHA256 with configurable iterations (bcrypt-equivalent strength)
• Scrypt with tunable memory/CPU cost (Argon2-equivalent hardness)
• Password strength checker: length, complexity, entropy, common patterns
• Timing-safe comparison to prevent timing attacks
• Hash format versioning for algorithm migration
• CLI tool for hashing, verifying, and strength checking

# Hash a password with PBKDF2
python main.py hash --algorithm pbkdf2 --password "my-secure-password"

# Verify a password against a hash
python main.py verify --hash "$pbkdf2$..." --password "my-secure-password"

# Check password strength
python main.py strength --password "my-secure-password"
