Entropy Information
Entropy measures the randomness and unpredictability of your strings:
- Low (< 40 bits): Weak - suitable for non-critical uses
- Medium (40-60 bits): Moderate - good for general purposes
- High (60-80 bits): Strong - recommended for passwords
- Very High (> 80 bits): Very strong - suitable for high-security applications
