How to Use This Calculator
  1. Follow the step-by-step wizard — complete each step before moving to the next. This guided approach ensures you provide all the necessary information in a logical order.
  2. Tool Type — Calculation mode to use. Choose from: Password Strength Analysis, Password Generation Parameters, Hash/Encryption Info. default: 0.
  3. Password Length — Length of the shape or side. Accepts values from 1 to 128 (default: 12).
  4. Lowercase (a-z) — Include lowercase letters. Toggle this on or off depending on whether it applies to your situation. default: 1.
  5. Uppercase (A-Z) — Include uppercase letters. Toggle this on or off depending on whether it applies to your situation. default: 1.
  6. Numbers (0-9) — Include numbers. Toggle this on or off depending on whether it applies to your situation. default: 1.
  7. Symbols (!@#$...) — Include special characters. Toggle this on or off depending on whether it applies to your situation. default: 1.
  8. Target Entropy (bits) — Recommended: 80+ bits for high security. Accepts values from 28 to 256 (default: 80).
  9. Preferred Length — enter a numeric value. Accepts values from 8 to 64 (default: 16).
  10. Include Ambiguous Chars — 0, O, 1, l, I, | Toggle this on or off depending on whether it applies to your situation. default: 0.
  11. Hash Algorithm — enter your preferred option from the dropdown. Choose from: MD5 (Broken), SHA-1 (Deprecated), SHA-256 (Secure), SHA-512 (High Security), bcrypt (Password Hashing), Argon2 (Best Practice). default: 2.
  12. Expand "Advanced Options" for additional fine-tuning. These optional inputs let you model more specific scenarios:
  13. Avoid Common Patterns — Avoids dictionary words, sequences, repetition. Toggle this on or off depending on whether it applies to your situation. default: 1.
