    Use crypto/rand to generate cryptographically secure random passwords from the selected character sets.

  3. 03

    Score password strength

    ~1.5h

    Write a function estimating password strength based on entropy from length and character variety.

  4. 04

    Add batch mode

    ~1h

    Allow generating multiple passwords at once with a count flag.

  5. 05

    Write tests

    ~1h

    Test edge cases such as minimum length, empty character sets, and maximum entropy inputs.
