Password Checker from CMD

Windows Batch File (.bat) · Notepad · Command Prompt

I created a simple password-checking project using a Windows batch file written in Notepad and run through Command Prompt. The exact features still need to be confirmed, so I present it as an introductory scripting project.

  • Tools: Windows, Notepad, Command Prompt
  • Focus: basic batch scripting and command-line use
  • Next step: document the exact features and improve the program
