createpw.exe (week #23)

Tuesday, June 4, 2013 Labels: Application of the Week 2013 , Utility

This is a simple utility to create unique passwords from a key (such as a website name) and a master password. The idea for the code came from ss64.com.

USAGE: createpw.exe [options] [key|site-name]

  key|site-name      Any unique key that you will remember.
                     If you’re using this for a website, put in
                     the url (such as: amazon or amazon.com).
                     If omitted, you will be prompted for it.

OPTIONS: 

  --clip             Put the newly created password onto the clipboard. 
                     This is the default behavior.
  --no-clip          Output the new password to the console.
  --no-symbols       Do not output symbols in the new password.

When it asks for the user name, you can just press enter to bypass/skip it. JUST be sure that you are consistent in supplying a user name with keys or not.

Here are a couple of examples:

    $ createpw amazon.com
    Enter the username:         user
    Enter the master password:  ********

    password = (put into clipboard)

    $ createpw
    Enter the site name or key: amazon.com
    Enter the username:         user
    Enter the master password:  ********

    password = (put into clipboard)

    $ createpw --no-clip
    Enter the site name or key: amazon.com
    Enter the username:         user
    Enter the master password:  ********

    password = #ZJ~EEUmXuYVdMEMUK7CVbgxqY

For the last example I typed `12345678` for the password. You should get the same result!
