Parameters:

  • length (Integer) (defaults to: 16) —

    The length of the string to generate

  • padding (Boolean) (defaults to: false) —

    Toggles if a final equal '=' will be added.

  • urlsafe (Boolean) (defaults to: true) —

    Toggles charset to '-' and '_' instead of '+' and '/'.

Returns:

  • (String)
