Strong passwords validation laravel

So before any one shuts this down, I am referencing an answer and asking a question here.

So the question I have is I want a strong password validation for laravel, something that includes 10 character, numbers, upper lower case, so on and so forth.

I found it: https://stackoverflow.com/a/31549892/1270259

The problem is, this regex looks off:

/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\X])(?=.*[!$#%]).*$/

And since I am not good with regex I thought I would ask how can I fix it such that it validates:

  • Must be 10 characters long
  • Must contain upper and lower case
  • Must contain at least one number
  • Must contain at least one special character.

I feel like they were close in the answer. When this is run against github actions the error that comes back is preg_match(): Compilation failed: escape sequence is invalid in character class at offset 46.

Any thoughts as too how I can make this work for Laravel 7 to match the above constraints?

Use the principle of contrast:

^
(?=[^a-z]*[a-z]) # ensure one lower case letter
(?=[^A-Z]*[A-Z]) # ensure one upper case letter
(?=\D*\d)        # ensure a digit
(?=[^!@?]*[!@?]) # special chars
.{10,}           # at least 10 characters long
$

You can extend the special char section, of course.
