regex to restrict special characters except few

Question

I was able to write a regex to validate the below criterias for an input box.

1. contain minimum of 14 characters
2. contain at least 1 capital letter (A-Z)
3. contain at least 1 simple letter (a-z)
4. contain at least 1 number (0-9)
5. contain at least 1 special symbol (+=!@#$%^&*)

Regex -> ^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[+=!@#$%^&*])(?=\\S+$).{14,}$

However, this regex allows other special characters which are not mentioned. I want to restrict all the special characters except these +=!@#$%^&*

could someone help me to modify the given regex with the above criteria?

Answer 1

Instead of . that allows any character you can use a character set to restrict the allowed characters to a specific set:

^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[+=!@#$%^&*])(?=\\S+$)[0-9A-Za-z+=!@#$%^&*]{14,}$
