Im working on javascript regex which includes having following conditions. So far with no luck.
-The minimum character count allowed is 8.
-The maximum character count allowed is 64.
-The entered text should include at least two of the following – numbers, lowercase letters, uppercase letters, Special characters.
-Entering symbols will not be supported.
So far what I have is this @anubhava answer here.
^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,63}$
This regex will enforce these rules:
-At least one upper case English letter, (?=.*?[A-Z])
-At least one lower case English letter, (?=.*?[a-z])
-At least one digit, (?=.*?[0-9])
-At least one special character, (?=.?[#?!@$%^&-])
-Minimum eight in length .{8,63} (with the anchors)
My Question is how do I satify my 3rd and 4th conditions Which is :-
-The entered text should include at least two of the following – numbers, lowercase letters, uppercase letters, Special characters.
-Entering symbols will not be supported.
Any help would be appreciated.

^(?!.*[^A-Za-z0-9#?!@$%^&*-]$)(?![a-z]*$)(?![A-Z]*$)(?![0-9]*$)(?![#?!@$%^&*-]*$).{8,64}$The string should not contain any symbol outside the 4 groups of characters
^(?!.*[^A-Za-z0-9#?!@$%^&*-]$)The string should not consist only of lower letters
(?![a-z]*$)The string should not consist only of upper letters
(?![A-Z]*$)The string should not consist only of digits
(?![0-9]*$)The string should not consist only of special characters
(?![#?!@$%^&*-]*$)The string should consist of 8 to 64 characters

If the string should contain symbols of at list 3 groups of 4
^(?!.*[^A-Za-z0-9#?!@$%^&*-]$)((?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])|(?=.*[a-z])(?=.*[A-Z])(?=.*[#?!@$%^&*-])|(?=.*[a-z])(?=.*[0-9])(?=.*[#?!@$%^&*-])|(?=.*[A-Z])(?=.*[0-9])(?=.*[#?!@$%^&*-])).{8,64}$The string should not contain any symbol outside the 4 groups of characters
^(?!.*[^A-Za-z0-9#?!@$%^&*-]$)Then 4 variants of 3 groups of 4 that the symbols should be member of:
(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])or
(?=.*[a-z])(?=.*[A-Z])(?=.*[#?!@$%^&*-])or
(?=.*[a-z])(?=.*[0-9])(?=.*[#?!@$%^&*-])or
(?=.*[A-Z])(?=.*[0-9])(?=.*[#?!@$%^&*-])and finally the string should consist of 8 to 64 characters
.{8,64}$
