I need the following check for strong password validation:
I found and tweaked a RegEx and it's like this (sorry, I lost the reference...):
^.*(?=.{7,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@'#.$;%^&+=!""()*,-/:<>?]).*$
It's working in C#
except for the fact that I need to match any special char, and I really mean ANY . In other words, I need that the "special char" be anything but numbers and lower/uppercase letters.
For the sake of clarity, let's consider that accents are special chars, so é
, ñ
and the like should be considered special chars in the context of this question.
^.*(?=.{7,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[^a-zA-Z0-9]).*$
(Not C# code)
def validate (value):
return (value.Length >= 7 &&
value.IndexOfAny(['0', ..., '9']) >= 0 &&
value.IndexOfAny(['A', ..., 'Z']) >= 0 &&
value.IndexOfAny(['@', ..., ')']));
Yes I know this is not what the question required, but I believe it's much clearer, have higher performance and easier to maintain than any RegExp solution.
I believe that :-
\\w
Matches any word character.
The inverse is :-
\\W
Which is what you want.
Edit
^.*(?=.{7,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\W_]).*$
Test your regular expressions at :-
看看这里: Unicode正则表达式并选择一个Unicode类,如\\p{Symbol}
或\\p{Punctuation}
尝试这个:
^(?=.{7,})(?=.*?\d)(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[@'#.$;%^&+=!"()*,-/:<>?])
