正则表达式验证密码强度 [英] Regex to validate password strength

问题描述

我的密码强度标准如下:

My password strength criteria is as below :

• 8 个字符长度
• 2 个大写字母
• 1 个特殊字符 (!@#$&*)
• 2 个数字 (0-9)
• 3 个小写字母

有人可以给我正则表达式吗?密码必须满足所有条件.

Can somebody please give me regex for same. All conditions must be met by password .

推荐答案

您可以使用积极的前瞻断言进行这些检查:

You can do these checks using positive look ahead assertions:

^(?=.*[A-Z].*[A-Z])(?=.*[!@#$&*])(?=.*[0-9].*[0-9])(?=.*[a-z].*[a-z].*[a-z]).{8}$

(?=.*[A-Z].*[A-Z])        Ensure string has two uppercase letters.
(?=.*[!@#$&*])            Ensure string has one special case letter.
(?=.*[0-9].*[0-9])        Ensure string has two digits.
(?=.*[a-z].*[a-z].*[a-z]) Ensure string has three lowercase letters.
.{8}                      Ensure string is of length 8.
