用于密码验证的正则表达式(正则表达式) [英] Regex (regular expression) for password validation
问题描述
什么是正确的regex，以满足以下密码条件:
What would be the correct regex, to satisfy the following password criteria:
- 必须至少包含1个小写字母.
- 必须至少包含1个大写字母.
- 必须至少包含1个数字.
- 必须至少包含1个特殊字符(仅允许使用以下特殊字符:
!#%). - 除
A-Za-z0-9!#%之外，不得包含任何其他字符(例如，不得包括;). - 长度必须在8到32个字符之间.
- Must include at least 1 lower-case letter.
- Must include at least 1 upper-case letter.
- Must include at least 1 number.
- Must include at least 1 special character (only the following special characters are allowed:
!#%). - Must NOT include any other characters then
A-Za-z0-9!#%(must not include;for example). - Must be from 8 to 32 characters long.
这是我尝试过的方法，但是不起作用:
This is what i tried, but it doesn't work:
^(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[0-9])(?=.*?[\!\#\@\$\%\&\/\(\)\=\?\*\-\+\-\_\.\:\;\,\]\[\{\}\^]).{8,32}
但是应该是:
^(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[0-9])(?=.*?[\!\#\@\$\%\&\/\(\)\=\?\*\-\+\-\_\.\:\;\,\]\[\{\}\^])[A-Za-z0-9!#%]{8,32}
但是无论如何，Unihedron的解决方案还是更好的，只是想为那些将来会阅读此问题的用户提及这一点. :)
But Unihedron's solution is better anyways, just wanted to mention this for the users which will read this question in the future. :)
Unihedron的解决方案(也可以在下面的答案中找到，我为自己复制了它，以防万一他更改(将其更新为更好的版本)在他的答案中):
Unihedron's solution (can also be found in his answer below, i copied it for myself, just in case he changes (updates it to an better version) it in his answer):
^(?=[^a-z]*[a-z])(?=[^A-Z]*[A-Z])(?=\D*\d)(?=.*?[!#%])[A-Za-z0-9!#%]{8,32}$
我得到了以下regex:
^(?=[^a-z]*[a-z])(?=[^A-Z]*[A-Z])(?=\D*\d)(?=.*?[\!\#\@\$\%\&\/\(\)\=\?\*\-\+\-\_\.\:\;\,\]\[\{\}\^])[A-Za-z0-9\!\#\@\$\%\&\/\(\)\=\?\*\-\+\-\_\.\:\;\,\]\[\{\}\^]{8,60}$
再次感谢Unihedron和skamazin.感激！
Thanks again Unihedron and skamazin. Appreciated!
推荐答案
使用此正则表达式:
/^(?=[^a-z]*[a-z])(?=[^A-Z]*[A-Z])(?=\D*\d)(?=[^!#%]*[!#%])[A-Za-z0-9!#%]{8,32}$/
这是一个 regex演示！
