强密码的正则表达式 [英] Strong password regex

问题描述

我需要强大的密码验证的正则表达式

 特殊字符 - 不允许
空间 - 不允许
数字字符 - 至少有一个字符
至少有一个大写字母
场的最小和最大长度 -  6到12个字符
重复的字符 - 允许只有两个重复的字符
 

我的正则表达式是 ^（？=。* \\ D）（？=。* [AZ]）（？=。* [AZ]）（？！。* \\ S）（？= （？：？！（\\ W）（\\ 1 {2}））+）{6,12} $
但是却忽略了特殊字符（如加？）

请帮帮忙！

解决方案

  ^（？=。* [AZ]）（？=。* \\ D）（？！。*（ 。）\\ 1 \\ 1）[A-ZA-Z0-9 @] {6,12} $
 

• 特殊字符 - 不允许


• 空间 - 不允许


• 最小和领域的最大长度 - 6到12个字符结果
  通过满足[A​​-ZA-Z0-9 @] {6,12}


• 数字字符 - 至少有一个字符结果
  由<一个满足href=\"http://stackoverflow.com/questions/2973436/regex-lookahead-lookbehind-and-atomic-groups/2973609#2973609\">positive前瞻 （？=。* \\ D）


• 在至少一个大写字母搜索
  通过积极的前瞻满足（？=。* [A-Z]）


• 重复字符 - 允许只有两个重复的字符结果
  我不知道你这个是什么意思。负前瞻（？！*（。）\\ 1 \\ 1）确保没有字符被允许在连续出现两次以上。子 AA 是好的， AAA 不是。结果
  让（？！*（。+）\\ 1 \\ 1）拒绝长度的重复子不止一个（如 ABABAB ）或添加。* 在 \\ 1 拒绝非连续多次出现过。

I need strong password validation regex

Special Characters - Not Allowed
Spaces - Not Allowed
Numeric Character - At least one character
At least one Capital Letter 
Minimum and Maximum Length of field - 6 to 12 Characters
Repetitive Characters - Allowed only two repetitive characters

my Regex is ^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?!.*\s)(?=(?:(\w)(?!\1{2}))+).{6,12}$ but it ignores special characters (where to add?)

Please help!

解决方案

^(?=.*[A-Z])(?=.*\d)(?!.*(.)\1\1)[a-zA-Z0-9@]{6,12}$

• Special Characters - Not Allowed
• Spaces - Not Allowed
• Minimum and Maximum Length of field - 6 to 12 Characters
  Met by [a-zA-Z0-9@]{6,12}
• Numeric Character - At least one character
  Met by positive lookahead (?=.*\d)
• At least one Capital Letter
  Met by positive lookahead (?=.*[A-Z])
• Repetitive Characters - Allowed only two repetitive characters
  I am not sure what you mean by this. The negative lookahead (?!.*(.)\1\1) makes sure that no character is allowed to appear more than two times in a row. Substring aa is okay, aaa is not.
  Make it (?!.*(.+)\1\1) to reject repeated substrings of length more than one (like ababab) or add .* before \1 to reject non-continuous repeated appearances too.
