Azure-CLI/Powershell密码要求 [英] Azure-CLI/Powershell Password requirments

问题描述

因此，我正在尝试使一个变量与在Azure命令行中制作虚拟机的密码要求相符

So i am trying to make a variable match the password requirements for making a virtual machine in azure CLI

要执行此操作，必须使用以下三个大写字母，1个小写字母，1个特殊字符或数字

to do this it must have 3 of the following !uppercase, 1 lowercase 1 special character or a number

这是我要更改的主要代码

This is the main code i am trying to change

$AdminPassword = Read-Host -Prompt "Please insert a Admin Password (Password must have 3 of the following: 1 lower case character, 1 upper case character, 1 number and 1 special character)"

这是我更改的代码，但无法正常工作

This is the code i changed but isn't working correctly

do 
    {
        $AdminPassword = Read-Host -Prompt "Please insert a Admin Password (Password must have the 3 of the following: 1 lower case character, 1 upper case character, 1 number and 1 special character)"
    }
    until($AdminPassword -Like "[A-Z][A-Z][A-Z][a-z][a-z][a-z][0-9][0-9][0-9][!@$#$%^&*()_+\-=\[\]{};'':"\\|,.<>\/? ][!@$#$%^&*()_+\-=\[\]{};'':"\\|,.<>\/? ][!@$#$%^&*()_+\-=\[\]{};'':"\\|,.<>\/? ]")
    Write Match

使用写匹配行，我知道它何时成功

with the write match line i know when it succeeds

我这里真正的麻烦是我要全部4个要求都3遍，所以3个大写字母3个小写字母等等 而且我也想拥有特殊字符 但是#注释所有后续代码

the real trouble i have here is that i want all 4 of the requirements 3 times so 3 uppercase's 3 lowercase's etc and i also want to have the special characters but the # comments all the code that follows out

推荐答案

我不确定是否可以仅使用一个正则表达式来完成. 或者，可以在下面的一个小助手功能下进行测试.

I'm not sure if this can be done with just one regex.. As an alternative, below a small helper function to do the tests.

function Test-AdminPassword {
    [CmdletBinding()]
    Param(
        [Parameter(Position = 0, Mandatory=$true)]
        [string]$Password,

        [Parameter(Position = 1)]
        [int]$Requirements = 5
    )
    $result = 0

    # test length between 12 and 24
    if ($Password.Length -in 12..24) {
        $result++
    }
    # test uppercase
    if (($Password -creplace '[^A-Z]', '').Length -ge 3) {
        $result++
    }
    # test lowercase
    if (($Password -creplace '[^a-z]', '').Length -ge 3) {
        $result++
    }
    # test digits
    if (($Password -replace '[^0-9]', '').Length -ge 3) {
        $result++
    }
    # test special characters
    if (($Password -creplace '[^!@$#%^&*()_+\-=\[\]{};'':"\\|,.<>\/? ]', '').Length -ge 3) {
        $result++
    }

    # return $true if the password complies with at least $requirements
    return ($result -ge $Requirements)
}

do {
    $AdminPassword = Read-Host -Prompt "Please insert an Admin Password (must have the 3 lower case characters, 3 upper case characters, 3 digits and 3 special characters)"
} until (Test-AdminPassword $AdminPassword)
