用于检查密码标准的PowerShell脚本

Question

我正在研究一个创建本地帐户的脚本，为用户提供了两次输入密码的机会，然后将根据类似于网络帐户的标准进行审查。 我已经整理了下面的脚本，可以几乎可以做到这一点。这似乎有能力遵守我要插入的某些标准。

我正在寻找的是比较第一个和确认条目并检查它们与以下组合所输入的内容，如果他们不拒绝它们，请拒绝它们。 t满足标准并接受它们，如果他们这样做：

至少1 x大写字母，至少1 x特殊字符，至少1 x数字，至少8个字符 - 例如“ monkeypuzzle1！”

至少1 x特殊字符，至少1 x数字，至少8个字符 - 例如“ monkeypuzzle1！”

至少1 x大写字母，1 x小写字母，至少1个特殊字符，至少8个字符 - 例如“ monkeypuzzle！”

至少1 x大写字母，1 x小写字母，至少1 x数字，至少8个字符 - “ monkeypuzzle1”，

我到目前为止已经成功比较了第一个条目和确认条目，并且似乎能够仔细检查 1 x帽，1 x小写，1 x特殊，1 x数字，8个字符标准和 1 x帽，1x小写，1 x数字，1 x，8个字符标准，但不是另外两个。我尝试了几种方法，到目前为止，我无法破解它。

while($true)
{
        try
        {
            # Loop until a valid password is entered.

            $Entered_Password_01 = Read-Host "Enter a password: "-AsSecureString
            $Entered_Password_01_text = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($Entered_Password_01))
            Write-Host ""
            $Pass_criteria_01 = (-not(($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text.length -ge 7) -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '\d')))
            $Pass_criteria_02 = (-not(($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text.length -ge 7) -and ($Entered_Password_01_text -match '\d') -and ($Entered_Password_01_text -match '!|@|#|%|^|&|$')))
            $Pass_criteria_03 = (-not(($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text.length -ge 7) -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '!|@|#|%|^|&|$')))
            $Pass_criteria_04 = (-not(($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text.length -ge 7) -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '\d') -and ($Entered_Password_01_text -match '!|@|#|%|^|&|$')))
            if (        $Pass_criteria_01 -or
                        $Pass_criteria_02 -or
                        $Pass_criteria_03 -or
                        $Pass_criteria_04)
            {throw}
            $Entered_Password_02 = Read-Host "Confirm password: "-AsSecureString
            $Entered_Password_02_text = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($Entered_Password_02))
            Write-Host ""
            if ($Entered_Password_01_text -ceq $Entered_Password_02_text) {Write-host "successful test"}
            Else
            {throw}
            break
        }
        catch
        {
            Write-Host ""
            Write-Host "Invalid Password." -ForegroundColor Red
        }
}

我基本上试图告诉它，以根据4组标准对其进行顺序检查，如果它不测量并允许它弄清楚，则可以通过。

如果有人对如何实现这一目标有任何建议，请告诉我。

干杯。

在 mklement0的答案上的扩展似乎完成了这项工作，似乎已经通过了我目前能想到的所有测试，不得不通过寻找竞技场的角色来修改我寻找特殊角色的方法。 T大写，小写或数字。但是这个算是黄金！

$Entered_Password_01_text = 'Monkeypuzzle1!' # Experiment with different values here.
$Special_Chars = "[^a-zA-Z0-9]" #check for special characters, by looking for not regular characters or numbers.
$Password_Criteria = (
  (
                (($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '\d')),                                                         # At least 1 x lowercase, at least 1 x uppercase, at least 1 x number and 8 characters.
                (($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text -match '\d') -and ($Entered_Password_01_text -cmatch $Special_Chars)),                                                  # At least 1 x lowercase, at least 1 x number, at least 1 x special characters and 8 characters.
                (($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -cmatch $Special_Chars)),                                              # At least 1 x lowercase, at least 1 x uppercase, at least 1 x special characters and 8 characters.
                (($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '\d') -and ($Entered_Password_01_text -cmatch $Special_Chars)),                                                  # At least 1 x uppercase, at least 1 x number, at least 1 x special characters and 8 characters.
                (($Entered_Password_01_text -cmatch '[a-z]') -and ($Entered_Password_01_text -cmatch '[A-Z]') -and ($Entered_Password_01_text -match '\d') -and ($Entered_Password_01_text -cmatch $Special_Chars))  # At least 1 x lowercase, at least 1 x uppercase, at least 1 x number, at least 1 x special characters and 8 characters.
  ) -eq $true
).Count

$Password_Complexity_Validated = $Entered_Password_01_text.Length -ge 8 -and $Password_Criteria -ge 1

if (-not $Password_Complexity_Validated) { Write-host  'Invalid password.' -ForegroundColor Red
}Else{
Write-host 'Password is valid.'-ForegroundColor Green }

仅关注核心逻辑，请尝试以下操作：

$Entered_Password_01_text = 'foooooo1!' # Experiment with different values here.

$numCriteriaMet = (
  (
    ($Entered_Password_01_text -cmatch '[A-Z]'),     # at least 1 uppercase letter
    ($Entered_Password_01_text -match '[!@#%^&$]'),  # at least 1 special char.
    ($Entered_Password_01_text -match '[0-9]')       # at least 1 digit
  ) -eq $true
).Count

# A password is valid if it is at least 8 chars. long
# and meets at least 2 of the 3 criteria above.
$validOverall = $Entered_Password_01_text.Length -ge 8 -and $numCriteriaMet -ge 2

if (-not $validOverall) { throw 'Invalid password.' }

Write-Verbose -Verbose 'Password is valid.'
