检查服务器支持的Security protocol powershell

最近开发遇见一个《  his could be due to the fact that the server certificate is not configured property with HTTP.SYS in the HTTPS case》问题。

由于服务半年没有部署修改过，突然提示错误，查阅相关文档了解到，服务器关闭了TLS10安全协议。一下是检查服务器TLS支持协议版本号的Powershell脚本

脚本来源：

function Test-ServerSSLSupport {
[CmdletBinding()]
    param(
        [Parameter(Mandatory = $true, ValueFromPipeline = $true)]
        [ValidateNotNullOrEmpty()]
        [string]$HostName,
        [UInt16]$Port = 443
    )
    process {
        $RetValue = New-Object psobject -Property @{
            Host = $HostName
            Port = $Port
            SSLv2 = $false
            SSLv3 = $false
            TLSv1_0 = $false
            TLSv1_1 = $false
            TLSv1_2 = $false
            KeyExhange = $null
            HashAlgorithm = $null
        }
        "ssl2", "ssl3", "tls", "tls11", "tls12" | %{
            $TcpClient = New-Object Net.Sockets.TcpClient
            $TcpClient.Connect($RetValue.Host, $RetValue.Port)
            $SslStream = New-Object Net.Security.SslStream $TcpClient.GetStream(),
                $true,
                ([System.Net.Security.RemoteCertificateValidationCallback]{ $true })
            $SslStream.ReadTimeout = 15000
            $SslStream.WriteTimeout = 15000
            try {
                $SslStream.AuthenticateAsClient($RetValue.Host,$null,$_,$false)
                $RetValue.KeyExhange = $SslStream.KeyExchangeAlgorithm
                $RetValue.HashAlgorithm = $SslStream.HashAlgorithm
                $status = $true
            } catch {
                $status = $false
            }
            switch ($_) {
                "ssl2" {$RetValue.SSLv2 = $status}
                "ssl3" {$RetValue.SSLv3 = $status}
                "tls" {$RetValue.TLSv1_0 = $status}
                "tls11" {$RetValue.TLSv1_1 = $status}
                "tls12" {$RetValue.TLSv1_2 = $status}
            }
            # dispose objects to prevent memory leaks
            $TcpClient.Dispose()
            $SslStream.Dispose()
        }
        $RetValue
    }
}

调用示例：

"www.baidu.com" Test-ServerSSLSupport

由于默认是访问的443端口，如果443没有启动可以在代码中修改$Port
