powershell 更新 IIS SSL 证书

powershell 更新 IIS SSL 证书

Intro

最近发现我们开发环境的 IIS 上的 SSL 证书过期了，为了后面方便维护和更新，搞了一个 powershell 脚本，以后要更新的时候直接跑一下脚本就可以了，所以有了这篇文章

Solution

更新过程：

1. 移除之前老的证书
2. 导入新的证书
3. 移除旧的 ssl 证书
4. 创建新的 ssl 证书绑定新的证书

完整的更新脚本如下：

$hostName = "xxx.com"

$pfxCertPath = "C:\backup\xxxxx.pfx"
$pfxCertPwdPath = "C:\backup\pfx-password.txt"
$certImportPwd = Get-Content $pfxCertPwdPath | ConvertTo-SecureString -AsPlainText -Force

# try remove before ssl certs
Get-ChildItem "cert:\LocalMachine\My" | where-object { $_.Subject -like "*$hostName*" }  | Remove-Item

# import new ssl 
$importedCert = Import-PfxCertificate -FilePath $pfxCertPath -CertStoreLocation "Cert:\LocalMachine\My" -p $certImportPwd

$certHash = $importedCert.Thumbprint

# remove sslcert binding
netsh http delete sslcert hostnameport="${hostName}:443"

# add new sslcert binding
$guid = [guid]::NewGuid().ToString("B")
netsh http add sslcert hostnameport="${hostName}:443" certhash=$certHash certstorename=MY appid="$guid"
