我尝试使用" Self"在 KeyVault中创建自签名证书。发行者。
$policy = New-AzureKeyVaultCertificatePolicy -SubjectName "CN=$($certificateName)" -IssuerName "Self" -ValidityInMonths 12
$policy.Exportable = $true
Add-AzureKeyVaultCertificate -VaultName $vaultName -Name $certificateName -CertificatePolicy $policy
然而,当获得证书时,它似乎没有私钥。
直接在KeyVault中创建证书似乎并没有在线,在深入研究了PowerShell cmdlet的其余API文档和源代码之后,我很难解决。
我希望我能错过一些简单的事情,因为我希望避免在本地创建证书..

如果您想要检索证书及其私钥,则可以通过以下方式将其导出到磁盘上的PFX文件(使用空密码):
$vaultName = "my-vault-name"
$certificateName = "my-cert-name"
$pfxPath = [Environment]::GetFolderPath("Desktop") + "\$certificateName.pfx"
$pfxSecret = Get-AzureKeyVaultSecret -VaultName $vaultName -Name $certificateName
$pfxUnprotectedBytes = [Convert]::FromBase64String($pfxSecret.SecretValueText)
[IO.File]::WriteAllBytes($pfxPath, $pfxUnprotectedBytes)
如果您想在内存中查看私钥本身而不写入磁盘,请尝试:
$vaultName = "my-vault-name"
$certificateName = "my-cert-name"
$pfxPath = [Environment]::GetFolderPath("Desktop") + "\$certificateName.pfx"
$pfxSecret = Get-AzureKeyVaultSecret -VaultName $vaultName -Name $certificateName
$pfxUnprotectedBytes = [Convert]::FromBase64String($pfxSecret.SecretValueText)
$pfx = New-Object Security.Cryptography.X509Certificates.X509Certificate2
$pfx.Import($pfxUnprotectedBytes, $null, [Security.Cryptography.X509Certificates.X509KeyStorageFlags]::Exportable)
$pfx.PrivateKey.ExportParameters($true)
除了指数和模数外,还将显示私有参数。
如果您想使用自己的密码保护磁盘上的PFX文件(根据"检索pfx文件&添加密码" this blog post中的说明),则尝试:
$vaultName = "my-vault-name"
$certificateName = "my-cert-name"
$pfxPath = [Environment]::GetFolderPath("Desktop") + "\$certificateName.pfx"
$password = "my-password"
$pfxSecret = Get-AzureKeyVaultSecret -VaultName $vaultName -Name $certificateName
$pfxUnprotectedBytes = [Convert]::FromBase64String($pfxSecret.SecretValueText)
$pfx = New-Object Security.Cryptography.X509Certificates.X509Certificate2
$pfx.Import($pfxUnprotectedBytes, $null, [Security.Cryptography.X509Certificates.X509KeyStorageFlags]::Exportable)
$pfxProtectedBytes = $pfx.Export([Security.Cryptography.X509Certificates.X509ContentType]::Pkcs12, $password)
[IO.File]::WriteAllBytes($pfxPath, $pfxProtectedBytes)
如REST API文档here和here中所述,Azure Key Vault(AKV)通过三个相互关联的资源代表给定的X.509证书:AKV证书,AKV密钥,和一个AKV秘密。这三个将共享相同的名称和相同的版本 - 为了验证这一点,请检查来自Id
的响应中的KeyId
,SecretId
和Get-AzureKeyVaultCertificate
属性。
这三种资源中的每一种都为查看给定的X.509证书提供了不同的视角:
n
和e
),以及其他证书元数据(指纹,有效期,主题名称等)。在PowerShell中,您可以通过以下方式获取此信息:(Get-AzureKeyVaultCertificate -VaultName $vaultName -Name $certificateName).Certificate
(Get-AzureKeyVaultKey -VaultName $vaultName -Name $certificateName).Key
(Get-AzureKeyVaultSecret -VaultName $vaultName -Name $certificateName).SecretValueText

以下是C#代码,可在给定证书名称和KeyVault连接信息的情况下,从最新到最旧检索证书的所有版本,包括其私钥。它使用新的Azure.Core
,Azure.Identity
和Azure.Security.KeyVault.[Certificates|Secrets]
SDK软件包。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using Azure.Core;
using Azure.Identity;
using Azure.Security.KeyVault.Certificates;
using Azure.Security.KeyVault.Secrets;
public static class CertTools
{
public static void MyMethod(string tenantId, string clientId, string clientSecret, Uri keyVaultUri)
{
var cred = new ClientSecretCredential(tenantId, clientId, clientSecret); // or any other means of obtaining Azure credential
var certs = GetAllCertificateVersions(keyVaultUri, cred, "MyCert");
}
public static List<X509Certificate2> GetAllCertificateVersions(Uri keyVaultUri, TokenCredential credential,
string certificateName)
{
var certClient = new CertificateClient(keyVaultUri, credential);
var secretClient = new SecretClient(keyVaultUri, credential);
var now = DateTimeOffset.UtcNow;
var certs = new List<X509Certificate2>();
foreach (var cert in certClient.GetPropertiesOfCertificateVersions(certificateName)
.OrderByDescending(x => x.CreatedOn)
// fetch all enabled, non-expired certificates. adjust this predicate if desired.
.Where(x => x.ExpiresOn >= now && (x.Enabled ?? false)))
{
var secret = secretClient.GetSecret(certificateName, cert.Version).Value;
certs.Add(new X509Certificate2(Convert.FromBase64String(secret.Value)));
}
return certs;
}
}
感谢@Nandun's answer here为我指明了使用SecretClient而不是CertificateClient的正确方向,但是该帖子被标记为重复,因此请在此处发布此扩展代码。
