我正在使用 dotnet core 構建一個證書，如下所示： private X509Certificate2 buildSelfSignedServerCertificate(string CertificateName,string password,string dns) { SubjectAlternativeNameBuilder sanBuilder = new SubjectAlternativeNameBuilder(); sanBuilder.AddIpAddress(IPAddress.Loopback); sanBuilder.AddIpAddress(IPAddress.IPv6Loopback); if (!string.IsNullOrEmpty(dns)) { sanBuilder.AddDnsName(dns); } // // sanBuilder.AddDnsName(Environment.MachineName); X500DistinguishedName distinguishedName = new X500DistinguishedName($"CN={CertificateName}"); using (RSA rsa = RSA.Create(2048*2)) { var request = new CertificateRequest(distinguishedName, rsa, HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1); //request.CertificateExtensions.Add( // new X509KeyUsageExtension(X509KeyUsageFlags.DataEncipherment | X509KeyUsageFlags.KeyEncipherment | X509KeyUsageFlags.DigitalSignature, false)); //request.CertificateExtensions.Add( // new X509EnhancedKeyUsageExtension( // new OidCollection { new Oid("1.3.6.1.5.5.7.3.1"), new Oid("1.3.6.1.5.5.7.3.2") }, false)); request.CertificateExtensions.Add(sanBuilder.Build()); var certificate = request.CreateSelfSigned(new DateTimeOffset(DateTime.UtcNow.AddDays(-1)), new DateTimeOffset(DateTime.UtcNow.AddDays(3650))); bool isWindows = System.Runtime.InteropServices.RuntimeInformation .IsOSPlatform(OSPlatform.Windows); } }并且它不適用于服務結構，并且從我讀到的以下評論中：如果輸出包含如下內容： Provider = Microsoft Software Key Storage Provider 那么這確實是 CNG 證書（由 Key Storage Provider 頒發）。我認為證書是使用 New-SelfSignedCertificate PowerShell cmdlet 創建的，除非另有說明，否則它將使用 CNG 提供程序。如果是這種情況，并且您可以創建另一個用于此集群的證書，您可以嘗試以下操作：證書輸出看起來像這樣，確實提供者是錯誤的。有沒有辦法修復我上面的 c# 方法來解決這個問題？使用“Microsoft 增強型 RSA 和 AES 加密提供程序”

答案取決于您要對證書做什么。
PersistKeySet 行為
如果您想將其添加到X509Store它將“永遠”保持的位置（因此您將其作為帶有PersistKeySet標志的 PFX 導入），那么自我發現的解決方案是正確的：
using (RSA rsa = new RSACryptoServiceProvider(4096, new CspParameters(24, "Microsoft Enhanced RSA and AES Cryptographic Provider", Guid.NewGuid().ToString())))
{
CertificateRequest req = ...;
return req.CreateSelfSigned(...);
}
最重要的是，密鑰被賦予了名稱 ( Guid.NewGuid().ToString())，使其成為持久密鑰。這允許對cert.CopyWithPrivateKey埋在里面的調用CreateSelfSigned附加到磁盤上的鍵上。
EphemeralKeySet 行為，具有受控的 PFX 導出
如果您對該方法的唯一調用是將其導出到 PFX，那么您希望做的事情略有不同。
using (RSACryptoServiceProvider rsa = <same as above>)
{
// Delete this key on Dispose / finalization.
rsa.PersistKeyInCsp = false;
CertificateRequest req = ...;
using (X509Certificate2 cert = req.CreateSelfSigned(...))
{
// At this line the persisted key still exists so it reports its name and CSP/KSP into the PFX.
return cert.Export(X509ContentType.Pkcs12, password);
}
}
再次，密鑰被命名，使 CSP 和名稱保留在 PFX/PKCS12 中。但是該對象被標記為自刪除，因此它會自行清理。
如果您當時返回證書而不是導出，則證書將不再能夠使用其私鑰，并且以后的 PFX 導出將失敗。
“PerphemeralKeySet”行為證書
如果您想暫時使用證書，并控制 PFX 導出，并且密鑰不會永遠存在...結合前兩件事。
using (RSACryptoServiceProvider rsa = ...)
{
rsa.PersistKeyInCsp = false;
CertificateRequest req = ...;
using (X509Certificate2 cert = req.CreateSelfSigned(...))
{
// Export the PFX using the current key. Re-import it with no flags to
// make it a normal "perphemeral" key behavior.
return new X509Certificate2(cert.Export(X509ContentType.Pkcs12), "", X509KeyStorageFlags.Exportable);
}
}
此處的 PFX 導入，因為它發生在原始密鑰被釋放/刪除之前，它會移動到基于 GUID 的新密鑰名稱。如果您關心使用相同的名稱，請byte[]在讓 Dispose 調用密鑰對象之前導出到 a，然后重新導入，并且將使用相同的密鑰名稱（在所有當前版本的 Windows 上）......但現在刪除語義與證書的生命周期而不是 RSA 對象的生命周期相關聯。

以下代碼似乎確實有效，并且我確認它可以與 Service Fabric 一起使用。
private X509Certificate2 buildSelfSignedServerCertificate(string CertificateName,string password,string dns)
{
SubjectAlternativeNameBuilder sanBuilder = new SubjectAlternativeNameBuilder();
sanBuilder.AddIpAddress(IPAddress.Loopback);
sanBuilder.AddIpAddress(IPAddress.IPv6Loopback);
if (!string.IsNullOrEmpty(dns))
{
sanBuilder.AddDnsName(dns);
}
//
// sanBuilder.AddDnsName(Environment.MachineName);
X500DistinguishedName distinguishedName = new X500DistinguishedName($"CN={CertificateName}");
using (RSA rsa = new RSACryptoServiceProvider(2048 * 2, new CspParameters(24, "Microsoft Enhanced RSA and AES Cryptographic Provider", Guid.NewGuid().ToString())))
{
var request = new CertificateRequest(distinguishedName, rsa, HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1);
//request.CertificateExtensions.Add(
// new X509KeyUsageExtension(X509KeyUsageFlags.DataEncipherment | X509KeyUsageFlags.KeyEncipherment | X509KeyUsageFlags.DigitalSignature, false));
//request.CertificateExtensions.Add(
// new X509EnhancedKeyUsageExtension(
// new OidCollection { new Oid("1.3.6.1.5.5.7.3.1"), new Oid("1.3.6.1.5.5.7.3.2") }, false));
request.CertificateExtensions.Add(sanBuilder.Build());
var certificate = request.CreateSelfSigned(new DateTimeOffset(DateTime.UtcNow.AddDays(-1)), new DateTimeOffset(DateTime.UtcNow.AddDays(3650)));
bool isWindows = System.Runtime.InteropServices.RuntimeInformation
.IsOSPlatform(OSPlatform.Windows);
if(isWindows)
certificate.FriendlyName = CertificateName;
return certificate;
// return new X509Certificate2(certificate.Export(X509ContentType.Pfx, password), password, X509KeyStorageFlags.MachineKeySet);
}
}
