C＃非自簽署的CertEnroll.dll客戶端證書無法被驗證

這是一個後續到C# Generate a non self signed client CX509Certificate Request without a CA using the certenroll.dll C＃非自簽署的CertEnroll.dll客戶端證書無法被驗證

我想創建我的自簽署客戶端證書籤名的CA，如上面的問題。我可以使用makecert.exe（它們顯示爲可信）來創建所需的證書而不會造成問題。我試圖在C#中做同樣的事情。證書被創建並放入機器的My商店中。自簽名的CA也安裝在機器的Trusted商店中。當我打開它們時，他們會說：

Windows沒有足夠的信息來驗證此證書。

幫助？

代碼：

// create DN 
var dn = new CX500DistinguishedName(); 
dn.Encode("CN=Demo Cert", X500NameFlags.XCN_CERT_NAME_STR_NONE); 

// create prvate key 
var pk = new CX509PrivateKey(); 
pk.MachineContext = true; 
pk.Length = 1024; 
pk.KeySpec = X509KeySpec.XCN_AT_KEYEXCHANGE; 
pk.ExportPolicy = X509PrivateKeyExportFlags.XCN_NCRYPT_ALLOW_EXPORT_FLAG; 
pk.Create(); 

// use SHA512 
var hash = new CObjectId(); 
hash.InitializeFromAlgorithmName(ObjectIdGroupId.XCN_CRYPT_HASH_ALG_OID_GROUP_ID, ObjectIdPublicKeyFlags.XCN_CRYPT_OID_INFO_PUBKEY_ANY, AlgorithmFlags.AlgorithmFlagsNone, "SHA512"); 

// EKU 
var oid = new CObjectId(); 
oid.InitializeFromValue("1.3.6.1.5.5.7.3.2"); 
var oidlist = new CObjectIds(); 
oidlist.Add(oid); 
var eku = new CX509ExtensionEnhancedKeyUsage(); 
eku.InitializeEncode(oidlist); 

// Initialize the signer 
var TheCA = GimmeTheCA(); // method returns my self signed CA as X509Certificate2 
ISignerCertificate signer = new CSignerCertificate(); 
signer.Initialize(true, X509PrivateKeyVerify.VerifyNone, EncodingType.XCN_CRYPT_STRING_HEX, TheCA.GetRawCertDataString()); 

// Root Dn 
var Rootdn = new CX500DistinguishedName(); 
Rootdn.Encode(TheCA.Subject, X500NameFlags.XCN_CERT_NAME_STR_NONE); 

// Cert Request 
var cert = new CX509CertificateRequestCertificate(); 
cert.InitializeFromPrivateKey(X509CertificateEnrollmentContext.ContextMachine, pk, ""); 
cert.Subject = dn; 
cert.Issuer = Rootdn; 
cert.SignerCertificate = (CSignerCertificate)signer; 
cert.NotBefore = DateTime.Now; 
cert.NotAfter = new DateTime(2020, 1, 1); 
cert.X509Extensions.Add((CX509Extension)eku); 
cert.HashAlgorithm = hash; 
cert.Encode(); 

// Enrollment 
var enroll = new CX509Enrollment(); 
enroll.InitializeFromRequest(cert); 
enroll.CertificateFriendlyName = "Intel IPT"; 
string csr = enroll.CreateRequest(); 

// Install 
enroll.InstallResponse(InstallResponseRestrictionFlags.AllowUntrustedRoot, csr, EncodingType.XCN_CRYPT_STRING_BASE64, "");

您是否曾經找到過解決方案？ – an0nym0usc0ward

不是，我使用了MS獨立CA的證書，而不是自簽名證書。 –

你可以試試：

pk.KeySpec = X509KeySpec.XCN_AT_SIGNATURE;
pk.KeyUsage = X509PrivateKeyUsageFlags.XCN_NCRYPT_ALLOW_ALL_USAGES;
使用提升權限運行應用程序（以管理員身份運行）。在「Computer \ Personal」（「MY」）商店中放置CA證書的副本（但將原始證書保存在「Computer \ Trusted Root Cert。Auth。」（「Root」）商店中）
