Jef*_*tin 37 .net c# cryptography pkcs#12 x509certificate2
我正在尝试X509Certificate2从字节数组中的PKCS#12 blob 构造一个并且得到一个相当令人费解的错误.此代码在具有Windows XP管理员权限的桌面应用程序中运行.
堆栈跟踪如下,但由于_LoadCertFromBlob已标记,我因试图进行故障排除而丢失[MethodImpl(MethodImplOptions.InternalCall)].
System.Security.Cryptography.CryptographicException: The system cannot find the file specified.

编辑: blob是由BouncyCastle为C#生成的真正的PKCS#12,包含RSA私钥和证书(自签名或最近注册CA) - 我要做的是转换私钥和证书从BouncyCastle库到System.Security.Cryptography库,从一个导出到另一个导入.此代码适用于已经尝试过的绝大多数系统; 我从未见过该构造函数抛出的特定错误.这个盒子可能是某种环境怪异.
编辑2:错误发生在不同城市的不同环境中,我无法在本地重现它,所以我可能最终不得不将其粉碎到破损的XP安装.
既然你问过,这里是有问题的片段.该代码采用BouncyCastle表示中的私钥和证书,从个人密钥库中删除相同专有名称的任何先前证书,并通过中间PKCS#12 blob将新私钥和证书导入个人密钥库.
// open the personal keystore
var msMyStore = new X509Store(StoreName.My);
msMyStore.Open(OpenFlags.MaxAllowed);
// remove any certs previously issued for the same DN
var oldCerts =
msMyStore.Certificates.Cast<X509Certificate2>()
.Where(c => X509Name
.GetInstance(Asn1Object.FromByteArray(c.SubjectName.RawData))
.Equivalent(CurrentCertificate.SubjectDN))
.ToArray();
if (oldCerts.Length > 0) msMyStore.RemoveRange(new X509Certificate2Collection(oldCerts));
// build a PKCS#12 blob from the private key and certificate
var pkcs12store = new Pkcs12StoreBuilder().Build();
pkcs12store.SetKeyEntry(_Pkcs12KeyName,
new AsymmetricKeyEntry(KeyPair.Private),
new[] {new X509CertificateEntry(CurrentCertificate)});
var pkcs12data = new MemoryStream();
pkcs12store.Save(pkcs12data, _Pkcs12Password.ToCharArray(), Random);
// and import it. this constructor call blows up
_MyCertificate2 = new X509Certificate2(pkcs12data.ToArray(),
_Pkcs12Password,
X509KeyStorageFlags.Exportable);
msMyStore.Add(_MyCertificate2);
msMyStore.Close();

你有PKCS#12还是只有PFX文件?在微软世界中它是相同的,但其他人认为另一个(参见http://www.drh-consultancy.demon.co.uk/pkcs12faq-old.html#PFX).
您可以尝试以下
X509Certificate2 cert = X509Certificate2(byte[] rawData, "password");
X509Certificate2 cert2 = X509Certificate2(byte[] rawData, "password",
X509KeyStorageFlags.MachineKeySet |
X509KeyStorageFlags.PersistKeySet |
X509KeyStorageFlags.Exportable);

更新:如果您插入代码片段而不仅仅是异常堆栈跟踪,将会很有帮助.
X509KeyStorageFlags你用哪个?您可以使用Process Monitor找出哪个文件找不到X509Certificate2构造函数.例如,在具有该问题的Windows XP上,当前用户没有默认密钥容器.您可以创建它并重试导入.
