我有一个自托管的WCF服务器作为本地系统帐户下的Windows服务运行.我正在尝试以编程方式在c#中创建自签名证书,以便使用消息级别安全性与net.tcp端点一起使用.

我使用以下代码,它非常基于如何使用C#创建自签名证书中的接受答案？试图解决我的问题的一些小变化.

public static X509Certificate2 CreateSelfSignedCertificate(string subjectName, TimeSpan expirationLength)
{
    // create DN for subject and issuer
    var dn = new CX500DistinguishedName();
    dn.Encode("CN=" + subjectName, X500NameFlags.XCN_CERT_NAME_STR_NONE);

    CX509PrivateKey privateKey = new CX509PrivateKey();
    privateKey.ProviderName = "Microsoft Strong Cryptographic Provider";
    privateKey.Length = 1024;
    privateKey.KeySpec = X509KeySpec.XCN_AT_KEYEXCHANGE;
    privateKey.KeyUsage = X509PrivateKeyUsageFlags.XCN_NCRYPT_ALLOW_DECRYPT_FLAG | X509PrivateKeyUsageFlags.XCN_NCRYPT_ALLOW_KEY_AGREEMENT_FLAG;
    privateKey.MachineContext = true;
    privateKey.ExportPolicy = X509PrivateKeyExportFlags.XCN_NCRYPT_ALLOW_EXPORT_FLAG;
    privateKey.Create();

    // Use the stronger SHA512 hashing algorithm
    var hashobj = new CObjectId();
    hashobj.InitializeFromAlgorithmName(ObjectIdGroupId.XCN_CRYPT_HASH_ALG_OID_GROUP_ID,
        ObjectIdPublicKeyFlags.XCN_CRYPT_OID_INFO_PUBKEY_ANY,
        AlgorithmFlags.AlgorithmFlagsNone, "SHA1");

    // Create the self signing …
