The HTTPServer component offers server-side functionality for the HTTP/HTTPS protocols.

Syntax

nsoftware.SecureBlackbox.Httpserver

Remarks

Both plain (HTTP) and secure (HTTPS) connection types are supported.

Follow the below steps to set up and run the server in your code:

  • Create an instance of the server component and set up the license, if assumed by the edition you are using: var server = new Httpserver(); server.RuntimeLicense = "5342..0000";
  • Set up the listening port (make sure it is not in use): server.Port = 443;
  • Tell the component whether TLS connections should be enforced: server.UseTLS = true; // set to false to disable TLS and server plain HTTP requests
  • Set up the document root (a directory where all static files are kept): server.DocumentRoot = "c:\\inetpub\\mywebserver";
  • (TLS-enabled servers only) Configure TLS parameters. The exact way of doing that may vary for different scenarios and security requirements. At the very least you need to set up the certificate chain that the server will use to authenticate itself to connecting clients. If you don"t, the component will generate a dummy certificate itself, however, that certificate is unlikely to pass any security requirements. It will let you accept test connections though.

    Below is an example of tuning up the TLS parameters of the server: // *** Switching TLS on and enabling the implicit mode *** server.UseTLS = true; server.TLSSettings.TLSMode = smImplicitTLS; // this must be implicit for HTTPS // Loading the certificate chain var mgr = new Certificatemanager(); mgr.RuntimeLicense = "5342..0000"; // *** Setting up the host certificate *** // - it should be issued in the name that matches the hostname (such as domain.com) or its IP address (1.2.3.4), // - it must have an associated private key - so likely is provided in PFX or PEM format. mgr.ImportFromFile("CertTLSServer.pfx", "password"); server.ServerCertificates.Add(mgr.Certificate); // The CA certificate: this is to help connecting clients validate the chain. mgr.ImportFromFile("CertCA.cer", ""); server.ServerCertificates.Add(mgr.Certificate); // *** Adjusting finer-grained TLS settings *** // - session resumption (allows for faster handshakes for connections from the same origin) server.TLSSettings.UseSessionResumption = true; // - secure configuration server.TLSSettings.BaseConfiguration = stpcHighlySecure; // - disabling a cipher suite we dislike (just because we can): server.TLSSettings.Ciphersuites = "-DHE_RSA_AES128_SHA" // *** Configuring versions *** // The default version setting at the time of writing (May 2021) is TLS 1.2 and TLS 1.3, // but that may change in future versions. The following tune-up additionally activates TLS 1.1 and TLS 1.0, // which weakens security, but may be necessary to accept connections from older clients: server.TLSSettings.Versions = csbTLS1 | csbTLS11 | csbTLS12 | csbTLS13;

  • Now that your server has been fully set up, activate it: server.Start();
  • Once the Start call completes, your server can accept connections from clients. Each accepted connection runs in a separate thread, not interfering with each other or your own threads. The server communicates its ongoing activities to your application by throwing events. The lower-level events deal with the underlying network connections:
    • Accept notifies you about a new incoming connection. This event lets you accept or reject it.
    • Connect notifies your code of an accepted connection. This event introduces a ConnectionID, a unique identifier that you can use to track the connection throughout its lifetime.
    • Disconnect notifies you that a connection has been closed.
    • TLSEstablished and TLSShutdown let you know that a TLS layer has been activated/deactivated.
    • Error reports a protocol or other error.
    • CertificateValidate communicates the client authentication event to your code. To access the certificate(s) provided by the authenticating client, pin the client and use the PinnedClientChain property to access its chain: server.PinClient(e.ConnectionID); e.Accept = CheckCert(server.PinnedClientChain);
    The higher-level events let you know what is going on at the HTTP layer, and let you serve your content on the fly:
    • GetRequest fires when a GET request is received from a connection.
    • PostRequest notifies your code about a POST request. Similar events for other HTTP request types (e.g. DELETE) are also available.
    • AuthAttempt fires when a connected client tries HTTP authentication (such as basic or digest) and let you accept or reject it.

    Note: every such event is thrown from the respective connection thread, so make sure you use some synchronization mechanism when dispatching the events to your UI thread - for example, by updating UI controls by sending a Window Message rather than accessing the controls directly.

  • Use GetRequestStream, GetRequestString, and GetRequestHeader methods inside your GetRequest and similar event handlers to access request parameters and content supplied by the client. Use SetResponseHeader and SetResponseString method to supply the response content: void serverGetRequest(object sender, EventArgs e) { e.Handled = true; // telling the Httpserver object that we will supply our own content if (e.URI == "/index.html") { server.SetResponseStatus(e.ConnectionID, 200); server.SetResponseString(e.ConnectionID, "<html><head></head><body>Hello!</body></html>", "text/html"); } else if (e.URI == "/secretfile") { server.SetResponseStatus(e.ConnectionID, 200); server.SetResponseBytes(e.ConnectionID, m_secretData, "application/pdf"); } else if (e.URI.StartsWith("/static/")) { e.Handled = false; // letting the server process the content and flush the file from the home directory (c:\inetpub\mywebserver) } else { Flush404Page(e.ConnectionID); } }
  • To stop the server, call Stop: server.Stop();

HTTPServer and SSLLabs

Qualys SSLLabs (https://www.ssllabs.com/) has been long known as a comprehensive TLS site quality checking tool. It is now a de-facto standard and a sign of good taste to aspire for the best SSLLabs test result for your web presence. SecureBlackbox developers share that effort and want to help their customers build secure TLS endpoints that can be independently endorsed by third-party evaluators like SSLLabs.

Having said that, when assessing SecureBlackbox TLS-capable servers that are configured to use their default setup, you will often end up with a lower SSLLabs score than you could have. There is a simple reason for that. Being a vendor of a library used by thousands of customers, we have to find a delicate balance between security, compatibility, and keeping class contracts rolling from one product build to another. This makes the default configuration of the components not the strongest possible. To put it simple, we could easily make the default component setup bulletproof - but having done that, we would have likely ended up with hundreds of customers stuck with legacy environments (and there are a lot of them around) losing their connectivity.

If you are looking at achieving the best score at SSLLabs, please read on. The below guidance aims to help you tune up the server component in the way that should give you an A score.

First, switch your server to the highly secure base configuration: server.TLSSettings.BaseConfiguration = stpcHighlySecure; This should immediately give you an A, or a T if your server certificate does not chain up to a trusted anchor.

Some warnings will still be included in the report. One of those is related to the session resumption. It is normally shown in orange:

Session resumption (caching): No (IDs assigned but not accepted)

This literally means that the server is not configured to re-use older sessions, which may put extra computational burden on clients and itself. Use the following setting to enable session caching: server.TLSSettings.UseSessionResumption = true;

Besides, the report may show that there are some weak ciphersuites. All of those should be shown in orange (there should not be any reds; if there are - please let us know), which means they are only relatively weak. While switching them off may affect the interoperability level of the server, you may still want to do that. By using the below approach you can disable individual ciphersuites selectively. For example, if the report shows that TLS_DHE_RSA_WITH_AES128_CBC_SHA256 and TLS_DHE_RSA_WITH_AES256_CBC_SHA256 are weak (because of their CBC mode), you can disable them in the following way: server.TLSSettings.Ciphersuites = '-DHE_RSA_AES128_SHA256;-DHE_RSA_AES256_SHA256'; Note that SBB uses slightly different, simpler naming convention by dropping unnecessart WITH and CBC. Let us know if you have difficulties matching the cipher suite names.

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the component via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

Public Delegate Sub OnTLSShutdownHandler(sender As Object, e As HttpserverTLSShutdownEventArgs)

Public Class HttpserverTLSShutdownEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionID As Long
End Class

Remarks

The component fires this event when a connected client closes their TLS session gracefully. This event is typically followed by a Disconnect, which marks the closure of the underlying TCP session.

TraceRequest Event (HTTPServer Component)

Reports a TRACE request.

Syntax

public event OnTraceRequestHandler OnTraceRequest;

public delegate void OnTraceRequestHandler(object sender, HttpserverTraceRequestEventArgs e);

public class HttpserverTraceRequestEventArgs : EventArgs {
  public long ConnectionID { get; }
  public string URI { get; }
  public bool Handled { get; set; }
}
Public Event OnTraceRequest As OnTraceRequestHandler

Public Delegate Sub OnTraceRequestHandler(sender As Object, e As HttpserverTraceRequestEventArgs)

Public Class HttpserverTraceRequestEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionID As Long
  Public ReadOnly Property URI As String
  Public Property Handled As Boolean
End Class

Remarks

The component fires this event to notify the application about a TRACE request received from the client.

ConnectionID indicates the connection that sent the request and URI suggests the requested resource.

Set Handled to true to indicate that your application's code will take care of the request. The application does it by providing the necessary details via SetResponseStatus, SetResponseHeader, and SetResponseFile methods. If the returned value of Handled is false, the server will try to take care of the request automatically by searching for the requested resource in DocumentRoot.

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Bytes
byte[] (read-only)

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth component.

If set to true, the component will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

HashAlgorithm
string

Default Value: "SHA256"

Specifies the request's signature hash algorithm.

KeyID
string

Default Value: ""

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

KeySecret
string

Default Value: ""

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the KeyID topic.

Method

PublicKeyAlgorithm
string

Default Value: ""

Provide the public key algorithm here if the certificate is not available on the pre-signing stage.

RenegotiationAttackPreventionModes

Default Value: 0

Selects the renegotiation attack prevention mechanism.

The following options are available:

crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
RevocationCheckKinds

Default Value: 1

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

crcNone0No revocation checking.
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2All provided CRL endpoints will be checked, and all checks must succeed.
crcAllOCSP3All provided OCSP endpoints will be checked, and all checks must succeed.
crcAllCRLAndOCSP4All provided CRL and OCSP endpoints will be checked, and all checks must succeed.
crcAnyCRL5All provided CRL endpoints will be checked, and at least one check must succeed.
crcAnyOCSP6All provided OCSP endpoints will be checked, and at least one check must succeed.
crcAnyCRLOrOCSP7All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

Config Settings (HTTPServer Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

HTTPServer Config Settings

AllowOptionsResponseWithoutAuth:   Enables unauthenticated responses to OPTIONS requests.

Set this property to true to allow the server serve OPTIONS requests without prior authentication of the client.

ClientAuth:   Enables or disables certificate-based client authentication.

Set this property to one of the below values to tune up the client authentication logic:

0No client authentication (the default setting)
1Request certificates. The server will ask connecting clients for their certificates. Non-authenticated client connections will be accepted anyway.
2Require certificates. The server will ask connecting clients for their certificates. If a client fails to provide a certificate, the server will terminate the connection.

If this property is set to 1 or 2, the component will request certificates from the connecting clients. Depending on the setting, the clients that fail to provide their certificate in response will be allowed or disallowed to proceed with the connection. The server signals about a received certificate by firing its CertificateValidate event. Use PinClient method in the event handler to pin the client details, and access the provided certificate chain via the PinnedClientChain property.

Note that this event is fired from the connecting clients threads, so please make sure you avoid bottlenecks in the event handler and put appropriate thread safety measures in place.

Unlike the client-side components, the server component does not perform automated certificate validation against the local security policy. You must perform appropriate certificate validation steps in your CertificateValidate event handler.

DualStack:   Allows the use of ip4 and ip6 simultaneously.

This setting specifies a socket can use ip4 and ip6 simultaneously.

HomePage:   Specifies the home page resource name.

Use this property to specify the home page (/) resource name.

Host:   The host to bind to.

Specifies a specific interface the server should listen on.

RequestFilter:   The request string modifier.

Use this property to tune up the request string as returned by GetRequestString method. Supported filters: params (request parameters only), params[Index] or params['Name'] (a specific request parameter), parts[Index] (the contents of a particular part of a multipart message). An empty request filter makes GetRequestString return the whole body of the request.

ServerSSLDHKeyLength:   Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

WebsiteName:   The website name for the TLS certificate.

Assign this property with a name to put in a self-generated TLS certificate.

Base Config Settings

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the component.

Supported values are:

offNo caching (default)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the component.

Use this property to get cookies from the internal cookie storage of the component and/or restore them back between application sessions.

DefDeriveKeyIterations:   Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the components that have its CookieCaching property set to "global".

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other components.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile
consoleConsole

exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

LogRotationMode:   Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the component) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the components.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemOAEPAndPSS:   Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom:   Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.
