The DCAuthWebServer Class offers higher-level access to 'private key side' functionality of SecureBlackbox DC protocol.

Syntax

class secureblackbox.DCAuthWebServer

Remarks

DCAuthWebServer provides a built-in REST responder for DC requests. Use it in conjunction with the in-browser Javascript that comes with DC package, or with standalone DC requestors. DCAuthWebServer listens to DC requests on a specific port or a port chosen between port_range_from and port_range_to. Use DCAuth, which provides a lower-level access to the signing engine, to implement DC in applications, apps, or services.

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 external_crypto_key_secret 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";

You can use the following URI modifiers to provide more accurate specifiers for the needed certificate:

• cn: the common name of the certificate subject.
• keyid: the unique identifier included in subject key identifier extension of the certificate.

timestamp_server Property

The address of the timestamping server.

Syntax

def get_timestamp_server() -> str: ...
def set_timestamp_server(value: str) -> None: ...

timestamp_server = property(get_timestamp_server, set_timestamp_server)

Default Value

""

Remarks

Use this property to provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature.

SecureBlackbox supports RFC3161-compliant timestamping servers, available via HTTP or HTTPS.

If your timestamping service enforces credential-based user authentication (basic or digest), you can provide the credentials in the same URL:

http://user:password@timestamp.server.com/TsaService

For TSAs using certificate-based TLS authentication, provide the client certificate via the tls_client_chain property.

If this property is left empty, no timestamp will be added to the signature.

Starting from summer 2021 update (Vol. 2), the virtual timestamping service is supported, which allows you to intervene in the timestamping routine and provide your own handling for the TSA exchange. This may be handy if the service that you are requesting timestamps from uses a non-standard TSP protocol or requires special authentication option.

To employ the virtual service, assign an URI of the following format to this property:

virtual://localhost?hashonly=true&includecerts=true&reqpolicy=1.2.3.4.5&halg=SHA256

Subscribe to on_notification event to get notified about the virtualized timestamping event. The EventID of the timestamping event is TimestampRequest. Inside the event handler, read the base16-encoded request from the EventParam parameter and forward it to the timestamping authority. Upon receiving the response, pass it back to the component, encoded in base16, via the TimestampResponse config property:

component.Config("TimestampResponse=308208ab...");

Note that all the exchange with your custom TSA should take place within the same invocation of the Notification event.

The hashonly parameter of the virtual URI tells the component to only return the timestamp message imprint via the EventParam parameter. If set to false, EventParam will contain the complete RFC3161 timestamping request.

The includecerts parameter specifies that the requestCertificates parameter of the timestamping request should be set to true.

The reqpolicy parameter lets you specify the request policy, and the halg parameter specifies the hash algorithm to use for timestamping.

All the parameters are optional.

tls_auto_validate_certificates Property

Syntax

def get_tls_auto_validate_certificates() -> bool: ...
def set_tls_auto_validate_certificates(value: bool) -> None: ...

Syntax

def get_tls_base_configuration() -> int: ...
def set_tls_base_configuration(value: int) -> None: ...

tls_base_configuration = property(get_tls_base_configuration, set_tls_base_configuration)

Syntax

def get_tls_ciphersuites() -> str: ...
def set_tls_ciphersuites(value: str) -> None: ...

tls_ciphersuites = property(get_tls_ciphersuites, set_tls_ciphersuites)

Default Value

""

Remarks

A list of ciphersuites separated with commas or semicolons. Each ciphersuite in the list may be prefixed with a minus sign (-) to indicate that the ciphersuite should be disabled rather than enabled. Besides the specific ciphersuite modifiers, this property supports the all (and -all) aliases, allowing all ciphersuites to be blanketly enabled or disabled at once.

Note: the list of ciphersuites provided to this property alters the baseline list of ciphersuites as defined by tls_base_configuration. Remember to start your ciphersuite string with -all; if you need to only enable a specific fixed set of ciphersuites. The list of supported ciphersuites is provided below:

def get_tls_revocation_check() -> int: ...
def set_tls_revocation_check(value: int) -> None: ...

tls_revocation_check = property(get_tls_revocation_check, set_tls_revocation_check)

Default Value

1

Remarks

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.

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.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

do_action Method

Performs an additional action.

Syntax

def do_action(action_id: str, action_params: str) -> str: ...

Remarks

do_action is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

Syntax

class DCAuthWebServerExternalSignEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def operation_id() -> str: ...

  @property
  def hash_algorithm() -> str: ...

  @property
  def pars() -> str: ...

  @property
  def data() -> str: ...

  @property
  def signed_data() -> str: ...
  @signed_data.setter
  def signed_data(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_external_sign() -> Callable[[DCAuthWebServerExternalSignEventParams], None]: ...
@on_external_sign.setter
def on_external_sign(event_hook: Callable[[DCAuthWebServerExternalSignEventParams], None]) -> None: ...

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 class via the SignedData parameter.

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

The class 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(); };

on_key_secret_needed Event

Requests the key secret from the application.

Syntax

class DCAuthWebServerKeySecretNeededEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def key_id() -> str: ...

  @property
  def key_secret() -> str: ...
  @key_secret.setter
  def key_secret(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_key_secret_needed() -> Callable[[DCAuthWebServerKeySecretNeededEventParams], None]: ...
@on_key_secret_needed.setter
def on_key_secret_needed(event_hook: Callable[[DCAuthWebServerKeySecretNeededEventParams], None]) -> None: ...

Remarks

Subscribe to this event to pass the key secret (a pre-shared request authentication code) to the signing component when it is needed. The authentication combination consists of the KeyId, a non-secret unique key identifier, and the KeySecret, shared by the parties, which should be kept private. This event is an alternative for key_secret property. Use it when you expect to process requests from requestors with different KeyIds and secrets. If you only expect to receive requests from a single requestor with a known KeyId, providing the key secret via key_id and key_secret properties would be an easier route.

on_log Event

Reports a single log line.

Syntax

class DCAuthWebServerLogEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def log_type() -> int: ...

  @property
  def details() -> str: ...

# In class DCAuthWebServer:
@property
def on_log() -> Callable[[DCAuthWebServerLogEventParams], None]: ...
@on_log.setter
def on_log(event_hook: Callable[[DCAuthWebServerLogEventParams], None]) -> None: ...

Remarks

This event is fired repeatedly during the component's work to inform the application about the flow of the signing process. The application may use this event to create an operation log.

# In class DCAuthWebServer:
@property
def on_notification() -> Callable[[DCAuthWebServerNotificationEventParams], None]: ...
@on_notification.setter
def on_notification(event_hook: Callable[[DCAuthWebServerNotificationEventParams], None]) -> None: ...

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

on_parameter_received Event

Passes a standard request parameter to the user code.

Syntax

class DCAuthWebServerParameterReceivedEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def name() -> str: ...

  @property
  def value() -> str: ...

# In class DCAuthWebServer:
@property
def on_parameter_received() -> Callable[[DCAuthWebServerParameterReceivedEventParams], None]: ...
@on_parameter_received.setter
def on_parameter_received(event_hook: Callable[[DCAuthWebServerParameterReceivedEventParams], None]) -> None: ...

Remarks

This event is fired when one of 'standard' protocol parameters has been found in the request:

• SessionID
• DataURL
• GoURL
• Token
• PKCS11Libraries
• AllowFileStorage
• AllowTokenStorage
• AllowWindowsStorage
• AllowOSStorage

Parameters are reported one-by-one upon being processed.

on_password_needed Event

Requests a password from the application.

Syntax

class DCAuthWebServerPasswordNeededEventParams(object):
  @property
  def needed_for() -> str: ...

  @property
  def id() -> str: ...

  @property
  def password() -> str: ...
  @password.setter
  def password(value) -> None: ...

  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_password_needed() -> Callable[[DCAuthWebServerPasswordNeededEventParams], None]: ...
@on_password_needed.setter
def on_password_needed(event_hook: Callable[[DCAuthWebServerPasswordNeededEventParams], None]) -> None: ...

Remarks

Subscribe to this event to pass a password to the server component. The NeededFor parameter specifies the entity a password for which is being requested (which is typically a certificate). The Id parameter provides the entity's identifier, such as a path to the certificate being loaded. When handling this event, assign the Password to the valid password if you have it; otherwise, set Cancel to true to abort the operation.

on_read_option Event

Fires when the client sends in a read option request.

Syntax

class DCAuthWebServerReadOptionEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def name() -> str: ...

  @property
  def value() -> str: ...
  @value.setter
  def value(value) -> None: ...

@on_read_option.setter
def on_read_option(event_hook: Callable[[DCAuthWebServerReadOptionEventParams], None]) -> None: ...

Remarks

Subscribe to this event to respond to the clients' read option requests. The handler should retrieve the value of the requested option from a local configuration setting and assign it to the Value parameter.

on_select_cert Event

Requests certificate selection criteria from the application.

Syntax

class DCAuthWebServerSelectCertEventParams(object):
  @property
  def connection_id() -> int: ...

  @property

def on_select_cert() -> Callable[[DCAuthWebServerSelectCertEventParams], None]: ...
@on_select_cert.setter
def on_select_cert(event_hook: Callable[[DCAuthWebServerSelectCertEventParams], None]) -> None: ...

Remarks

Subscribe to this event to provide signing certificate details on the fly, right before the hash is signed.

on_sign_request Event

This event signifies the processing of an atomic signing request.

Syntax

class DCAuthWebServerSignRequestEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def method() -> int: ...

  @property
  def hash_algorithm() -> str: ...

  @property
  def hash() -> bytes: ...

  @property
  def key_id() -> str: ...

  @property
  def pars() -> str: ...

  @property
  def method_pars() -> str: ...

  @property
  def allow() -> bool: ...
  @allow.setter
  def allow(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_sign_request() -> Callable[[DCAuthWebServerSignRequestEventParams], None]: ...
@on_sign_request.setter
def on_sign_request(event_hook: Callable[[DCAuthWebServerSignRequestEventParams], None]) -> None: ...

Remarks

Subscribe to this event to be notified of every signature request processed by the DC server. Note that any one request coming from the requestor may contain multiple individual signature requests (so-called 'batching'). This event is a good mechanism to track signature requests for accountability purposes, and provide basic access control over the signing operations. The Method parameter specifies the async signing method requested by the client:

The Hash parameter contains the hash, made using HashAlgorithm, that needs to be signed. KeyID contains the key identifier of the requestor.

The Pars string contains a semicolon-separated string of the principal signature parameters. This has the same format and content that is passed to on_external_sign, if it is used. The MethodPars contains a similar parameter string, but for the specific async signing method used. For the PKCS1 method there are no defined method parameters, while the PKCS7 method supports a selection of settings that tune up the CMS blob.

Set Allow to false to reject the request. Use the on_sign_request_completed event to track completion of the initiated operation.

on_sign_request_completed Event

This event signifies completion of the processing of an atomic signing request.

Syntax

class DCAuthWebServerSignRequestCompletedEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def method() -> int: ...

  @property
  def hash_algorithm() -> str: ...

  @property
  def hash() -> bytes: ...

  @property
  def key_id() -> str: ...

  @property
  def pars() -> str: ...

  @property
  def method_pars() -> str: ...

  @property
  def signature() -> bytes: ...

# In class DCAuthWebServer:
@property
def on_sign_request_completed() -> Callable[[DCAuthWebServerSignRequestCompletedEventParams], None]: ...
@on_sign_request_completed.setter
def on_sign_request_completed(event_hook: Callable[[DCAuthWebServerSignRequestCompletedEventParams], None]) -> None: ...

Remarks

Use this event to track completion of signing request processing. The Hash parameter contains the hash that is signed, as supplied by the requestor, and the Signature parameter contains the resulting cryptographic signature. The Username parameter matches the parameter in on_sign_request event.

on_timestamp_request Event

Fires when the class is ready to request a timestamp from an external TSA.

Syntax

class DCAuthWebServerTimestampRequestEventParams(object):
  @property
  def tsa() -> str: ...

  @property
  def timestamp_request() -> str: ...

  @property
  def timestamp_response() -> str: ...
  @timestamp_response.setter
  def timestamp_response(value) -> None: ...

  @property
  def suppress_default() -> bool: ...
  @suppress_default.setter
  def suppress_default(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_timestamp_request() -> Callable[[DCAuthWebServerTimestampRequestEventParams], None]: ...
@on_timestamp_request.setter
def on_timestamp_request(event_hook: Callable[[DCAuthWebServerTimestampRequestEventParams], None]) -> None: ...

Remarks

Subscribe to this event to intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.

The TSA parameter indicates the timestamping service being used. It matches the value passed to the timestamp_server property. Set the SuppressDefault parameter to false if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned TimestampResponse parameter is not empty.

on_tls_cert_validate Event

Fires when a client certificate needs to be validated.

Syntax

class DCAuthWebServerTLSCertValidateEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_tls_cert_validate() -> Callable[[DCAuthWebServerTLSCertValidateEventParams], None]: ...
@on_tls_cert_validate.setter
def on_tls_cert_validate(event_hook: Callable[[DCAuthWebServerTLSCertValidateEventParams], None]) -> None: ...

Remarks

The class fires this event to notify the application of an authenticating client. Use the event handler to validate the certificate and pass your decision back to the server component via the Accept parameter.

on_tls_established Event

Reports the setup of a TLS session.

Syntax

class DCAuthWebServerTLSEstablishedEventParams(object):
  @property
  def connection_id() -> int: ...

# In class DCAuthWebServer:
@property
def on_tls_established() -> Callable[[DCAuthWebServerTLSEstablishedEventParams], None]: ...
@on_tls_established.setter
def on_tls_established(event_hook: Callable[[DCAuthWebServerTLSEstablishedEventParams], None]) -> None: ...

Remarks

Subscribe to this event to be notified about the setup of a TLS connection by a connected client.

on_tls_handshake Event

Fires when a newly established client connection initiates a TLS handshake.

Syntax

class DCAuthWebServerTLSHandshakeEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def server_name() -> str: ...

  @property
  def abort() -> bool: ...
  @abort.setter
  def abort(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_tls_handshake() -> Callable[[DCAuthWebServerTLSHandshakeEventParams], None]: ...
@on_tls_handshake.setter
def on_tls_handshake(event_hook: Callable[[DCAuthWebServerTLSHandshakeEventParams], None]) -> None: ...

Remarks

Use this event to get notified about the initiation of the TLS handshake by the remote client. The ServerName parameter specifies the requested host from the client hello message.

on_tls_psk Event

Requests a pre-shared key for TLS-PSK.

Syntax

class DCAuthWebServerTLSPSKEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def identity() -> str: ...

  @property
  def psk() -> str: ...
  @psk.setter
  def psk(value) -> None: ...

  @property
  def ciphersuite() -> str: ...
  @ciphersuite.setter
  def ciphersuite(value) -> None: ...

# In class DCAuthWebServer:
@property
def on_tls_psk() -> Callable[[DCAuthWebServerTLSPSKEventParams], None]: ...
@on_tls_psk.setter
def on_tls_psk(event_hook: Callable[[DCAuthWebServerTLSPSKEventParams], None]) -> None: ...

Remarks

The class fires this event to report that a client has requested a TLS-PSK negotiation. ConnectionId indicates the unique connection ID that requested the PSK handshake.

Use Identity to look up for the corresponding pre-shared key in the server's database, then assign the key to the PSK parameter. If TLS 1.3 PSK is used, you will also need to assign the Ciphersuite parameter with the cipher suite associated with that identity and their key.

on_tls_shutdown Event

Reports closure of a TLS session.

Syntax

class DCAuthWebServerTLSShutdownEventParams(object):
  @property
  def connection_id() -> int: ...

# In class DCAuthWebServer:
@property
def on_tls_shutdown() -> Callable[[DCAuthWebServerTLSShutdownEventParams], None]: ...
@on_tls_shutdown.setter
def on_tls_shutdown(event_hook: Callable[[DCAuthWebServerTLSShutdownEventParams], None]) -> None: ...

Remarks

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

on_write_option Event

Fires when the client sends in a write option request.

Syntax

class DCAuthWebServerWriteOptionEventParams(object):
  @property
  def connection_id() -> int: ...

  @property
  def name() -> str: ...

  @property
  def value() -> str: ...

# In class DCAuthWebServer:
@property
def on_write_option() -> Callable[[DCAuthWebServerWriteOptionEventParams], None]: ...
@on_write_option.setter
def on_write_option(event_hook: Callable[[DCAuthWebServerWriteOptionEventParams], None]) -> None: ...

Remarks

Subscribe to this event to respond to the clients' write option requests. The handler should save the Value of the Name option to a local configuration database.

DCAuthWebServer Config Settings

The class 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 class, access to these internal properties is provided through the config method.
