public bool IgnoreChainValidationErrors { get; set; }
Public Property IgnoreChainValidationErrors As Boolean
Default Value
False
Remarks
If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.

Contains the validation status of the moment.
Syntax
public AuthenticodesignerInterimValidationResults InterimValidationResult { get; set; }
enum AuthenticodesignerInterimValidationResults { cvtValid, cvtValidButUntrusted, cvtInvalid, cvtCantBeEstablished }
Public Property InterimValidationResult As AuthenticodesignerInterimValidationResults
Enum AuthenticodesignerInterimValidationResults cvtValid cvtValidButUntrusted cvtInvalid cvtCantBeEstablished End Enum
Default Value
0
Remarks
Over the course of the validation process, the validator maintains an interim validity status for the chain that is being processed. This status is influenced by every single step of the validation routine, and may change along the way, before the end of the chain is reached and the final validation conclusion is drawn.
Use this property to check the interim validity status mid-flight.
| cvtValid | 0 | The chain is valid |
| cvtValidButUntrusted | 1 | The chain is valid, but the root certificate is not trusted |
| cvtInvalid | 2 | The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature) |
| cvtCantBeEstablished | 3 | The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses) |
This property is not available at design time.
KnownCertificates Property (AuthenticodeSigner Component)
Additional certificates for chain validation.
Syntax
public CertificateList KnownCertificates { get; }
Public Property KnownCertificates As CertificateList
Remarks
Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of certificates to be added to this collection is roughly equivalent to that of Intermediate Certification Authorities system store in Windows.
Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.
This property is not available at design time.
KnownCRLs Property (AuthenticodeSigner Component)
Additional CRLs for chain validation.
Syntax
Remarks
Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.
This property is not available at design time.
KnownOCSPs Property (AuthenticodeSigner Component)
Additional OCSP responses for chain validation.
Syntax
public OCSPResponseList KnownOCSPs { get; }
Public Property KnownOCSPs As OCSPResponseList
Remarks
Use this property to supply additional OCSP responses that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated OCSP responses are stored separately from the signed message or document.
This property is not available at design time.
OfflineMode Property (AuthenticodeSigner Component)
Switches the component to the offline mode.
Syntax
Default Value
False
Remarks
When working in offline mode, the component restricts itself from using any online revocation information sources, such as CRL or OCSP responders.
Offline mode may be useful if there is a need to verify the completeness of validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.
OutputBytes Property (AuthenticodeSigner Component)
Use this property to read the output the component object has produced.
Syntax
Remarks
Read the contents of this property after the operation is completed to read the produced output. This property will only be set if OutputFile and OutputStream properties had not been assigned.
This property is read-only and not available at design time.
OutputFile Property (AuthenticodeSigner Component)
The file to save the signed executable to.
Syntax
Default Value
""
Remarks
A path to the file where the component should save the signed executable file. Use OutputStream to save the signed file to a stream instead.
OutputStream Property (AuthenticodeSigner Component)
The stream where the signed executable should be written to.
Syntax
public System.IO.Stream OutputStream { get; set; }
Public Property OutputStream As System.IO.Stream
Default Value
null
Remarks
Use this property to specify the stream to accommodate the resulting signed executable.
This property is not available at design time.
Profile Property (AuthenticodeSigner Component)
Specifies a pre-defined profile to apply when creating the signature.
Syntax
Default Value
""
Remarks
Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.
Proxy Property (AuthenticodeSigner Component)
The proxy server settings.
Syntax
public ProxySettings Proxy { get; }
Public ReadOnly Property Proxy As ProxySettings
Remarks
Use this property to tune up the proxy server settings.

Specifies whether to remove any existing signatures before signing
Syntax
public bool RemoveExistingSignatures { get; set; }
Public Property RemoveExistingSignatures As Boolean
Default Value
False
Remarks
If this property is set to True, all the existing Authenticode signatures will be removed from the executable before adding the new one. If this property is False, the new signature will be added on top of the existing ones.
RevocationCheck Property (AuthenticodeSigner Component)
Specifies the kind(s) of revocation check to perform.
Syntax
public AuthenticodesignerRevocationChecks RevocationCheck { get; set; }
enum AuthenticodesignerRevocationChecks { crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL }
Public Property RevocationCheck As AuthenticodesignerRevocationChecks
Enum AuthenticodesignerRevocationChecks crcNone crcAuto crcAllCRL crcAllOCSP crcAllCRLAndOCSP crcAnyCRL crcAnyOCSP crcAnyCRLOrOCSP crcAnyOCSPOrCRL End Enum
Default Value
1
Remarks
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
Certificate Revocation Lists (CRL) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.
| crcNone (0) | No revocation checking |
| crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
| crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
| crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
| crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
| crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
| crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL (8) | At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.
SignatureDescription Property (AuthenticodeSigner Component)
Sets human-readable signature description.
Syntax
Default Value
""
Remarks

Syntax
public Certificate SigningCertificate { get; set; }
Public Property SigningCertificate As Certificate
Remarks
Use this property to specify the certificate that shall be used for signing the data. Note that this certificate should have a private key associated with it. Use SigningChain to supply the rest of the certificate chain for inclusion into the signature.
This property is not available at design time.
SigningChain Property (AuthenticodeSigner Component)
The signing certificate chain.
Syntax
public CertificateList SigningChain { get; }
Public Property SigningChain As CertificateList
Remarks
Use this property to provide the chain for the signing certificate. Use SigningCertificate property, if it is available, to provide the signing certificate itself.
This property is not available at design time.
SocketSettings Property (AuthenticodeSigner Component)
Manages network connection settings.
Syntax
public SocketSettings SocketSettings { get; }
Public ReadOnly Property SocketSettings As SocketSettings
Remarks
Use this property to tune up network connection parameters.
This property is read-only.
StatementType Property (AuthenticodeSigner Component)
Sets the signature statement type.
Syntax
public AuthenticodesignerStatementTypes StatementType { get; set; }
enum AuthenticodesignerStatementTypes { acsUnknown, acsIndividual, acsCommercial }
Public Property StatementType As AuthenticodesignerStatementTypes
Enum AuthenticodesignerStatementTypes acsUnknown acsIndividual acsCommercial End Enum
Default Value
1
Remarks
Use this property to specify the signature statement type.
| acsUnknown | 0 |
| acsIndividual | 1 |
| acsCommercial | 2 |
TimestampServer Property (AuthenticodeSigner Component)
The address of the timestamping server.
Syntax
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 TLSClientChain 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 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.
TimestampType Property (AuthenticodeSigner Component)
Sets the signature timestamp type.
Syntax
public AuthenticodesignerTimestampTypes TimestampType { get; set; }
enum AuthenticodesignerTimestampTypes { actUnknown, actLegacy, actTrusted }
Public Property TimestampType As AuthenticodesignerTimestampTypes
Enum AuthenticodesignerTimestampTypes actUnknown actLegacy actTrusted End Enum
Default Value
2
Remarks
Use this property to specify the signature timestamp type. This can either be a "trusted" timestamp (a weird name applied by the Authenticode specification to a standard RFC 3161 timestamp), or a "legacy" timestamp (an older variant of the base64-encoded TSP protocol).
| actUnknown | 0 |
| actLegacy | 1 |
| actTrusted | 2 |
TLSClientChain Property (AuthenticodeSigner Component)
The TLS client certificate chain.
Syntax
public CertificateList TLSClientChain { get; }
Public Property TLSClientChain As CertificateList
Remarks
Assign a certificate chain to this property to enable TLS client authentication in the component. Note that the client's end-entity certificate should have a private key associated with it.
This property is not available at design time.
TLSServerChain Property (AuthenticodeSigner Component)
The TLS server's certificate chain.
Syntax
public CertificateList TLSServerChain { get; }
Public ReadOnly Property TLSServerChain As CertificateList
Remarks
Use this property to access the certificate chain sent by the TLS server.
This property is read-only and not available at design time.
TLSSettings Property (AuthenticodeSigner Component)
Manages TLS layer settings.
Syntax
public TLSSettings TLSSettings { get; }
Public ReadOnly Property TLSSettings As TLSSettings
Remarks
Use this property to tune up the TLS layer parameters.
This property is read-only.
TrustedCertificates Property (AuthenticodeSigner Component)
A list of trusted certificates for chain validation.
Syntax
public CertificateList TrustedCertificates { get; }
Public Property TrustedCertificates As CertificateList
Remarks
Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of this certificate collection is largely the same than that of Windows Trusted Root Certification Authorities system store.
Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.
This property is not available at design time.
ValidationLog Property (AuthenticodeSigner Component)
Contains the complete log of the certificate validation routine.
Syntax
Default Value
""
Remarks
Use this property to access the chain validation log produced by the component. The log can be very useful when investigating issues with chain validation, as it contains a step-by-step trace of the entire validation procedure.
This property is read-only and not available at design time.
Config Method (AuthenticodeSigner Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These 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.
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.
DoAction Method (AuthenticodeSigner Component)
Performs an additional action.
Syntax
Remarks
DoAction is a generic method available in every component. 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.
The unique identifier of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....
ExtractAsyncData Method (AuthenticodeSigner Component)
Extracts user data from the DC signing service response.
Syntax
Remarks
Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.
The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to completion async stage.
Sign Method (AuthenticodeSigner Component)
Calculates and adds a signature to the executable.
Syntax
public void Sign();
Public Sub Sign()
Remarks
Use this method to create a new Authenticode signature over the executable as per the configuration of the component.
SignAsyncBegin Method (AuthenticodeSigner Component)
Initiates the asynchronous signing operation.
Syntax
Remarks
When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in OutputFile (or OutputStream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.
Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to InputFile (or InputStream), and call SignAsyncEnd to finalize the signing.
Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.
AsyncState is a message of the distributed cryptography (DC) protocol. DC protocol is based on exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.
In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.
SignAsyncEnd Method (AuthenticodeSigner Component)
Completes the asynchronous signing operation.
Syntax
Remarks
When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.
Before calling this method, assign the path to the pre-signed copy of the document obtained from prior SignAsyncBegin call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (or OutputStream).
Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

SignExternal Method (AuthenticodeSigner Component)
Signs the document using an external signing facility.
Syntax
public void SignExternal();
Public Sub SignExternal()
Remarks
Use this method to create an Authenticode signature using an external signing facility for the cryptographic computations. SignExternal delegates the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.
When all preparations are done and hash is computed, the component fires ExternalSign event which allows to pass the hash value for signing.
Timestamp Method (AuthenticodeSigner Component)
Use this method to add a timestamp to a new or to an existing signature.
Syntax
public void Timestamp();
Public Sub Timestamp()
Remarks
Call this method to timestamp the signature(s). If only one of the existing signatures should be timestamped, specify its index using the SignatureIndex property.
Use the TimestampServer property to provide the address of the TSA (Time Stamping Authority) server which should be used for timestamping. Use the TimestampType property to specify the type of timestamp to create.
If a timestamp already exists, this will be handled according to the value of the TimestampConflictResolution config property.
Update Method (AuthenticodeSigner Component)
Update an existing signature (or all the signatures) by adding or removing its (their) custom unsigned attributes.
Syntax
public void Update();
Public Sub Update()
Remarks
Call this method to add one or mode custom unsigned attributes to an existing signature (specify its index using the SignatureIndex property) or to all the existing signatures (set SignatureIndex to -1).
Use the CustomUnsignedAttributes property to provide new attributes to be added. If an unsigned attribute with the same OID already exists, this will be handled according to the value of the AttributeConflictResolution config property.
If the CustomUnsignedAttributes property is empty, all the existing unsigned attributes in the specified signature (or all the signatures) will be removed.
ChainElementDownload Event (AuthenticodeSigner Component)
TBD
Syntax
public event OnChainElementDownloadHandler OnChainElementDownload; public delegate void OnChainElementDownloadHandler(object sender, AuthenticodesignerChainElementDownloadEventArgs e); public class AuthenticodesignerChainElementDownloadEventArgs : EventArgs { public string Cert { get; } public string CACert { get; } public string Location { get; } }

ExternalSign Event (AuthenticodeSigner Component)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax
public event OnExternalSignHandler OnExternalSign; public delegate void OnExternalSignHandler(object sender, AuthenticodesignerExternalSignEventArgs e); public class AuthenticodesignerExternalSignEventArgs : EventArgs { public string OperationId { get; } public string HashAlgorithm { get; } public string Pars { get; } public string Data { get; } public string SignedData { get; set; } }
Public Event OnExternalSign As OnExternalSignHandler Public Delegate Sub OnExternalSignHandler(sender As Object, e As AuthenticodesignerExternalSignEventArgs) Public Class AuthenticodesignerExternalSignEventArgs Inherits EventArgs Public ReadOnly Property OperationId As String Public ReadOnly Property HashAlgorithm As String Public ReadOnly Property Pars As String Public ReadOnly Property Data As String Public Property SignedData As String End Class
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 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 contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for 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 a .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();
};
Notification Event (AuthenticodeSigner Component)

Public Event OnNotification As OnNotificationHandler Public Delegate Sub OnNotificationHandler(sender As Object, e As AuthenticodesignerNotificationEventArgs) Public Class AuthenticodesignerNotificationEventArgs Inherits EventArgs Public ReadOnly Property EventID As String Public ReadOnly Property EventParam As String End Class
Remarks
The component fires this event to let the application know about some event, occurrence, or milestone in the component. 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 EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.
This component can fire this event with the following EventID values:
| TimestampRequest | A timestamp is requested from the custom timestamping
authority. This event is only fired if TimestampServer was set to a
virtual:// URI. The EventParam parameter contains the
TSP request (or the plain hash, depending on the value provided to
TimestampServer), in base16, that needs to be sent to the TSA.
Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property. |
Start Event (AuthenticodeSigner Component)
This event is fired when the component is about to start the signing process.
Syntax
public event OnStartHandler OnStart; public delegate void OnStartHandler(object sender, AuthenticodesignerStartEventArgs e); public class AuthenticodesignerStartEventArgs : EventArgs { public int SpecifiedChecksum { get; } public int ActualChecksum { get; } public bool IsSigned { get; } public bool Cancel { get; set; } }
Public Event OnStart As OnStartHandler Public Delegate Sub OnStartHandler(sender As Object, e As AuthenticodesignerStartEventArgs) Public Class AuthenticodesignerStartEventArgs Inherits EventArgs Public ReadOnly Property SpecifiedChecksum As Integer Public ReadOnly Property ActualChecksum As Integer Public ReadOnly Property IsSigned As Boolean Public Property Cancel As Boolean End Class
Remarks
This event marks the start of the signing process over a certain file.
SpecifiedChecksum is the checksum specified in the file itself, ActualChecksum is the actual checksum computed by the component, IsSigned specifies whether the file is already signed, and Cancel allows to stop the operation.
TLSCertValidate Event (AuthenticodeSigner Component)
This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.
Syntax
public event OnTLSCertValidateHandler OnTLSCertValidate; public delegate void OnTLSCertValidateHandler(object sender, AuthenticodesignerTLSCertValidateEventArgs e); public class AuthenticodesignerTLSCertValidateEventArgs : EventArgs { public string ServerHostname { get; } public string ServerIP { get; } public bool Accept { get; set; } }
Public Event OnTLSCertValidate As OnTLSCertValidateHandler Public Delegate Sub OnTLSCertValidateHandler(sender As Object, e As AuthenticodesignerTLSCertValidateEventArgs) Public Class AuthenticodesignerTLSCertValidateEventArgs Inherits EventArgs Public ReadOnly Property ServerHostname As String Public ReadOnly Property ServerIP As String Public Property Accept As Boolean End Class
Remarks
This event is fired during a TLS handshake. Use TLSServerChain property to access the certificate chain. In general case, components may contact a number of TLS endpoints during their work, depending on their configuration.
Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.
ValidationProgress Event (AuthenticodeSigner Component)
TBD
Syntax
public event OnValidationProgressHandler OnValidationProgress; public delegate void OnValidationProgressHandler(object sender, AuthenticodesignerValidationProgressEventArgs e); public class AuthenticodesignerValidationProgressEventArgs : EventArgs { public string ValidationEventType { get; } public string Cert { get; } public string CACert { get; } public bool DoContinue { get; set; } }

|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
KeyID String |
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 extra protection layer for the protocol and diminishes the risk of 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:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
KeySecret String |
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. |

RevocationCheck RevocationCheckKinds |
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. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential. |

Configuration Settings (AuthenticodeSigner 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.AuthenticodeSigner Configuration Settings
AttributeConflictResolution:
Specifies how to resolve updating conflicts.Use this property to specify what to do when a custom unsigned attribute with the same OID already exists. Default: tcrInsert. Available options are:
|
|||||||||||||
| BufferSize: Specifies processing buffer size in bytes.Use this property to set the buffer size (in bytes) that should be used when processing binaries. The default value is 1048576 (1 MB). | |||||||||||||
| ForceCompleteChainValidationForTrusted: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors. Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments. | |||||||||||||
| GracePeriod: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated. | |||||||||||||
| IgnoreOCSPNoCheckExtension: Whether OCSP NoCheck extension should be ignored.Set this property to false to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues. | |||||||||||||
| IgnoreSystemTrust:
Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the component should respect
the trust to CA certificates as configured in the operating system.
In Windows this effectively defines whether the component should trust the
certificates residing in the Trusted Root Certification Authorities store.
If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as TrustedCertificates property) are considered trusted. |
|||||||||||||
| ImplicitlyTrustSelfSignedCertificates: Whether to trust self-signed certificates. Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows to emulate the verifying environment without actually changing its security settings. | |||||||||||||
| PromoteLongOCSPResponses: Whether long OCSP responses are requested. Set this property to True to force the component to publish 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted. | |||||||||||||
| TempPath: Path for storing temporary files.This setting specifies an absolute path to the location on disk where temporary files are stored. | |||||||||||||
TimestampConflictResolution:
Specifies how to resolve timestamping conflicts.Use this property to specify how timestamping conflicts should be resolved. Default value: tcrIgnore. Available options are:
|
|||||||||||||
| TimestampResponse: A base16-encoded timestamp response received from a TSA.When using virtual:// timestamp endpoints, assign this property in your Notification event handler with the TSP response that you receive from the TSA. Remember to encode the response in hex (base16). | |||||||||||||
| TLSChainValidationDetails: Contains the advanced details of the TLS server certificate validation.Check this property in TLSCertValidate event handler to access the TLS certificate validation details. | |||||||||||||
| TLSChainValidationResult: Contains the result of the TLS server certificate validation.Check this property in TLSCertValidate event handler to obtain the TLS certificate validation result. | |||||||||||||
| TLSClientAuthRequested: Indicates whether the TLS server requests client authentication.Check this property in TLSCertValidate event handler to find out whether the TLS server requests the client to provide the authentication certificate. If this property is set to true, provide your certificate via TLSClientChain property. Note that the component may fire this event more than once during each operation, as more than one TLS-enabled server may need to be contacted. | |||||||||||||
| TLSValidationLog: Contains the log of the TLS server certificate validation.Check this property in TLSCertValidate event handler to retrieve the validation log of the TLS server. | |||||||||||||
| TolerateMinorChainIssues: Whether to tolerate minor chain issues.TBD | |||||||||||||
| UseMicrosoftCTL: Enables or disables automatic use of Microsoft online certificate trust list.Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository. | |||||||||||||
| UseSystemCertificates: Enables or disables the use of the system certificates.Use this property to tell chain validation module automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework. |
Base Configuration 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:
|

| 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. |
|||||||||||||||||||||||||||||||

| 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:
|
|||||||||||||||||||||||||||||||
| 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. | |||||||||||||||||||||||||||||||
| Tag: Allows to store any custom data.Use this config property to store any custom data. | |||||||||||||||||||||||||||||||
| 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. |
