CRLManager Module

Properties   Methods   Events   Config Settings   Errors  

The CRLManager module supports the importing, exporting, and validation of Certificate Revocation Lists (CRLs).

Syntax

SecureBlackbox.Crlmanager

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid for any number of reasons by the issuing certificate authority (CA). CRLs identify certificates by their serial numbers. Therefore, by knowing the certificate's SerialNumber, its validity status can be checked against a CRL.

Each CRL corresponds to one issuing point, and each Certificate Authority (CA) certificate can have a corresponding CRL which contains information about the certificates signed with this CA certificate.

CAs are not required to issue CRLs if other revocation or certificate status mechanisms are provided. Each CRL must contain the date by which the next CRL will be issued. This date is specified by the NextUpdate field.

- (int)add:(NSData*)serialNumber :(NSString*)revocationDate :(int)revocationReason;

Remarks

Note that a single CRL may only contain certificates issued by a single CA, and this CRL must be signed by that CA.

Clear Method (CRLManager Module)

Empties the CRL.

Syntax

• Swift
• Objective-C

public func clear() throws -> Void

- (void)clear;

Remarks

Use this method to remove all elements currently included in the CRL.

Config Method (CRLManager Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These 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.

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 (CRLManager Module)

Performs an additional action.

Syntax

• Swift
• Objective-C

public func doAction(actionID: String, actionParams: String) throws -> String

- (NSString*)doAction:(NSString*)actionID :(NSString*)actionParams;

Remarks

DoAction 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.

The unique identifier (case insencitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Download Method (CRLManager Module)

Syntax

• Swift
• Objective-C

public func download(url: String) throws -> Void

• Objective-C

public func getCertEntryIndex(serialNumber: Data) throws -> Int32

- (int)getCertEntryIndex:(NSData*)serialNumber;

Information about errors during CRL management.

ExternalSign Event (CRLManager Module)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

• Swift
• Objective-C

func onExternalSign(operationId: String, hashAlgorithm: String, pars: String, data: String, signedData: inout String)

- (void)onExternalSign:(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)signedData;

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 (CRLManager Module)

This event notifies the application about an underlying control flow event.

Syntax

• Swift
• Objective-C

func onNotification(eventID: String, eventParam: String)

- (void)onNotification:(NSString*)eventID :(NSString*)eventParam;

Remarks

The class 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.

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Constructors

public init(stream: )

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data.

public init()

Creates a new object with default field values.

CRL Type

Represents a Certificate Revocation List.

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

Fields

Constructors

public init()

Creates an empty CRL object.

CRLEntryInfo Type

Represents a single entry of a Certificate Revocation List (CRL).

Remarks

This object contains revocation information for a particular certificate entry in the CRL.

Fields

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

Constructors

public init()

Creates a new ExternalCrypto object with default field values.
