The CertificateManager module supports importing, exporting, and generating X.509 certificates.

Syntax

SecureBlackbox.Certificatemanager

Remarks

Usage of this class includes importing and exporting certificates and keys in various formats, as well as certificate generation.

Loading certificates

To load a certificate from a file, use the ImportFromFile method. This method supports all existing certificate formats, including PFX, PEM, DER, and P7B. Note that keys contained in PFX and PEM certificates are often encrypted with a password, so you will likely need to provide one for the certificate to be loaded correctly. You can either provide the password via the method's parameter, or provide it on-demand by subscribing to the PasswordNeeded event.

Alternatively, you can use ImportCert to load a certificate from a different type of media, such as a database.

If your certificate and its private key are stored in separate files or buffers - which is often the case where PEM or DER format is used - please load the certificate with the ImportFromFile method first, and then add the key to it with a separate call to the ImportKeyFromFile method. You can mix and match the certificate and key formats in this case; CertificateManager will handle this automatically.

Note that CertificateManager can only keep one certificate at a time. If your PFX or PEM file contains more than one certificate, use CertificateStorage component to load it instead.

Generating certificates

• set all the needed certificate properties - for example, its subject, serial number, and validity period - via the Certificate property.
• load the CA certificate to a different CertificateManager object, and assign it to the CACertificate property. Note that the CA certificate should have an associated private key. Alternatively, the CA certificate can be loaded using a CertificateStorage object, which allows to import it from a hardware device or a system store.

  Note: you do not need to load and set the CA certificate if generating a self-signed certificate.

• Call Generate to generate a new keypair and wrap it into a certificate.
• Save the certificate using ExportToFile or ExportCert methods.

  Note: take care to choose a format that supports storing private keys. If you do not save the new private key at this stage, you won't be able to recover it later.

  Note: you can save the private key separately using the ExportKey method.

- (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 (CertificateManager Module)

ExportKey specifies whether to export the private key together with the certificate. Pass the encryption password via the Password parameter if needed.

Note that not all formats support encryption, and some (like PEM) only support partial encryption (key only). Keep this in mind when considering which format to choose for storing your certificates.

ExportCSR Method (CertificateManager Module)

Exports a Certificate Signing Request (CSR).

Syntax

• Swift
• Objective-C

public func exportCSR(format: Int32) throws -> Data

Generate Method (CertificateManager Module)

Generates a new certificate.

Syntax

• Swift
• Objective-C

public func generate(keyBits: Int32) throws -> Void

- (void)generate:(int)keyBits;

Remarks

Call this method to generate a new certificate based on the information provided via Certificate, CACertificate, and CertificateRequest parameters as given below:

If neither CACertificate nor CertificateRequest are set, a self-signed certificate will be generated based on the information set up in Certificate object.

If CACertificate is provided but CertificateRequest is not, a certificate signed by the CA certificate will be generated based on the information configured in the Certificate object.

If both CACertificate and CertificateRequest are set, a certificate based on the certificate request and signed by the CA certificate will be generated. The private key contained in the certificate request will be used.

KeyBits specifies the number of bits in the key to be generated. Note that this property is ignored in the case of request-based generation.

GenerateAsyncBegin Method (CertificateManager Module)

Initiates asynchronous (DC) certificate generation.

Syntax

• Swift
• Objective-C

public func generateAsyncBegin(keyBits: Int32) throws -> String

- (NSString*)generateAsyncBegin:(int)keyBits;

Remarks

Call this method to initiate an asynchronous certificate generation process. Pass the obtained async state to the DC server for signing. To finalize the generation, pass the async state received from the DC server to GenerateAsyncEnd.

AsyncState is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the 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 class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

GenerateAsyncEnd Method (CertificateManager Module)

Completes asynchronous certificate generation.

Syntax

• Swift
• Objective-C

public func generateAsyncEnd(asyncReply: String) throws -> Void

- (void)generateAsyncEnd:(NSString*)asyncReply;

Remarks

Call this method to finalize the asynchronous generation process and pass the async state received from DC server via AsyncReply parameter.

AsyncState is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the 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.

You then send the async state to the DC server (often represented by the DCAuth class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

GenerateCSR Method (CertificateManager Module)

Creates a new certificate signing request (CSR).

Syntax

• Swift
• Objective-C

public func generateCSR(keyBits: Int32) throws -> Void

- (void)generateCSR:(int)keyBits;

Remarks

Call this method to generate a new certificate request with the specified parameters. The newly generated CSR is saved in CertificateRequest property. Use ExportCSR and ExportKey to serialize the generated objects.

GenerateExternal Method (CertificateManager Module)

Generates a new certificate or request with an external signing device.

Syntax

• Swift
• Objective-C

public func generateExternal(csr: Bool, keyBytes: Data, keyPassword: String) throws -> Void

- (void)generateExternal:(BOOL)CSR :(NSData*)keyBytes :(NSString*)keyPassword;

Remarks

Call this method to generate a new certificate based on the information provided via Certificate, CACertificate, and CertificateRequest parameters as given below:

If CACertificate is provided but CertificateRequest is not, a certificate signed by the CA certificate will be generated based on the information configured in the Certificate object.

If both CACertificate and CertificateRequest are set, a certificate based on the certificate request and signed by the CA certificate will be generated. The private key contained in the certificate request will be used.

If neither CACertificate nor CertificateRequest are set, an exception will be thrown: only CA-issued certificates can be generated remotely.

KeyBits specifies the number of bits in the key to be generated. Note that this property is ignored in the case of request-based generation.

Use it as a quick method to get a working certificate to evaluate or test a piece of functionality that relies on certificates. The certificate will use pre-defined settings for most of its fields; use Generate method to generate bespoke real-world certificates. Purpose specifies the intended use of certificate:

• "generic": a generic certificate with no specific purpose
• "tls": a TLS server certificate
• "tls-client": a client-side TLS certificate
• "email": a secure e-mail (S/MIME) certificate

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

Reports exceptional conditions during certificate loading, exporting, or validation.

ErrorCode contains an error code and Description contains a textual description of the error.

ExternalSign Event (CertificateManager 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 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(); };

Notification Event (CertificateManager 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 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.

PasswordNeeded Event (CertificateManager Module)

This event is fired when a decryption password is needed.

Syntax

• Swift
• Objective-C

func onPasswordNeeded(password: inout String, cancel: inout Bool)

- (void)onPasswordNeeded:(NSString**)password :(int*)cancel;

Remarks

The class fires this event when a password is needed to decrypt a certificate or a private key.

In the handler of this event, assign the password to the Password parameter, or set Cancel to true to abort the operation.

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.

CertificateRequest Type

Provides access to details of an individual certificate request (CSR).

Remarks

This type represents a certificate request as defined in PKCS#10.

Fields

Constructors

public init()

Creates a new object with default field values.

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.
