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

Syntax

nsoftware.SecureBlackbox.CertificateManager

Remarks

Usage of this component 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 ImportBytes 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

• call CreateNew to initialize a new certificate template.
• set all the needed certificate properties - for example, its subject, serial number, and validity period - via the Certificate property. Some of these properties will be pre-set by the preceding CreateNew call.
• 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 ExportBytes 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.

The following is a list of config settings for the component with short descriptions. Click on the links for further details.

CACertificate Property (CertificateManager Component)

A container for the CA certificate.

Syntax

• C#
• VB.NET

public Certificate CACertificate { get; set; }

Public Property CACertificate As Certificate

Remarks

Use this property to supply the CA certificate when needed.

You need to assign a valid CA certificate when generating a new certificate (including renewals), and when validating existing certificates. In the former case the assigned CA certificate should include the private key.

This property is not available at design time.

Certificate Property (CertificateManager Component)

A container for the certificate object.

Syntax

• C#
• VB.NET

public Certificate Certificate { get; set; }

Public Property Certificate As Certificate

Remarks

Use this property to set or access the properties of the certificate object on which the action is to be performed.

This property is not available at design time.

ExternalCrypto Property (CertificateManager Component)

Provides access to external signing and DC parameters.

Syntax

• C#
• VB.NET

public ExternalCrypto ExternalCrypto { get; }

Public ReadOnly Property ExternalCrypto As ExternalCrypto

Remarks

Use this property to tune-up remote cryptography settings. SecureBlackbox supports two independent types of external cryptography: synchronous (based on the ExternalSign event) and asynchronous (based on the DC protocol and the DCAuth signing component).

This property is read-only.

FIPSMode Property (CertificateManager Component)

Reserved.

Syntax

• C#
• VB.NET

public bool FIPSMode { get; set; }

Public Property FIPSMode As Boolean

Default Value

False

Remarks

This property is reserved for future use.

Config Method (CertificateManager Component)

Sets or retrieves a configuration setting.

Syntax

• C#
• VB.NET

public string Config(string configurationString);

Public Function Config(ByVal ConfigurationString As String) As String

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.

CreateNew Method (CertificateManager Component)

Creates a template for a new certificate or CSR with a particular purpose in the Certificate property.

Syntax

• C#
• VB.NET

public void CreateNew(int certType, string purpose, string subject);

Public Sub CreateNew(ByVal CertType As Integer, ByVal Purpose As String, ByVal Subject As String)

Remarks

This method pre-generates a certificate template that matches the specified purpose. The created template has its subject and default extensions initialized according to the selected purpose. Use Generate method to complete the process by generating a new keypair and signing it with the CA certificate (if provided).

The CertType parameter specifies the type of the object that you need to create. This can be a certificate or a certificate request (CSR).

• "generic" or an empty string: a generic certificate with no specific purpose. No extensions are pre-generated.
• "tls": a TLS server certificate
• "tls-client": a client-side TLS certificate
• "email": a secure e-mail (S/MIME) certificate
• "digsig": a digital signature certificate

Subject specifies the common name to include in the certificate. It can be a string of arbitrary format (e.g. "*.domain.com"), or a formatted RDN (e.g. "/C=US/O=Big Company, Inc./CN=Accounts receivable").

Leave all parameters empty to generate an empty template.

DoAction Method (CertificateManager Component)

Performs an additional action.

Syntax

• C#
• VB.NET

public string DoAction(string actionID, string actionParams);

Public Function DoAction(ByVal ActionID As String, ByVal ActionParams As String) As String

Call this method to generate a new certificate based on the information provided in the Certificate and CACertificate properties:

If CACertificate is not set, a self-signed certificate or certificate request will be generated based on the information set up in Certificate object.

If Certificate contains a certificate, and CACertificate is set, a certificate signed by the CA certificate will be generated based on the information configured in the Certificate object. The resulting certificate will remain in Certificate

If Certificate contains a signed certificate request, and CACertificate is set, a certificate based on the certificate request and signed by the CA certificate will be generated.

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 Component)

Initiates asynchronous (DC) certificate generation.

Syntax

• C#
• VB.NET

public string GenerateAsyncBegin(int keyBits);

Public Function GenerateAsyncBegin(ByVal KeyBits As Integer) As String

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 component), 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 Component)

Completes asynchronous certificate generation.

Syntax

• C#
• VB.NET

public void GenerateAsyncEnd(string asyncReply);

Public Sub GenerateAsyncEnd(ByVal AsyncReply As String)

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.

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 component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

GenerateExternal Method (CertificateManager Component)

Generates a new certificate or request over an existing public key.

Syntax

• C#
• VB.NET

public void GenerateExternal(byte[] keyBytes, string keyPassword);

Public Sub GenerateExternal(ByVal KeyBytes As Byte(), ByVal KeyPassword As String)

Remarks

This method does exactly the same as Generate. The only difference is that instead of generating a new keypair, this method generates a new certificate over an existing keypair. See the rules of the Generate method to learn about parameter configurations for different generation scenarios.

Note: KeyBytes can contain a public or private key - as long as SecureBlackbox recognises the format, it will be processed.

  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 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(); };
