Byte Array

CertCA Property (MessageVerifier Component)

Indicates whether the certificate has a CA capability.

Syntax

__property bool CertCA[int CertIndex] = { read=FCertCA };

Default Value

false

Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

The CertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

This property is read-only and not available at design time.

Data Type

Boolean

CertCAKeyID Property (MessageVerifier Component)

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Syntax

__property DynamicArray CertCAKeyID[int CertIndex] = { read=FCertCAKeyID };

Remarks

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the CertSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The CertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

This property is read-only and not available at design time.

Data Type

Byte Array

CertCertType Property (MessageVerifier Component)

  ctX509Certificate=1,
  ctX509CertificateRequest=2
};

Default Value

ctUnknown

Remarks

Returns the type of the entity contained in the Certificate object.

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager component to load or create new certificate and certificate requests objects.

The CertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

This property is read-only and not available at design time.

Syntax

__property String CertFriendlyName[int CertIndex] = { read=FCertFriendlyName };

Default Value

""

Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

The CertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

This property is read-only and not available at design time.

Data Type

Default Value

0

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

The CertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

This property is read-only and not available at design time.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the TSACertSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

This property is read-only and not available at design time.

Data Type

Byte Array

Verify Method (MessageVerifier Component)

Verifies digitally signed data.

Syntax

void __fastcall Verify();

Remarks

PKCS#7 and its successor, CMS, support two types of signatures: (1) enveloping signatures, where the signed data and its signature are combined in the same message, and (2) detached signatures, where the signature is stored as a separate entity. This method verifies enveloped signatures and extracts data contained in them. Use VerifyDetached to verify detached signatures.

This method expects the enveloping signature to be provided via InputFile or InputStream properties.

Note that this method only checks the integrity of the signature, i.e., that it is signed with the claimed certificate and has not been altered. It does not validate the signing certificate chain. To validate the certificate chain, either use CertificateValidator component together with MessageVerifier, or consider using CAdESVerifier component instead.

VerifyDetached Method (MessageVerifier Component)

Verifies a detached signature.

Syntax

void __fastcall VerifyDetached();

Remarks

Use this method to verify detached signatures. Pass the signature via InputFile (or InputStream) property, and the original data via DataFile (DataStream).

__property TsbxMessageVerifierNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

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 the 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.

RecipientFound Event (MessageVerifier Component)

Fires to report a message addressee parameters.

Syntax

typedef struct {
  String IssuerRDN;
  DynamicArray SerialNumber;
