Remarks

Use this control to validate XML-SIG signatures. XMLVerifier is capable of validating the integrity of the references covered by the signature and the integrity of the signature itself, using the certificate contained in the signature or provided from the user' code.

Note that this component only validates the cryptographic aspects of the signatures, but does not perform any chain of trust validation. As such, it is the task of your code to ensure that the signing certificate is good for its purpose and is trusted in your environment.

If you are looking to validate certificate trust in addition to the cryptographic capabilities, please consider using XAdESVerifier. XAdESVerifier provides full support for advanced signature ecosystem, including revocation and Trusted List checking, timing checks, and chain of trust validation.

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 (SecureBlackbox_XMLVerifier Class)

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

Object Oriented Interface

public function getCertCAKeyID($certindex);

Procedural Interface

secureblackbox_xmlverifier_get($res, 6 , $certindex);

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 (SecureBlackbox_XMLVerifier Class)

Object Oriented Interface

public function getCertCertType($certindex);

Procedural Interface

secureblackbox_xmlverifier_get($res, 7 , $certindex);

Default Value

0

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 class 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.

Data Type

Integer

CertCRLDistributionPoints Property (SecureBlackbox_XMLVerifier Class)

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

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

String

CertCurve Property (SecureBlackbox_XMLVerifier Class)

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

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

String

CertFriendlyName Property (SecureBlackbox_XMLVerifier Class)

Object Oriented Interface

public function getCertFriendlyName($certindex);

Procedural Interface

secureblackbox_xmlverifier_get($res, 11 , $certindex);

Default Value

''

Remarks

Contains an associated alias (friendly name) of the certificate.

Procedural Interface

secureblackbox_xmlverifier_get($res, 12 , $certindex);

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.
