The PDFEncryptor component encrypts PDF documents.

Syntax

TsbxPDFEncryptor

Remarks

PDFEncryptor encrypts PDF documents with passwords or certificates.

Use PDFEncryptor to encrypt unencrypted and unsigned PDF documents. The PDF specification offers two encryption types:

• Password-based encryption: only someone who knows the password can decrypt the document.
• Certificate-based encryption: only the person who has the private key matching the encryption certificate can decrypt the document.

To encrypt a document with a password, simply assign the password to OwnerPassword and UserPassword properties. While PDF allows you to use different passwords for less-restricted owner and more-restricted user, this is rarely used in practice, with the majority of implementations sticking to the same password for both types of users.

To encrypt a document with a certificate, load the recipient's certificate using CertificateManager or CertificateStorage components and assign it to the EncryptionCertificate property. The certificate does not need to include the private key.

For both encryption types, use Permissions setting to adjust what the viewer can and cannot do. Please note that those are largely declarative, and when a PDF viewing application gets access to the decryption password, it can violate them or simply re-save the document without encryption.

Use EncryptionAlgorithm property to tweak the encryption algorithm. EncryptMetadata specifies whether the document information (author name, producer software etc.) should be encrypted together with the rest of the document or kept in the clear.

Finally, provide the input and output locations using InputFile (or InputBytes) and OutputFile properties and call the Encrypt method to complete the operation. If OutputFile is not assigned, the encrypted document will be generated in OutputBytes. encryptor.InputFile = "plain.pdf"; encryptor.OutputFile = "encrypted.pdf"; encryptor.OwnerPassword = "password"; encryptor.UserPassword = "password"; encryptor.Permissions = pepLowQualityPrint | pepHighQualityPrint; encryptor.Encrypt();

EncryptionCertificateCA Property (PDFEncryptor Component)

Indicates whether the certificate has a CA capability.

Syntax

__property bool EncryptionCertificateCA = { read=FEncryptionCertificateCA, write=FSetEncryptionCertificateCA };

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.

This property is not available at design time.

Data Type

Boolean

EncryptionCertificateCAKeyID Property (PDFEncryptor Component)

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

Syntax

__property DynamicArray EncryptionCertificateCAKeyID = { read=FEncryptionCertificateCAKeyID };

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 EncryptionCertificateSubjectKeyID 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

EncryptionCertificateCertType Property (PDFEncryptor 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.

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

Syntax

__property String EncryptionCertificateFriendlyName = { read=FEncryptionCertificateFriendlyName };

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.

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

Data Type

String

EncryptionCertificateHandle Property (PDFEncryptor Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Syntax

__property __int64 EncryptionCertificateHandle = { read=FEncryptionCertificateHandle, write=FSetEncryptionCertificateHandle };

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());

This property is not available at design time.

Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the EncryptionCertificatePublicKeyBytes or EncryptionCertificatePrivateKeyBytes property would typically contain auxiliary values, and therefore be longer.

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

Data Type

Integer

EncryptionCertificateKeyFingerprint Property (PDFEncryptor Component)

Returns a SHA1 fingerprint of the public key contained in the certificate.

Syntax

__property String EncryptionCertificateKeyFingerprint = { read=FEncryptionCertificateKeyFingerprint };

Default Value

""

Remarks

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

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

This property is not available at design time.

Data Type

String

EncryptionCertificatePrivateKeyBytes Property (PDFEncryptor Component)

Returns the certificate's private key in DER-encoded format.

Syntax

__property DynamicArray EncryptionCertificatePrivateKeyBytes = { read=FEncryptionCertificatePrivateKeyBytes };

Remarks

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

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

Data Type

Byte Array

EncryptionCertificatePrivateKeyExists Property (PDFEncryptor Component)

Indicates whether the certificate has a usable private key associated with it.

Syntax

__property bool EncryptionCertificatePrivateKeyExists = { read=FEncryptionCertificatePrivateKeyExists };

Default Value

false

Remarks

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from EncryptionCertificatePrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

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

Config Method (PDFEncryptor Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

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.

__property TsbxPDFEncryptorDocumentLoadedEvent OnDocumentLoaded = { read=FOnDocumentLoaded, write=FOnDocumentLoaded };

Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the Pages information to find the optimal position for the signature widget.

Set Cancel to true to terminate document processing on this stage.

Error Event (PDFEncryptor Component)

Information about errors during encryption.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TsbxPDFEncryptorErrorEventParams;
typedef void __fastcall (__closure *TsbxPDFEncryptorErrorEvent)(System::TObject* Sender, TsbxPDFEncryptorErrorEventParams *e);
__property TsbxPDFEncryptorErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The event is fired in case of exceptional conditions during PDF processing.

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

Notification Event (PDFEncryptor Component)

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

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxPDFEncryptorNotificationEventParams;
typedef void __fastcall (__closure *TsbxPDFEncryptorNotificationEvent)(System::TObject* Sender, TsbxPDFEncryptorNotificationEventParams *e);
__property TsbxPDFEncryptorNotificationEvent 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.

This component can fire this event with the following EventID values:

Config Settings (PDFEncryptor Component)

The component accepts one or more of the following configuration settings. Configuration 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.
