PDFEncryptor Module

Properties Methods Events Config Settings Errors

The PDFEncryptor module encrypts PDF documents.

Syntax

SecureBlackbox.PDFEncryptor

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();

Config Method (PDFEncryptor Module)

Sets or retrieves a configuration setting.

Syntax

Swift
Objective-C

public func config(configurationString: String) throws -> String

- (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 (PDFEncryptor Module)

Performs an additional action.

Syntax

Swift
Objective-C

public func doAction(actionID: String, actionParams: String) throws -> String

- (NSString*)doAction:(NSString*)actionID :(NSString*)actionParams;

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Common ActionIDs:


Action	Parameters	Returned value	Description
ResetTrustedListCache	none	none	Clears the cached list of trusted lists.
ResetCertificateCache	none	none	Clears the cached certificates.
ResetCRLCache	none	none	Clears the cached CRLs.
ResetOCSPResponseCache	none	none	Clears the cached OCSP responses.

Encrypt Method (PDFEncryptor Module)

Encrypts the PDF document.

Syntax

Swift
Objective-C

public func encrypt() throws -> Void

- (void)encrypt;

Remarks

Use this method to encrypt the PDF document as configured in the object's properties.

Reset Method (PDFEncryptor Module)

Resets the component settings.

Syntax

Swift
Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

Reset is a generic method available in every class.

DocumentLoaded Event (PDFEncryptor Module)

This event is fired when the document has been loaded into memory.

Syntax

Swift
Objective-C

func onDocumentLoaded(cancel: inout Bool)

- (void)onDocumentLoaded:(int*)cancel;

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 Module)

Information about errors during encryption.

Syntax

Swift
Objective-C

func onError(errorCode: Int32, description: String)

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

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 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.

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


DocumentLoaded	Notifies the application that the document has been loaded. This is a backward-compatibility-only notification. Use OnDocumentLoaded event instead.

Certificate Type

Encapsulates an individual X.509 certificate.

Remarks

This type keeps and provides access to X.509 certificate details.

The following fields are available:

Fields

bytes
Data (read-only)
Default Value: ""

Returns the raw certificate data in DER format.

ca
Bool
Default Value: False

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.

caKeyID
Data (read-only)
Default Value: ""

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 setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

certType
CertTypes (read-only)
Default Value: 0

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.

crlDistributionPoints
String
Default Value: ""

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

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.

curve
String
Default Value: ""

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

fingerprint
String (read-only)
Default Value: ""

Contains the fingerprint (a hash imprint) of this certificate.

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

friendlyName
String (read-only)
Default Value: ""

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.

handle
Int64
Default Value: 0

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());

hashAlgorithm
String
Default Value: ""

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use to find out the hash algorithm that is part of the certificate signature.

Use the , , and properties to get more details about the key the certificate contains.

keyBits
Int32 (read-only)
Default Value: 0

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 or property would typically contain auxiliary values, and therefore be longer.

keyFingerprint
String (read-only)
Default Value: ""

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

Note that the key fingerprint is different from the certificate fingerprint accessible via the property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

keyUsage
Int32
Default Value: 0

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:


ckuUnknown	`0x00000`	Unknown key usage
ckuDigitalSignature	`0x00001`	Digital signature
ckuNonRepudiation	`0x00002`	Non-repudiation
ckuKeyEncipherment	`0x00004`	Key encipherment
ckuDataEncipherment	`0x00008`	Data encipherment
ckuKeyAgreement	`0x00010`	Key agreement
ckuKeyCertSign	`0x00020`	Certificate signing
ckuCRLSign	`0x00040`	Revocation signing
ckuEncipherOnly	`0x00080`	Encipher only
ckuDecipherOnly	`0x00100`	Decipher only
ckuServerAuthentication	`0x00200`	Server authentication
ckuClientAuthentication	`0x00400`	Client authentication
ckuCodeSigning	`0x00800`	Code signing
ckuEmailProtection	`0x01000`	Email protection
ckuTimeStamping	`0x02000`	Timestamping
ckuOCSPSigning	`0x04000`	OCSP signing
ckuSmartCardLogon	`0x08000`	Smartcard logon
ckuKeyPurposeClientAuth	`0x10000`	Kerberos - client authentication
ckuKeyPurposeKDC	`0x20000`	Kerberos - KDC

Set this property before generating the certificate to propagate the key usage flags to the new certificate.

keyValid
Bool (read-only)
Default Value: False

Returns True if the certificate's key is cryptographically valid, and False otherwise.

ocspLocations
String
Default Value: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's Generate method to propagate it to the new certificate.

The OCSP locations 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.

ocspNoCheck
Bool
Default Value: False

Accessor to the value of the certificate's ocsp-no-check extension.

origin
Int32 (read-only)
Default Value: 0

Returns the location that the certificate was taken or loaded from.

policyIDs
String
Default Value: ""

Contains identifiers (OIDs) of the applicable certificate policies.

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.

privateKeyBytes
Data (read-only)
Default Value: ""

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.

privateKeyExists
Bool (read-only)
Default Value: False

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 , 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.

privateKeyExtractable
Bool (read-only)
Default Value: False

Indicates whether the private key is extractable (exportable).

publicKeyBytes
Data (read-only)
Default Value: ""

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

qualified
Bool (read-only)
Default Value: False

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

qualifiedStatements
QualifiedStatementsTypes
Default Value: 0

Returns a simplified qualified status of the certificate.

qualifiers
String (read-only)
Default Value: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

selfSigned
Bool (read-only)
Default Value: False

Indicates whether the certificate is self-signed (root) or signed by an external CA.

serialNumber
Data
Default Value: ""

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

sigAlgorithm
String (read-only)
Default Value: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

source
PKISources (read-only)
Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

subject
String (read-only)
Default Value: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via .

subjectAlternativeName
String
Default Value: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

The alternative names 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 element separator.

subjectKeyID
Data
Default Value: ""

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The and properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

subjectRDN
String
Default Value: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

valid
Bool (read-only)
Default Value: False

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

validFrom
String
Default Value: ""

The time point at which the certificate becomes valid, in UTC.

validTo
String
Default Value: ""

The time point at which the certificate expires, in UTC.

Constructors

StaticIPAddresses: Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag: Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup: Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

TLSSessionLifetime: Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval: Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

UseCRLObjectCaching: Specifies whether reuse of loaded CRL objects is enabled.

This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

UseInternalRandom: Switches between SecureBlackbox-own and platform PRNGs.

Allows to switch between internal/native PRNG implementation and the one provided by the platform.

UseLegacyAdESValidation: Enables legacy AdES validation mode.

Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

UseOCSPResponseObjectCaching: Specifies whether reuse of loaded OCSP response objects is enabled.

This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

UseOwnDNSResolver: Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemNativeSizeCalculation: An internal CryptoAPI access tweak.

This is an internal setting. Please do not use it unless instructed by the support team.

UseSystemOAEPAndPSS: Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom: Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

XMLRDNDescriptorName[OID]: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.

This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.
