PDFDecryptor Class
Properties Methods Events Config Settings Errors
The PDFDecryptor class decrypts PDF documents.
Syntax
PDFDecryptor
Remarks
PDFDecryptor decrypts PDF documents encrypted with passwords or certificates.
Use PDFDecryptor to decrypt protected 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.
Decryption is often used not only to restrict access to the document content, but also to assign specific access permissions. Among such permissions are allowed printing quality, permission to modify or extract content, to fill in forms, and a few others.
To decrypt a document encrypted with a password, simply assign the password to Password property. If the provided password matches either one of the 'user' and 'owner' passwords, it will be used to decrypt the document. 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 decrypt a document encrypted with a certificate, load the recipient's certificate using CertificateManager or CertificateStorage components and assign it to the DecryptionCertificate property. The certificate needs to include the associated private key.
You can assign the decryption material before processing the document (if you know beforehand what type of encryption was used), or on-the-fly, upon discovery that a particular document is encrypted. To implement the latter approach, please subscribe to Encrypted event. This event can fire for one or more times, notifying you of each encryption method that was used to protect the document. You can then assign the password or certificate inside the event handler accordingly.
Once you have decrypted the document, use the PERMISSIONS> property to check the document permissions, and other properties of the DocumentInfo object to find out the encryption details.
Finally, provide the input and output locations using InputFile (or InputBytes) and OutputFile properties and call the Decrypt method to complete the operation. If OutputFile is not assigned, the encrypted document will be generated in OutputBytes.
decryptor.InputFile = "encrypted.pdf";
decryptor.OutputFile = "decrypted.pdf";
decryptor.Password = "password";
decryptor.Decrypt();

char* secureblackbox_pdfdecryptor_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
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.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Decrypt Method (PDFDecryptor Class)
Decrypts a PDF document.
Syntax
ANSI (Cross Platform) int Decrypt(); Unicode (Windows) INT Decrypt();
int secureblackbox_pdfdecryptor_decrypt(void* lpObj);
int Decrypt();
Remarks
Use this method to decrypt a PDF document provided via InputFile (InputStream). The decrypted document will be saved in OutputFile (OutputStream).
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DoAction Method (PDFDecryptor Class)
Performs an additional action.
Syntax
ANSI (Cross Platform) char* DoAction(const char* lpszActionID, const char* lpszActionParams); Unicode (Windows) LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams);
char* secureblackbox_pdfdecryptor_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);
QString DoAction(const QString& qsActionID, const QString& qsActionParams);
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. |
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Reset Method (PDFDecryptor Class)
Resets the class settings.
Syntax
ANSI (Cross Platform) int Reset(); Unicode (Windows) INT Reset();
int secureblackbox_pdfdecryptor_reset(void* lpObj);
int Reset();
Remarks
Reset is a generic method available in every class.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DocumentLoaded Event (PDFDecryptor Class)
This event is fired when the document has been loaded into memory.
Syntax
ANSI (Cross Platform) virtual int FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
typedef struct {
int Cancel; int reserved; } PDFDecryptorDocumentLoadedEventParams;
Unicode (Windows) virtual INT FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
typedef struct {
BOOL Cancel; INT reserved; } PDFDecryptorDocumentLoadedEventParams;
#define EID_PDFDECRYPTOR_DOCUMENTLOADED 1 virtual INT SECUREBLACKBOX_CALL FireDocumentLoaded(BOOL &bCancel);
class PDFDecryptorDocumentLoadedEventParams { public: bool Cancel(); void SetCancel(bool bCancel); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void DocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e) {...}
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.
Encrypted Event (PDFDecryptor Class)
Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.
Syntax
ANSI (Cross Platform) virtual int FireEncrypted(PDFDecryptorEncryptedEventParams *e);
typedef struct {
int CertUsed;
const char *IssuerRDN;
const char *SerialNumber; int lenSerialNumber;
const char *SubjectKeyID; int lenSubjectKeyID;
int NeedCredential;
int SkipThis; int reserved; } PDFDecryptorEncryptedEventParams;
Unicode (Windows) virtual INT FireEncrypted(PDFDecryptorEncryptedEventParams *e);
typedef struct {
BOOL CertUsed;
LPCWSTR IssuerRDN;
LPCSTR SerialNumber; INT lenSerialNumber;
LPCSTR SubjectKeyID; INT lenSubjectKeyID;
BOOL NeedCredential;
BOOL SkipThis; INT reserved; } PDFDecryptorEncryptedEventParams;
#define EID_PDFDECRYPTOR_ENCRYPTED 2 virtual INT SECUREBLACKBOX_CALL FireEncrypted(BOOL &bCertUsed, LPSTR &lpszIssuerRDN, LPSTR &lpSerialNumber, INT &lenSerialNumber, LPSTR &lpSubjectKeyID, INT &lenSubjectKeyID, BOOL &bNeedCredential, BOOL &bSkipThis);
class PDFDecryptorEncryptedEventParams { public: bool CertUsed(); const QString &IssuerRDN(); const QByteArray &SerialNumber(); const QByteArray &SubjectKeyID(); bool NeedCredential(); bool SkipThis(); void SetSkipThis(bool bSkipThis); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Encrypted(PDFDecryptorEncryptedEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireEncrypted(PDFDecryptorEncryptedEventParams *e) {...}
Remarks
The class fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.
This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the DecryptionCertificate or Password property (depending on the encryption method used), or sets SkipThis to true.
The CertUsed parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case, the IssuerRDN, SerialNumber, and SubjectKeyID parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own Encrypted event loop.
CertUsed set to false indicates that the document uses password encryption. In this case, provide the password via the Password property.
The NeedCredential parameter specifies whether the correct credential is already available to the class or still needs to be set. One example where NeedCredential would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the Password property to a known pre-defined value). If NeedCredential is set to true, you must provide the valid credential for the decryption process to succeed.
Error Event (PDFDecryptor Class)
Information about errors during signing/validation.
Syntax
ANSI (Cross Platform) virtual int FireError(PDFDecryptorErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } PDFDecryptorErrorEventParams;
Unicode (Windows) virtual INT FireError(PDFDecryptorErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } PDFDecryptorErrorEventParams;
#define EID_PDFDECRYPTOR_ERROR 3 virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class PDFDecryptorErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(PDFDecryptorErrorEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireError(PDFDecryptorErrorEventParams *e) {...}
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.
ExternalDecrypt Event (PDFDecryptor Class)
Handles remote or external decryption.
Syntax
ANSI (Cross Platform) virtual int FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
typedef struct {
const char *OperationId;
const char *Algorithm;
const char *Pars;
const char *EncryptedData;
char *Data; int reserved; } PDFDecryptorExternalDecryptEventParams;
Unicode (Windows) virtual INT FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR Algorithm;
LPCWSTR Pars;
LPCWSTR EncryptedData;
LPWSTR Data; INT reserved; } PDFDecryptorExternalDecryptEventParams;
#define EID_PDFDECRYPTOR_EXTERNALDECRYPT 4 virtual INT SECUREBLACKBOX_CALL FireExternalDecrypt(LPSTR &lpszOperationId, LPSTR &lpszAlgorithm, LPSTR &lpszPars, LPSTR &lpszEncryptedData, LPSTR &lpszData);
class PDFDecryptorExternalDecryptEventParams { public: const QString &OperationId(); const QString &Algorithm(); const QString &Pars(); const QString &EncryptedData(); const QString &Data(); void SetData(const QString &qsData); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void ExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e) {...}
Remarks
Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.
The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.
Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16
Notification Event (PDFDecryptor Class)
This event notifies the application about an underlying control flow event.

LPCWSTR EventParam; INT reserved; } PDFDecryptorNotificationEventParams;
#define EID_PDFDECRYPTOR_NOTIFICATION 5 virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);
class PDFDecryptorNotificationEventParams { public: const QString &EventID(); const QString &EventParam(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Notification(PDFDecryptorNotificationEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireNotification(PDFDecryptorNotificationEventParams *e) {...}
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.
Syntax
SecureBlackboxCertificate (declared in secureblackbox.h)
Remarks
This type keeps and provides access to X.509 certificate details.

Fields
Bytes
char* (read-only)
Default Value:
Returns the raw certificate data in DER format.
CA
int
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 field when generating a new certificate to have its Basic Constraints extension generated automatically.
CAKeyID
char* (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 SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.
CertType
int (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
char*
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 field 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
char*
Default Value: ""
Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Fingerprint
char* (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
char* (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
char*
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 SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Issuer
char* (read-only)
Default Value: ""
The common name of the certificate issuer (CA), typically a company name. This is part of a larger set of credentials available via IssuerRDN.
IssuerRDN
char*
Default Value: ""
A list of Property=Value pairs that uniquely identify the certificate issuer.
Example: /C=US/O=Nationwide CA/CN=Web Certification Authority
KeyAlgorithm
char*
Default Value: "0"
Specifies the public key algorithm of this certificate.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.
KeyBits
int (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 PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.
KeyFingerprint
char* (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 Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.
KeyUsage
int
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 field before generating the certificate to propagate the key usage flags to the new certificate.
KeyValid
int (read-only)
Default Value: FALSE
Returns True if the certificate's key is cryptographically valid, and False otherwise.
OCSPLocations
char*
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 field 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
int
Default Value: FALSE
Accessor to the value of the certificate's ocsp-no-check extension.
Origin
int (read-only)
Default Value: 0
Returns the location that the certificate was taken or loaded from.
PolicyIDs
char*
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 field 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
char* (read-only)
Default Value:
Returns the certificate's private key in DER-encoded format. It is normal for this field to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.
PrivateKeyExists
int (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 field is independent from PrivateKeyBytes, 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
int (read-only)
Default Value: FALSE
Indicates whether the private key is extractable (exportable).
PublicKeyBytes
char* (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
int (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
int
Default Value: 0
Returns a simplified qualified status of the certificate.
Qualifiers
char* (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
int (read-only)
Default Value: FALSE
Indicates whether the certificate is self-signed (root) or signed by an external CA.
SerialNumber
char*
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
char* (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
int (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
char* (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 SubjectRDN.
SubjectAlternativeName
char*
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 SubjectRDN 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
char*
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 SubjectKeyID and CAKeyID fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.
SubjectRDN
char*
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
int (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
char*
Default Value: ""
The time point at which the certificate becomes valid, in UTC.
ValidTo
char*
Default Value: ""
The time point at which the certificate expires, in UTC.
Constructors
Certificate()
Creates a new object with default field values.
ExternalCrypto Type
Specifies the parameters of external cryptographic calls.
Syntax
SecureBlackboxExternalCrypto (declared in secureblackbox.h)
Remarks
External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields
AsyncDocumentID
char*
Default Value: ""
Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.
Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component identify the correct signature in the returned batch of responses.
If using batched requests, make sure to set this property to the same value on both the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.
CustomParams
char*
Default Value: ""
Custom parameters to be passed to the signing service (uninterpreted).
Data
char*
Default Value: ""
Additional data to be included in the async state and mirrored back by the requestor.
ExternalHashCalculation
int
Default Value: FALSE
Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth class.
If set to true, the class will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.
HashAlgorithm
char*
Default Value: "SHA256"
Specifies the request's signature hash algorithm.

KeyID
char*
Default Value: ""
The ID of the pre-shared key used for DC request authentication.
Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret to pass the key itself.
The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.
Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.
Example:
signer.ExternalCrypto.KeyID = "MainSigningKey";
signer.ExternalCrypto.KeySecret = "abcdef0123456789";
KeySecret
char*
Default Value: ""
The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.
Read more about configuring authentication in the KeyID topic.
Method
int
Default Value: 0
Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.
Available options:
asmdPKCS1 | 0 |
asmdPKCS7 | 1 |
Mode
int
Default Value: 0
Specifies the external cryptography mode.
Available options:
ecmDefault | The default value (0) |
ecmDisabled | Do not use DC or external signing (1) |
ecmGeneric | Generic external signing with the OnExternalSign event (2) |
ecmDCAuth | DCAuth signing (3) |
ecmDCAuthJSON | DCAuth signing in JSON format (4) |
PublicKeyAlgorithm
char*
Default Value: ""
Provide the public key algorithm here if the certificate is not available on the pre-signing stage.

Base Config Settings
This is a performance setting. It is unlikely that you will ever need to adjust it.
This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.
This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.
You can switch this property off to improve performance if your project only uses known, good private keys.
Set this property to enable or disable cookies caching for the class.
Supported values are:
off | No caching (default) | |
local | Local caching | |
global | Global caching |
Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.
This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.
Use this global setting to adjust the default suffix to assign to top-level domain names. The default is .local.
This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.
This setting only applies to sessions negotiated with TLS version 1.3.
Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".
This global setting controls the hardware cryptography usage policy: auto, enable, or disable.
This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes.
Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.
It is not uncommon for Microsoft Windows Update Certificate Trust List to be signed with an expired Microsoft certificate. Setting this global property to true makes SBB ignore the expired factor and take the Trust List into account.
Allows to set the delimiter for any multi-entry values returned by the component as a string object, such as file lists. For most of the components, this property is set to a newline sequence.
Contains a comma-separated list of values that specifies where debug log should be dumped.
Supported values are:
file | File | |
console | Console | |
systemlog | System Log (supported for Android only) | |
debugger | Debugger (supported for VCL for Windows and .Net) |

Use this property to set the log flush mode. The following values are defined:
none | No flush (caching only) | |
immediate | Immediate flush (real-time logging) | |
maxcount | Flush cached entries upon reaching LogMaxEventCount entries in the cache. |
Use this property to provide the desired debug log level.

none | None (by default) | |
fatal | Severe errors that cause premature termination. | |
error | Other runtime errors or unexpected conditions. | |
warning | Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". | |
info | Interesting runtime events (startup/shutdown). | |
debug | Detailed information on flow of through the system. | |
trace | More detailed information. |
Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.
The default value of this setting is 100.
Use this property to set the log rotation mode. The following values are defined:
none | No rotation | |
deleteolder | Delete older entries from the cache upon reaching LogMaxEventCount | |
keepolder | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) |
This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.
This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.
This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.
Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.
The PKICache setting specifies which Public Key Infrastructure (PKI) elements should be cached to optimize performance and reduce retrieval times. It supports comma-separated values to indicate the specific types of PKI data that should be cached.
Supported Values:
certificate | Enables caching of certificates. |
crl | Enables caching of Certificate Revocation Lists (CRLs). |
ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |
Example (default value):
PKICache=certificate,crl,ocsp
In this example, the component caches certificates, CRLs, and OCSP responses.
The PKICachePath setting defines the file system path where cached PKI data (e.g., certificates, CRLs, OCSP responses and Trusted Lists) will be stored. This allows the system to persistently save and retrieve PKI cache data, even across application restarts.
The default value is an empty string - no cached PKI data is stored on disk.
Example:
PKICachePath=C:\Temp\cache
In this example, the cached PKI data is stored in the C:\Temp\cache directory.
This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).
Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.
Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.
Supported values are:
none | No static DNS rules (default) | |
local | Local static DNS rules | |
global | Global static DNS rules |
Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.
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.
Use this config property to store any custom data.
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.
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).
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).
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.
Allows to switch between internal/native PRNG implementation and the one provided by the platform.
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).
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.
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.
Set this global property to false to make each validation run use its own copy of system certificate stores.
This is an internal setting. Please do not use it unless instructed by the support team.
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.
Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.
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.
Syntax:
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
Where:
OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.
PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.
Alias1, Alias2, ...: Optional alternative names recognized during parsing.
Usage Examples:
Map OID 2.5.4.5 to SERIALNUMBER:
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.
Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).
Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
