Syntax

MailWriter

Remarks

Use MailWriter to compose, sign, and encrypt e-mail messages, and prepare them for sending or saving.

Preparing a very simple message and saving it to a file: MailWriter writer = new MailWriter(); writer.From.Add(new MailAddress("John Doe", "jdoe@company.com")); writer.SendTo.Add(new MailAddress("Mary Dow", "mdow@home.com")); writer.Message.Subject = "Lating to the party"; writer.Message.PlainText = "Hi Mary!\r\nStill in the office waiting for my partner.\r\nProbably I'll be late to the party for about an hour.\r\nSorry.\r\nJohn"; writer.SaveToFile("path\\message.eml");

Attaching an image and referencing it from the message text: writer.AttachImage("myimage", File.ReadAllBytes("path\\image.jpg")); writer.Attachments[0].ContentSubtype = "jpeg"; writer.Message.HtmlText = "<html><body>Message with an image<p><img src=\"cid:myimage\"></body></html>";

Signing a message with a certificate (note that the certificate should contain its private key): CertificateManager manager = new CertificateManager(); manager.ImportFromFile("path\\cert.pfx", "password"); writer.SecuritySettings.Sign = true; writer.SecuritySettings.HashAlgorithm = "SHA256"; writer.SigningCertificate = manager.Certificate; writer.SaveToFile("path\\message.eml");

Encrypting a message with one or more certificates (no private key is required): CertificateManager manager = new CertificateManager(); manager.ImportFromFile("path\\cert.cer", ""); writer.SecuritySettings.Encrypt = true; writer.SecuritySettings.EncryptionAlgorithm = "AES256"; writer.EncryptionCertificates.Add(manager.Certificate); // add more certificates if needed writer.SaveToFile("D:\\test.eml");

Unicode (Windows) virtual INT FireError(MailWriterErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } MailWriterErrorEventParams;
#define EID_MAILWRITER_ERROR 1

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class MailWriterErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Error(MailWriterErrorEventParams *e);
// Or, subclass MailWriter and override this emitter function. virtual int FireError(MailWriterErrorEventParams *e) {...}

Remarks

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

ExternalSign Event (MailWriter Class)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

ANSI (Cross Platform)
virtual int FireExternalSign(MailWriterExternalSignEventParams *e);
typedef struct {
const char *OperationId;
const char *HashAlgorithm;
const char *Pars;
const char *Data;
char *SignedData; int reserved; } MailWriterExternalSignEventParams;
Unicode (Windows) virtual INT FireExternalSign(MailWriterExternalSignEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR HashAlgorithm;
LPCWSTR Pars;
LPCWSTR Data;
LPWSTR SignedData; INT reserved; } MailWriterExternalSignEventParams;
#define EID_MAILWRITER_EXTERNALSIGN 2

virtual INT SECUREBLACKBOX_CALL FireExternalSign(LPSTR &lpszOperationId, LPSTR &lpszHashAlgorithm, LPSTR &lpszPars, LPSTR &lpszData, LPSTR &lpszSignedData);
class MailWriterExternalSignEventParams {
public:
  const QString &OperationId();

  const QString &HashAlgorithm();

  const QString &Pars();

  const QString &Data();

  const QString &SignedData();
  void SetSignedData(const QString &qsSignedData);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ExternalSign(MailWriterExternalSignEventParams *e);
// Or, subclass MailWriter and override this emitter function. virtual int FireExternalSign(MailWriterExternalSignEventParams *e) {...}

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

Notification Event (MailWriter Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireNotification(MailWriterNotificationEventParams *e);
typedef struct {
const char *EventID;
const char *EventParam; int reserved; } MailWriterNotificationEventParams;
Unicode (Windows) virtual INT FireNotification(MailWriterNotificationEventParams *e);
typedef struct {
LPCWSTR EventID;
LPCWSTR EventParam; INT reserved; } MailWriterNotificationEventParams;
#define EID_MAILWRITER_NOTIFICATION 3

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);
class MailWriterNotificationEventParams {
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(MailWriterNotificationEventParams *e);
// Or, subclass MailWriter and override this emitter function. virtual int FireNotification(MailWriterNotificationEventParams *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.

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.

The following fields are available:

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:

ckuUnknown0x00000Unknown key usage

ckuDigitalSignature0x00001Digital signature

ckuNonRepudiation0x00002Non-repudiation

ckuKeyEncipherment0x00004Key encipherment

ckuCodeSigning0x00800Code signing

ckuEmailProtection0x01000Email protection

ckuTimeStamping0x02000Timestamping

ckuOCSPSigning0x04000OCSP signing

ckuSmartCardLogon0x08000Smartcard logon

ckuKeyPurposeClientAuth0x10000Kerberos - client authentication

ckuKeyPurposeKDC0x20000Kerberos - 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.

The following fields are available:

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.

SB_HASH_ALGORITHM_SHAKE_256_LENSHAKE_256_LEN

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.

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the MailWriter class.

Methods

GetCount This method returns the current size of the collection.

int GetCount() {}

SetCount This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.

int SetCount(int count) {}

Get This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.

T* Get(int index) {}

Set This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.

T* Set(int index, T* value) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The MailWriter class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the MailWriter class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

This method is called automatically when a SecureBlackboxStream object is deleted.

Flush Forces all data held by the stream's buffers to be written out to storage.

int Flush() { return 0; }

Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0.

Read Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.

int Read(void* buffer, int count) = 0;

Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream.

Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed.

Seek Sets the current position within the stream based on a particular point of origin.

int64 Seek(int64 offset, int seekOrigin) = 0;

Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:

  • 0: Seek from beginning.
  • 1: Seek from current position.
  • 2: Seek from end.

Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged.

Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported.

Write Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.

int Write(const void* buffer, int count) = 0;

Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream.

Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (MailWriter Class)

The class 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 class, access to these internal properties is provided through the Config method.

MailWriter Config Settings

BitsInKey:   Key length for the block cipher used for encryption. The value should be a multiple of 8.

IncludeSigningCertificate:   If true (by default), the signing certificate is included into the signature. Otherwise, it is included only if SigningChain is not empty.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

Base Config Settings

ASN1UseGlobalTagCache:   Controls whether ASN.1 module should use a global object cache.

This is a performance setting. It is unlikely that you will ever need to adjust it.

AssignSystemSmartCardPins:   Specifies whether CSP-level PINs should be assigned to CNG keys.

This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

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.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:

offNo caching (default)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the class.

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations:   Specifies the default key derivation algorithm iteration count.

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.

DNSLocalSuffix:   The suffix to assign for TLD names.

Use this global setting to adjust the default suffix to assign to top-level domain names. The default is .local.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

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.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

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".

HardwareCryptoUsePolicy:   The hardware crypto usage policy.

This global setting controls the hardware cryptography usage policy: auto, enable, or disable.

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

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.

HttpVersion:   The HTTP version to use in any inner HTTP client components created.

Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.

IgnoreExpiredMSCTLSigningCert:   Whether to tolerate the expired Windows Update signing certificate.

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.

ListDelimiter:   The delimiter character for multi-element lists.

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.

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

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.

LogRotationMode:   Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

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.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

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.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

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.

OldClientSideRSAFallback:   Specifies whether the SSH client should use a SHA1 fallback.

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.

ProductVersion:   Returns the version of the SecureBlackbox library.

This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

ServerSSLDHKeyLength:   Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

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.

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).

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).

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.

Trappable Errors (MailWriter Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
