# MailWriter Class The MailWriter class composes, encrypts, and signs e-mail messages. ## Syntax ```text 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: ```text 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: ```text writer.AttachImage("myimage", File.ReadAllBytes("path\\image.jpg")); writer.Attachments[0].ContentSubtype = "jpeg"; writer.Message.HtmlText = "Message with an image

"; ``` Signing a message with a certificate (note that the certificate should contain its private key): ```text 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): ```text 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"); ``` ## Property List *The following is the full list of the properties of the class with short descriptions.

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: ```text 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](#mailwriter-class) Class) This event notifies the application about an underlying control flow event. ## Syntax ```text 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; ``` ## 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: - [Bytes](#Certificate_f_Bytes) - [CA](#Certificate_f_CA) - [CAKeyID](#Certificate_f_CAKeyID) - [CertType](#Certificate_f_CertType) - [CRLDistributionPoints](#Certificate_f_CRLDistributionPoints) - [Curve](#Certificate_f_Curve) - [Fingerprint](#Certificate_f_Fingerprint) - [FriendlyName](#Certificate_f_FriendlyName) - [Handle](#Certificate_f_Handle) - [HashAlgorithm](#Certificate_f_HashAlgorithm) - [Issuer](#Certificate_f_Issuer) - [IssuerRDN](#Certificate_f_IssuerRDN) - [KeyAlgorithm](#Certificate_f_KeyAlgorithm) - [KeyBits](#Certificate_f_KeyBits) - [KeyFingerprint](#Certificate_f_KeyFingerprint) - [KeyUsage](#Certificate_f_KeyUsage) - [KeyValid](#Certificate_f_KeyValid) - [OCSPLocations](#Certificate_f_OCSPLocations) - [OCSPNoCheck](#Certificate_f_OCSPNoCheck) - [Origin](#Certificate_f_Origin) - [PolicyIDs](#Certificate_f_PolicyIDs) - [PrivateKeyBytes](#Certificate_f_PrivateKeyBytes) - [PrivateKeyExists](#Certificate_f_PrivateKeyExists) - [PrivateKeyExtractable](#Certificate_f_PrivateKeyExtractable) - [PublicKeyBytes](#Certificate_f_PublicKeyBytes) - [Qualified](#Certificate_f_Qualified) - [QualifiedStatements](#Certificate_f_QualifiedStatements) - [Qualifiers](#Certificate_f_Qualifiers) - [SelfSigned](#Certificate_f_SelfSigned) - [SerialNumber](#Certificate_f_SerialNumber) - [SigAlgorithm](#Certificate_f_SigAlgorithm) - [Source](#Certificate_f_Source) - [Subject](#Certificate_f_Subject) - [SubjectAlternativeName](#Certificate_f_SubjectAlternativeName) - [SubjectKeyID](#Certificate_f_SubjectKeyID) - [SubjectRDN](#Certificate_f_SubjectRDN) - [Valid](#Certificate_f_Valid) - [ValidFrom](#Certificate_f_ValidFrom) - [ValidTo](#Certificate_f_ValidTo) ## 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](CertificateManager.md#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [SubjectKeyID](#Certificate_f_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](#certificate-type) object. A [Certificate](#certificate-type) 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](CertificateManager.md#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. | | | | | --- | --- | --- | | SB_EC_SECP112R1 | SECP112R1 | | | SB_EC_SECP112R2 | SECP112R2 | | | SB_EC_SECP128R1 | SECP128R1 | | | SB_EC_SECP128R2 | SECP128R2 | | | SB_EC_SECP160K1 | SECP160K1 | | | SB_EC_SECP160R1 | SECP160R1 | | | SB_EC_SECP160R2 | SECP160R2 | | | SB_EC_SECP192K1 | SECP192K1 | | | SB_EC_SECP192R1 | SECP192R1 | | | SB_EC_SECP224K1 | SECP224K1 | | | SB_EC_SECP224R1 | SECP224R1 | | | SB_EC_SECP256K1 | SECP256K1 | | | SB_EC_SECP256R1 | SECP256R1 | | | SB_EC_SECP384R1 | SECP384R1 | | | SB_EC_SECP521R1 | SECP521R1 | | | SB_EC_SECT113R1 | SECT113R1 | | | SB_EC_SECT113R2 | SECT113R2 | | | SB_EC_SECT131R1 | SECT131R1 | | | SB_EC_SECT131R2 | SECT131R2 | | | SB_EC_SECT163K1 | SECT163K1 | | | SB_EC_SECT163R1 | SECT163R1 | | | SB_EC_SECT163R2 | SECT163R2 | | | SB_EC_SECT193R1 | SECT193R1 | | | SB_EC_SECT193R2 | SECT193R2 | | | SB_EC_SECT233K1 | SECT233K1 | | | SB_EC_SECT233R1 | SECT233R1 | | | SB_EC_SECT239K1 | SECT239K1 | | | SB_EC_SECT283K1 | SECT283K1 | | | SB_EC_SECT283R1 | SECT283R1 | | | SB_EC_SECT409K1 | SECT409K1 | | | SB_EC_SECT409R1 | SECT409R1 | | | SB_EC_SECT571K1 | SECT571K1 | | | SB_EC_SECT571R1 | SECT571R1 | | | SB_EC_PRIME192V1 | PRIME192V1 | | | SB_EC_PRIME192V2 | PRIME192V2 | | | SB_EC_PRIME192V3 | PRIME192V3 | | | SB_EC_PRIME239V1 | PRIME239V1 | | | SB_EC_PRIME239V2 | PRIME239V2 | | | SB_EC_PRIME239V3 | PRIME239V3 | | | SB_EC_PRIME256V1 | PRIME256V1 | | | SB_EC_C2PNB163V1 | C2PNB163V1 | | | SB_EC_C2PNB163V2 | C2PNB163V2 | | | SB_EC_C2PNB163V3 | C2PNB163V3 | | | SB_EC_C2PNB176W1 | C2PNB176W1 | | | SB_EC_C2TNB191V1 | C2TNB191V1 | | | SB_EC_C2TNB191V2 | C2TNB191V2 | | | SB_EC_C2TNB191V3 | C2TNB191V3 | | | SB_EC_C2ONB191V4 | C2ONB191V4 | | | SB_EC_C2ONB191V5 | C2ONB191V5 | | | SB_EC_C2PNB208W1 | C2PNB208W1 | | | SB_EC_C2TNB239V1 | C2TNB239V1 | | | SB_EC_C2TNB239V2 | C2TNB239V2 | | | SB_EC_C2TNB239V3 | C2TNB239V3 | | | SB_EC_C2ONB239V4 | C2ONB239V4 | | | SB_EC_C2ONB239V5 | C2ONB239V5 | | | SB_EC_C2PNB272W1 | C2PNB272W1 | | | SB_EC_C2PNB304W1 | C2PNB304W1 | | | SB_EC_C2TNB359V1 | C2TNB359V1 | | | SB_EC_C2PNB368W1 | C2PNB368W1 | | | SB_EC_C2TNB431R1 | C2TNB431R1 | | | SB_EC_NISTP192 | NISTP192 | | | SB_EC_NISTP224 | NISTP224 | | | SB_EC_NISTP256 | NISTP256 | | | SB_EC_NISTP384 | NISTP384 | | | SB_EC_NISTP521 | NISTP521 | | | SB_EC_NISTB163 | NISTB163 | | | SB_EC_NISTB233 | NISTB233 | | | SB_EC_NISTB283 | NISTB283 | | | SB_EC_NISTB409 | NISTB409 | | | SB_EC_NISTB571 | NISTB571 | | | SB_EC_NISTK163 | NISTK163 | | | SB_EC_NISTK233 | NISTK233 | | | SB_EC_NISTK283 | NISTK283 | | | SB_EC_NISTK409 | NISTK409 | | | SB_EC_NISTK571 | NISTK571 | | | SB_EC_GOSTCPTEST | GOSTCPTEST | | | SB_EC_GOSTCPA | GOSTCPA | | | SB_EC_GOSTCPB | GOSTCPB | | | SB_EC_GOSTCPC | GOSTCPC | | | SB_EC_GOSTCPXCHA | GOSTCPXCHA | | | SB_EC_GOSTCPXCHB | GOSTCPXCHB | | | SB_EC_BRAINPOOLP160R1 | BRAINPOOLP160R1 | | | SB_EC_BRAINPOOLP160T1 | BRAINPOOLP160T1 | | | SB_EC_BRAINPOOLP192R1 | BRAINPOOLP192R1 | | | SB_EC_BRAINPOOLP192T1 | BRAINPOOLP192T1 | | | SB_EC_BRAINPOOLP224R1 | BRAINPOOLP224R1 | | | SB_EC_BRAINPOOLP224T1 | BRAINPOOLP224T1 | | | SB_EC_BRAINPOOLP256R1 | BRAINPOOLP256R1 | | | SB_EC_BRAINPOOLP256T1 | BRAINPOOLP256T1 | | | SB_EC_BRAINPOOLP320R1 | BRAINPOOLP320R1 | | | SB_EC_BRAINPOOLP320T1 | BRAINPOOLP320T1 | | | SB_EC_BRAINPOOLP384R1 | BRAINPOOLP384R1 | | | SB_EC_BRAINPOOLP384T1 | BRAINPOOLP384T1 | | | SB_EC_BRAINPOOLP512R1 | BRAINPOOLP512R1 | | | SB_EC_BRAINPOOLP512T1 | BRAINPOOLP512T1 | | | SB_EC_CURVE25519 | CURVE25519 | | | SB_EC_CURVE448 | CURVE448 | | **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. ```text 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](#Certificate_f_SigAlgorithm) to find out the hash algorithm that is part of the certificate signature. | | | | | --- | --- | --- | | SB_HASH_ALGORITHM_SHA1 | SHA1 | | | SB_HASH_ALGORITHM_SHA224 | SHA224 | | | SB_HASH_ALGORITHM_SHA256 | SHA256 | | | SB_HASH_ALGORITHM_SHA384 | SHA384 | | | SB_HASH_ALGORITHM_SHA512 | SHA512 | | | SB_HASH_ALGORITHM_MD2 | MD2 | | | SB_HASH_ALGORITHM_MD4 | MD4 | | | SB_HASH_ALGORITHM_MD5 | MD5 | | | SB_HASH_ALGORITHM_RIPEMD160 | RIPEMD160 | | | SB_HASH_ALGORITHM_CRC32 | CRC32 | | | SB_HASH_ALGORITHM_SSL3 | SSL3 | | | SB_HASH_ALGORITHM_GOST_R3411_1994 | GOST1994 | | | SB_HASH_ALGORITHM_WHIRLPOOL | WHIRLPOOL | | | SB_HASH_ALGORITHM_POLY1305 | POLY1305 | | | SB_HASH_ALGORITHM_SHA3_224 | SHA3_224 | | | SB_HASH_ALGORITHM_SHA3_256 | SHA3_256 | | | SB_HASH_ALGORITHM_SHA3_384 | SHA3_384 | | | SB_HASH_ALGORITHM_SHA3_512 | SHA3_512 | | | SB_HASH_ALGORITHM_BLAKE2S_128 | BLAKE2S_128 | | | SB_HASH_ALGORITHM_BLAKE2S_160 | BLAKE2S_160 | | | SB_HASH_ALGORITHM_BLAKE2S_224 | BLAKE2S_224 | | | SB_HASH_ALGORITHM_BLAKE2S_256 | BLAKE2S_256 | | | SB_HASH_ALGORITHM_BLAKE2B_160 | BLAKE2B_160 | | | SB_HASH_ALGORITHM_BLAKE2B_256 | BLAKE2B_256 | | | SB_HASH_ALGORITHM_BLAKE2B_384 | BLAKE2B_384 | | | SB_HASH_ALGORITHM_BLAKE2B_512 | BLAKE2B_512 | | | SB_HASH_ALGORITHM_SHAKE_128 | SHAKE_128 | | | SB_HASH_ALGORITHM_SHAKE_256 | SHAKE_256 | | | SB_HASH_ALGORITHM_SHAKE_128_LEN | SHAKE_128_LEN | | | SB_HASH_ALGORITHM_SHAKE_256_LEN | SHAKE_256_LEN | | **Issuer** *char* (read-only)* *Default Value: ""* The common name of the certificate issuer (CA), typically a company name.

[Curve](#Certificate_f_Curve), and [PublicKeyBytes](#Certificate_f_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](#Certificate_f_PublicKeyBytes) or [PrivateKeyBytes](#Certificate_f_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](#Certificate_f_Fingerprint) field. The key fingerprint 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](CertificateManager.md#CertificateManager_m_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](#Certificate_f_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](#Certificate_f_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](#Certificate_f_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](#Certificate_f_SubjectKeyID) and [CAKeyID](#Certificate_f_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 ```text 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: - [AsyncDocumentID](#ExternalCrypto_f_AsyncDocumentID) - [CustomParams](#ExternalCrypto_f_CustomParams) - [Data](#ExternalCrypto_f_Data) - [ExternalHashCalculation](#ExternalCrypto_f_ExternalHashCalculation) - [HashAlgorithm](#ExternalCrypto_f_HashAlgorithm) - [KeyID](#ExternalCrypto_f_KeyID) - [KeySecret](#ExternalCrypto_f_KeySecret) - [Method](#ExternalCrypto_f_Method) - [Mode](#ExternalCrypto_f_Mode) - [PublicKeyAlgorithm](#ExternalCrypto_f_PublicKeyAlgorithm) ## 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_SHA1 | SHA1 | | | SB_HASH_ALGORITHM_SHA224 | SHA224 | | | SB_HASH_ALGORITHM_SHA256 | SHA256 | | | SB_HASH_ALGORITHM_SHA384 | SHA384 | | | SB_HASH_ALGORITHM_SHA512 | SHA512 | | | SB_HASH_ALGORITHM_MD2 | MD2 | | | SB_HASH_ALGORITHM_MD4 | MD4 | | | SB_HASH_ALGORITHM_MD5 | MD5 | | | SB_HASH_ALGORITHM_RIPEMD160 | RIPEMD160 | | | SB_HASH_ALGORITHM_CRC32 | CRC32 | | | SB_HASH_ALGORITHM_SSL3 | SSL3 | | | SB_HASH_ALGORITHM_GOST_R3411_1994 | GOST1994 | | | SB_HASH_ALGORITHM_WHIRLPOOL | WHIRLPOOL | | | SB_HASH_ALGORITHM_POLY1305 | POLY1305 | | | SB_HASH_ALGORITHM_SHA3_224 | SHA3_224 | | | SB_HASH_ALGORITHM_SHA3_256 | SHA3_256 | | | SB_HASH_ALGORITHM_SHA3_384 | SHA3_384 | | | SB_HASH_ALGORITHM_SHA3_512 | SHA3_512 | | | SB_HASH_ALGORITHM_BLAKE2S_128 | BLAKE2S_128 | | | SB_HASH_ALGORITHM_BLAKE2S_160 | BLAKE2S_160 | | | SB_HASH_ALGORITHM_BLAKE2S_224 | BLAKE2S_224 | | | SB_HASH_ALGORITHM_BLAKE2S_256 | BLAKE2S_256 | | | SB_HASH_ALGORITHM_BLAKE2B_160 | BLAKE2B_160 | | | SB_HASH_ALGORITHM_BLAKE2B_256 | BLAKE2B_256 | | | SB_HASH_ALGORITHM_BLAKE2B_384 | BLAKE2B_384 | | | SB_HASH_ALGORITHM_BLAKE2B_512 | BLAKE2B_512 | | | SB_HASH_ALGORITHM_SHAKE_128 | SHAKE_128 | | | SB_HASH_ALGORITHM_SHAKE_256 | SHAKE_256 | | | SB_HASH_ALGORITHM_SHAKE_128_LEN | SHAKE_128_LEN | | | SB_HASH_ALGORITHM_SHAKE_256_LEN | SHAKE_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](#ExternalCrypto_f_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: ```text 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](#ExternalCrypto_f_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. | | | | | --- | --- | --- | | SB_CERT_ALGORITHM_ID_RSA_ENCRYPTION | rsaEncryption | | | SB_CERT_ALGORITHM_MD2_RSA_ENCRYPTION |

field values. # MailAddress Type A container for an e-mail addressee. ## Syntax *SecureBlackboxMailAddress* (declared in *secureblackbox.h*) ## Remarks This object is a container for an e-mail identity record. A typical e-mail address consists of an RFC822 e-mail address (john@doe.com), a friendly name (John Doe), and a group name (Officers). The following fields are available: - [Address](#MailAddress_f_Address) - [DisplayName](#MailAddress_f_DisplayName) - [GroupName](#MailAddress_f_GroupName) ## Fields **Address** *char** *Default Value: ""* Contains the e-mail address in the form of john@doe.com. **DisplayName** *char** *Default Value: ""* Contains the friendly name of the user of this address, such as John Doe. **GroupName** *char** *Default Value: ""* The name of the group this address belongs to. ## Constructors ```text MailAddress(const char* lpszAddress) ``` Creates a new e-mail address object. ```text MailAddress(const char* lpszDisplayName, const char* lpszAddress) ``` Creates a new e-mail address object from an address and a display name. # MailAttachment Type Represents an attachment to an e-mail message. ## Syntax *SecureBlackboxMailAttachment* (declared in *secureblackbox.h*) ## Remarks This object is a container for message attachments. The following fields are available: - [ContentSubtype](#MailAttachment_f_ContentSubtype) - [ContentType](#MailAttachment_f_ContentType) - [CreationDate](#MailAttachment_f_CreationDate) - [Data](#MailAttachment_f_Data) - [Description](#MailAttachment_f_Description) - [FileName](#MailAttachment_f_FileName) - [Handle](#MailAttachment_f_Handle) - [ID](#MailAttachment_f_ID) - [ModificationDate](#MailAttachment_f_ModificationDate) - [ReadDate](#MailAttachment_f_ReadDate) - [Size](#MailAttachment_f_Size) ## Fields **ContentSubtype** *char** *Default Value: ""* Contains the content subtype of the attachment. **ContentType** *char** *Default Value: ""* Contains the content type of the attachment. **CreationDate** *char** *Default Value: ""* The creation date. **Data** *char** *Default Value: * The content of the attachment. **Description** *char** *Default Value: ""* Textual description of the attachment. This property maps to the Content-Description e-mail header field. Although the field is optional, the ability to associate descriptive information with a given body is often desirable. One example is specifying the title of an image using this property. **FileName** *char** *Default Value: ""* Specifies the name of the attachment file. **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. ```text pdfSigner.setSigningCertHandle(certMgr.getCertHandle()); ``` **ID** *char** *Default Value: ""* Contains the attachment's unique identifier. **ModificationDate** *char** *Default Value: ""* Specifies the date and time of the file's last modification. **ReadDate** *char** *Default Value: ""* Specifies the file's last read date. **Size** *int64* *Default Value: 0* The attachment's size in bytes. ## Constructors ```text MailAttachment(const char* lpszContentType) ``` Creates an empty mail attachment object. # MailMessage Type Represents an e-mail message. ## Syntax *SecureBlackboxMailMessage* (declared in *secureblackbox.h*) ## Remarks This object is a container for an e-mail message. A message consists of a header and a body. The header, in turn, consists of several header fields. The names, syntax, and expected contents of the header fields are standardized. The message body can contain anything you like (a message may not even have a body at all). The following fields are available: - [AttachmentCount](#MailMessage_f_AttachmentCount) - [Bcc](#MailMessage_f_Bcc) - [Cc](#MailMessage_f_Cc) - [Comments](#MailMessage_f_Comments) - [Date](#MailMessage_f_Date) - [DeliveryReceipt](#MailMessage_f_DeliveryReceipt) - [From](#MailMessage_f_From) - [Handle](#MailMessage_f_Handle) - [HtmlText](#MailMessage_f_HtmlText) - [ID](#MailMessage_f_ID) - [InReplyTo](#MailMessage_f_InReplyTo) - [Keywords](#MailMessage_f_Keywords) - [Mailer](#MailMessage_f_Mailer) - [PlainText](#MailMessage_f_PlainText) - [Priority](#MailMessage_f_Priority) - [ReadReceipt](#MailMessage_f_ReadReceipt) - [References](#MailMessage_f_References) - [ReplyTo](#MailMessage_f_ReplyTo) - [ReturnPath](#MailMessage_f_ReturnPath) - [Sender](#MailMessage_f_Sender) - [SendTo](#MailMessage_f_SendTo) - [Subject](#MailMessage_f_Subject) ## Fields **AttachmentCount** *int (read-only)* *Default Value: 0* Returns the number of attachments in this message. **Bcc** *char** *Default Value: ""* The contents of the BCC header field. The BCC header field contains the addresses of secondary recipients of the message whose addresses are not to be revealed to other recipients of the message. Mail servers remove the BCC header when processing the message and use its value for dispatching the message only. **Cc** *char** *Default Value: ""* The value of the CC header field. The CC field contains the addresses of secondary recipients of the message. **Comments** *char** *Default Value: ""* Contains additional information about the message body. **Date** *char** *Default Value: ""* The date and time when the message entered the mail delivery system. This field contains the date and time at which the creator of the message posted the message to the mail delivery system. The date is returned and accepted in UTC time zone. **DeliveryReceipt** *int* *Default Value: FALSE* Enables delivery notification. **From** *char** *Default Value: ""* Contains the value of the From header field. This field contains the address(es) of the message author(s). If the actual sender is not the author of the message, use [Sender](#MailMessage_f_Sender) to specify the sender separately. **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. ```text pdfSigner.setSigningCertHandle(certMgr.getCertHandle()); ``` **HtmlText** *char** *Default Value: ""* The HTML version of the message. **ID** *char** *Default Value: ""* The contents of the Message-ID header field. This field contains a unique identifier that refers to a particular version of this message. **InReplyTo** *char** *Default Value: ""* The value of the In-Reply-To header field. A reply message should have the "In-Reply-To:" header field which may be used to identify the message (or messages) to which the new message is a reply. **Keywords** *char** *Default Value: ""* The value of the Keywords header field. This field can be used to add some important words and phrases that might be useful for the recipient. **Mailer** *char* (read-only)* *Default Value: ""* The name of the software that was used to send the message. **PlainText** *char** *Default Value: ""* The plain text version of the message. **Priority** *int* *Default Value: 2* Specifies the message priority.

A reply message should include a "References:" header field which may be used to identify the "conversation thread". If the initial message is a reply itself, the References of the reply contain combined content of its "References:", "InReplyTo:" and "MessageID:" fields, subject to their presence in the original message. **ReplyTo** *char** *Default Value: ""* The value of the Reply-To header field. This field contains the addresses to which the replies to this message should be sent. This field is optional. If not specified, the replies must be sent to the addresses specified in the [From](#MailMessage_f_From) field. **ReturnPath** *char** *Default Value: ""* The value of the Return-Path header field. This field contains the address to which this message shall be returned in case of unsuccessful delivery. **Sender** *char** *Default Value: ""* The value of the Sender header field. This field specifies the mailbox of the agent responsible for the actual transmission of this message. If the originator of the message can be indicated by a single mailbox and both the author and the transmitter are identical, the "Sender:" field is deemed excessive and should not be used. **SendTo** *char** *Default Value: ""* The value of the To header field. This field specifies the address(es) of the primary recipient(s) of the message. **Subject** *char** *Default Value: ""* Contains the subject field of this message. ## Constructors ```text MailMessage() ``` Creates a new empty mail message object. # MailSecuritySettings Type Provides access to the new message security settings. ## Syntax *SecureBlackboxMailSecuritySettings* (declared in *secureblackbox.h*) ## Remarks Use this object to tune up the security setting for the created message.

The following fields are available: - [Category](#StringNameValuePair_f_Category) - [Format](#StringNameValuePair_f_Format) - [Name](#StringNameValuePair_f_Name) - [Value](#StringNameValuePair_f_Value) ## Fields **Category** *char** *Default Value: ""* Specifies the string category of the contained value. This property allows to check or set the category (or type) associated with the contained value. Depending on the format used to load or save the string, the category parameter may or may not be used. For example, for ASN.1 property lists the category contains the ASN.1 tag of the contained data (OCTETSTRING, UTF8STRING, INTEGER, ...). For basic (name, value) pairs, such as HTTP headers, the category parameter is not used. **Format** *int* *Default Value: 0* Specifies the format (encoding) of the value contained in the [Value](#StringNameValuePair_f_Value) property. Use this property to check or set the format of the contained value. Remember to provide the actual value in the appropriate format that matches this setting: ```text utils.NameValuePairs[0].Name = "key"; utils.NameValuePairs[0].Format = svfBinary; utils.NameValuePairs[0].Name = "0a1b2c3d4e5f6071"; ``` The following formats are currently supported: | | | | | --- | --- | --- | | svfText | 0 | The property contains text | | svfBinary | 1 | The property contains binary data. The Value property contains a hex encoding of it. | **Name** *char** *Default Value: ""* The name element in a (name, value) pair. **Value** *char** *Default Value: ""* The value element in a (name, value) pair. ## Constructors ```text StringNameValuePair(const char* lpszName, const char* lpszValue) ``` Creates a name-value pair from a name and a value. ```text StringNameValuePair() ``` Creates an empty name-value object. # SecureBlackboxList Type ## Syntax *SecureBlackboxList* (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. ```text int GetCount() {} ``` ```text int SetCount(int count) {} ``` ```text T* Get(int index) {} ``` ```text T* Set(int index, T* value) {} ``` | | | | --- | --- | | Methods | | | GetCount | This method returns the current size of the collection. | | 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. | | 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. | | 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. | # 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. ```text bool CanRead() { return true; } ``` ```text bool CanSeek() { return true; } ``` ```text bool CanWrite() { return true; } ``` ```text int64 GetLength() = 0; ``` ```text void Close() {} ``` ```text int Flush() { return 0; } ``` ```text int Read(void* buffer, int count) = 0; ``` ```text int64 Seek(int64 offset, int seekOrigin) = 0; ``` ```text int Write(const void* buffer, int count) = 0; ``` | | | | --- | --- | | Properties | | | CanRead | Whether the stream supports reading. | | CanSeek | Whether the stream supports seeking. | | CanWrite | Whether the stream supports writing. | | Length | Gets the length of the stream, in bytes. | | Methods | | | Close | Closes the stream, releasing all resources currently allocated for it. 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. 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. 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. 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. 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](#mailwriter-class) 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](#config-method-mailwriter-class) 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. This setting is supported only in the Java edition for all applicable signing components except [PDFSigner](PDFSigner.md#PDFSigner), where this limitation does not apply. ### 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: | | | | | --- | --- | --- | | off | | No caching (default) | | local | | Local caching | | global | | Global 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. **EnableSSHMLKEM**: Enables support for ML-KEM/hybrid key exchange algorithms in SSH client and server components.Use this setting to enable hybrid key exchange algorithms in client and server SSH and SFTP components. This is a global setting that enables ML-KEM blanketly in all SSH-dependent components. **EnableTLSMLKEM**: Enables support for ML-KEM and hybrid groups in TLS client and server components.Use this setting to enable ML-KEM and hybrid key exchange groups in client and server TLS components. This is a global setting that enables ML-KEM blanketly in all TLS-dependent components. **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. Supported Values: | | | | --- | --- | | auto | Use hardware cryptography if available; otherwise, fall back to software-based cryptography (default). | | enable | Always attempt to use hardware cryptography.

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. **LogDestination**: Specifies the debug log destination.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) | **LogDetails**: Specifies the debug log details to dump.Contains a comma-separated list of values that specifies which debug log details to dump.

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) | **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. **PKICache**: Specifies which PKI elements (certificates, CRLs, OCSP responses) should be cached.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): ```text PKICache=certificate,crl,ocsp ``` In this example, the component caches certificates, CRLs, and OCSP responses. **PKICachePath**: Specifies the file system path where cached PKI data is stored.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: ```text PKICachePath=C:\Temp\cache ``` In this example, the cached PKI data is stored in the C:\Temp\cache directory. **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: | | | | | --- | --- | --- | | none | | No static DNS rules (default) | | local | | Local static DNS rules | | global | | Global 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 divided 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 cached 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. Syntax: ```text 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: ```text Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER"); ``` Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS: ```text Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS"); ``` **XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.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. **XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.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). **XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing.
