# MailReader Component

The MailReader component implements parsing and decryption of e-mail messages.

## Syntax

```text
TsbxMailReader
```

## Remarks

MailReader parses and decrypts e-mail messages, as well as verifies electronic signatures.

Loading a e-mail message and accessing its properties:

```text
  MailReader reader = new MailReader();
  reader.LoadFromFile("path\\message.eml");
  Console.WriteLine($"From: {reader.Message.From}");
  Console.WriteLine($"To  : {reader.Message.SendTo}");
  Console.WriteLine($"Subject: {reader.Message.Subject}");
  Console.WriteLine($"Attachments: {reader.Message.AttachmentCount}");
  Console.WriteLine("Plain text:");
  Console.WriteLine(reader.Message.PlainText);
```

Checking a signed message and validating its signature:

```text
  MailReader reader = new MailReader();
  reader.LoadFromFile("path\\message.eml");
  if (reader.SecurityInfo.Signed)
  {
    if (reader.SecurityInfo.SignatureValidationResult == SignatureValidities.svtValid)
      Console.WriteLine($"Signed by {reader.SigningCertificate.Subject} and the signature is valid");
    else
      Console.WriteLine("Signature is NOT valid");
  }
```

Processing an encrypted e-mail message:

```text
  MailReader reader = new MailReader();
  reader.OnDecryptionInfoNeeded += (s, e) =>
  {
    // here you should provide a certificate for decryption;
    // use the provided IssuerRDN and SerialNumber/SubjectKeyID
    // values to find an appropriate certificate, then
    // assign the certificate to DecryptionCertificate property;
    // the certificate should include its private key
  };
  reader.LoadFromFile("path\\message.eml");
```

__property String CcAddrGroupName[int CcAddrIndex] = { read=FCcAddrGroupName };
```

## Default Value

""

## Remarks

The name of the group this address belongs to.

The *CcAddrIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CcAddrCount](#ccaddrcount-property-mailreader-component) property.

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

## Data Type

String

# DecryptionCertBytes Property ([MailReader](#mailreader-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray DecryptionCertBytes = { read=FDecryptionCertBytes };
```

## Remarks

Returns the raw certificate data in DER format.

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

## Data Type

Byte Array

# DecryptionCertCA Property ([MailReader](#mailreader-component) Component)

Indicates whether the certificate has a CA capability.

## Syntax

*C++ Builder Syntax*

```text
__property bool DecryptionCertCA = { read=FDecryptionCertCA, write=FSetDecryptionCertCA };
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

This property is not available at design time.

## Data Type

Boolean

# DecryptionCertCAKeyID Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray DecryptionCertCAKeyID = { read=FDecryptionCertCAKeyID };
```

## Remarks

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

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [DecryptionCertSubjectKeyID](#decryptioncertsubjectkeyid-property-mailreader-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

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

## Data Type

Byte Array

# DecryptionCertCertType Property ([MailReader](#mailreader-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxMailReaderDecryptionCertCertTypes DecryptionCertCertType = { read=FDecryptionCertCertType };
enum TsbxMailReaderDecryptionCertCertTypes {
  ctUnknown=0,
  ctX509Certificate=1,
  ctX509CertificateRequest=2
};
```

## Default Value

ctUnknown

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_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](#CertificateManager) component to load or create new certificate and certificate requests objects.

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

## Data Type

Integer

# DecryptionCertCRLDistributionPoints Property ([MailReader](#mailreader-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*C++ Builder Syntax*

```text
__property String DecryptionCertCRLDistributionPoints = { read=FDecryptionCertCRLDistributionPoints, write=FSetDecryptionCertCRLDistributionPoints };
```

## Default Value

""

## Remarks

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

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

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

This property is not available at design time.

## Data Type

String

# DecryptionCertCurve Property ([MailReader](#mailreader-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*C++ Builder Syntax*

```text
__property String DecryptionCertCurve = { read=FDecryptionCertCurve, write=FSetDecryptionCertCurve };
```

## Default Value

""

## Remarks

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

## Data Type

String

# DecryptionCertFingerprint Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String DecryptionCertFingerprint = { read=FDecryptionCertFingerprint };
```

## Default Value

""

## Remarks

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.

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

## Data Type

String

# DecryptionCertFriendlyName Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String DecryptionCertFriendlyName = { read=FDecryptionCertFriendlyName };
```

## Default Value

""

## Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

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

## Data Type

String

# DecryptionCertHandle Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property __int64 DecryptionCertHandle = { read=FDecryptionCertHandle, write=FSetDecryptionCertHandle };
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

This property is not available at design time.

## Data Type

Long64

# DecryptionCertHashAlgorithm Property ([MailReader](#mailreader-component) Component)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Syntax

*C++ Builder Syntax*

```text
__property String DecryptionCertHashAlgorithm = { read=FDecryptionCertHashAlgorithm, write=FSetDecryptionCertHashAlgorithm };
```

## Default Value

""

## Remarks

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 [DecryptionCertSigAlgorithm](#decryptioncertsigalgorithm-property-mailreader-component) to find out the hash algorithm that is part of the certificate signature.

This property is not available at design time.

## Data Type

String

# DecryptionCertKeyBits Property ([MailReader](#mailreader-component) Component)

Returns the length of the public key in bits.

## Syntax

*C++ Builder Syntax*

```text
__property int DecryptionCertKeyBits = { read=FDecryptionCertKeyBits };
```

## Default Value

0

## Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the [DecryptionCertPublicKeyBytes](#decryptioncertpublickeybytes-property-mailreader-component) or [DecryptionCertPrivateKeyBytes](#decryptioncertprivatekeybytes-property-mailreader-component) property would typically contain auxiliary values, and therefore be longer.

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

## Data Type

This property is independent from [DecryptionCertPrivateKeyBytes](#decryptioncertprivatekeybytes-property-mailreader-component), and can be set to *True* even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

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

## Data Type

Boolean

# DecryptionCertPrivateKeyExtractable Property ([MailReader](#mailreader-component) Component)

Indicates whether the private key is extractable (exportable).

## Syntax

*C++ Builder Syntax*

```text

# ExternalCryptoKeyID Property ([MailReader](#mailreader-component) Component)

The ID of the pre-shared key used for DC request authentication.

## Syntax

*C++ Builder Syntax*

```text
__property String ExternalCryptoKeyID = { read=FExternalCryptoKeyID, write=FSetExternalCryptoKeyID };
```

## Default Value

""

## Remarks

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 [ExternalCryptoKeySecret](#externalcryptokeysecret-property-mailreader-component) 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";
```

## Data Type

String

# ExternalCryptoKeySecret Property ([MailReader](#mailreader-component) Component)

  crcAllCRLAndOCSP=4,
  crcAnyCRL=5,
  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};
```

## Default Value

crcAuto

## Remarks

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

## Data Type

Boolean

# SigningCertCAKeyID Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray SigningCertCAKeyID = { read=FSigningCertCAKeyID };
```

## Remarks

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

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [SigningCertSubjectKeyID](#signingcertsubjectkeyid-property-mailreader-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

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

## Data Type

Byte Array

# SigningCertCRLDistributionPoints Property ([MailReader](#mailreader-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*C++ Builder Syntax*

```text
__property String SigningCertCRLDistributionPoints = { read=FSigningCertCRLDistributionPoints };
```

## Default Value

""

## Remarks

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

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

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

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

## Data Type

String

# SigningCertCurve Property ([MailReader](#mailreader-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*C++ Builder Syntax*

## Data Type

String

# SigningCertFingerprint Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String SigningCertFingerprint = { read=FSigningCertFingerprint };
```

## Default Value

""

## Remarks

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.

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

## Data Type

String

# SigningCertFriendlyName Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String SigningCertFriendlyName = { read=FSigningCertFriendlyName };
```

## Default Value

""

## Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

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

## Data Type

String

# SigningCertHandle Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property __int64 SigningCertHandle = { read=FSigningCertHandle };
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

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

## Data Type

Long64

# SigningCertHashAlgorithm Property ([MailReader](#mailreader-component) Component)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Syntax

*C++ Builder Syntax*

```text
__property String SigningCertHashAlgorithm = { read=FSigningCertHashAlgorithm };
```

## Default Value

""

## Remarks

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 [SigningCertSigAlgorithm](#signingcertsigalgorithm-property-mailreader-component) to find out the hash algorithm that is part of the certificate signature.

# TLSRevocationCheck Property ([MailReader](#mailreader-component) Component)

Specifies the kind(s) of revocation check to perform.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxMailReaderTLSRevocationChecks TLSRevocationCheck = { read=FTLSRevocationCheck, write=FSetTLSRevocationCheck };
enum TsbxMailReaderTLSRevocationChecks {
  crcNone=0,

  crcAllCRLAndOCSP=4,
  crcAnyCRL=5,
  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};
```

## Default Value

crcAuto

## Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

This property is not available at design time.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

Byte Array

# UsedCertCA Property ([MailReader](#mailreader-component) Component)

Indicates whether the certificate has a CA capability.

## Syntax

*C++ Builder Syntax*

```text
__property bool UsedCertCA[int UsedCertIndex] = { read=FUsedCertCA };
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

Boolean

# UsedCertCAKeyID Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray UsedCertCAKeyID[int UsedCertIndex] = { read=FUsedCertCAKeyID };
```

## Remarks

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

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [UsedCertSubjectKeyID](#usedcertsubjectkeyid-property-mailreader-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

Byte Array

# UsedCertCertType Property ([MailReader](#mailreader-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxMailReaderUsedCertCertTypes UsedCertCertType[int UsedCertIndex] = { read=FUsedCertCertType };
enum TsbxMailReaderUsedCertCertTypes {
  ctUnknown=0,
  ctX509Certificate=1,
  ctX509CertificateRequest=2
};
```

## Default Value

ctUnknown

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_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](#CertificateManager) component to load or create new certificate and certificate requests objects.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

Integer

# UsedCertCRLDistributionPoints Property ([MailReader](#mailreader-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*C++ Builder Syntax*

```text
__property String UsedCertCRLDistributionPoints[int UsedCertIndex] = { read=FUsedCertCRLDistributionPoints };
```

## Default Value

""

## Remarks

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

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

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

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

String

# UsedCertCurve Property ([MailReader](#mailreader-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*C++ Builder Syntax*

```text
__property String UsedCertCurve[int UsedCertIndex] = { read=FUsedCertCurve };
```

## Default Value

""

## Remarks

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

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

String

# UsedCertFingerprint Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String UsedCertFingerprint[int UsedCertIndex] = { read=FUsedCertFingerprint };
```

## Default Value

""

## Remarks

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.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

String

# UsedCertFriendlyName Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property String UsedCertFriendlyName[int UsedCertIndex] = { read=FUsedCertFriendlyName };
```

## Default Value

""

## Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

String

# UsedCertHandle Property ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
__property __int64 UsedCertHandle[int UsedCertIndex] = { read=FUsedCertHandle };
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-mailreader-component) property.

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

## Data Type

Long64

# UsedCertHashAlgorithm Property ([MailReader](#mailreader-component) Component)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Syntax

*C++ Builder Syntax*

```text
__property String UsedCertHashAlgorithm[int UsedCertIndex] = { read=FUsedCertHashAlgorithm };
```

## Default Value

""

## Remarks

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 [UsedCertSigAlgorithm](#usedcertsigalgorithm-property-mailreader-component) to find out the hash algorithm that is part of the certificate signature.

Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either the signature creation time or the current time).

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

## Data Type

String

# Config Method ([MailReader](#mailreader-component) Component)

Sets or retrieves a configuration setting.

## Syntax

*C++ Builder Syntax*

```text
String __fastcall Config(String ConfigurationString);
```

## Remarks

Config is a generic method available in every component. It is used to set and retrieve [configuration settings](#config-settings-mailreader-component) for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-mailreader-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# DoAction Method ([MailReader](#mailreader-component) Component)

Performs an additional action.

## Syntax

*C++ Builder Syntax*

```text
String __fastcall DoAction(String ActionID, String ActionParams);
```

## Remarks

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

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

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

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |

# DecryptionInfoNeeded Event ([MailReader](#mailreader-component) Component)

Asks the application to provide a decryption certificate.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
} TsbxMailReaderDecryptionInfoNeededEventParams;
typedef void __fastcall (__closure *TsbxMailReaderDecryptionInfoNeededEvent)(System::TObject* Sender, TsbxMailReaderDecryptionInfoNeededEventParams *e);
__property TsbxMailReaderDecryptionInfoNeededEvent OnDecryptionInfoNeeded = { read=FOnDecryptionInfoNeeded, write=FOnDecryptionInfoNeeded };
```

## Remarks

This event is fired when the component needs a decryption certificate. Use the provided values to look up the certificate, and assign it to DecryptionCertificate property.

Note that the decryption certificate must have an associated private key.

# Error Event ([MailReader](#mailreader-component) Component)

Reports information about errors during e-mail message loading, parsing or saving.

## Syntax

*C++ Builder Syntax*

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

## Remarks

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

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

# ExternalDecrypt Event ([MailReader](#mailreader-component) Component)

Handles remote or external decryption.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String OperationId;
  String Algorithm;
  String Pars;
  String EncryptedData;
  String Data;
} TsbxMailReaderExternalDecryptEventParams;
typedef void __fastcall (__closure *TsbxMailReaderExternalDecryptEvent)(System::TObject* Sender, TsbxMailReaderExternalDecryptEventParams *e);
__property TsbxMailReaderExternalDecryptEvent OnExternalDecrypt = { read=FOnExternalDecrypt, write=FOnExternalDecrypt };
```

## Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the *EncryptedData* parameter, and is expected to decrypt it and place the decrypted value into the *Data* parameter.

*OperationId* provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. *Algorithm* specifies the encryption algorithm being used, and *Pars* contains algorithm-dependent parameters.

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

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

# Notification Event ([MailReader](#mailreader-component) Component)

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

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String EventID;
  String EventParam;
} TsbxMailReaderNotificationEventParams;
typedef void __fastcall (__closure *TsbxMailReaderNotificationEvent)(System::TObject* Sender, TsbxMailReaderNotificationEventParams *e);
__property TsbxMailReaderNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };
```

## Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the *EventID* parameter. *EventParam* contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

# SignatureFound Event ([MailReader](#mailreader-component) Component)

Signifies the start of signature validation.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  bool CertFound;
  bool ValidateSignature;
  bool ValidateChain;
} TsbxMailReaderSignatureFoundEventParams;
typedef void __fastcall (__closure *TsbxMailReaderSignatureFoundEvent)(System::TObject* Sender, TsbxMailReaderSignatureFoundEventParams *e);
__property TsbxMailReaderSignatureFoundEvent OnSignatureFound = { read=FOnSignatureFound, write=FOnSignatureFound };
```

## Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters. It fires for every signature located in the verified document or message.

The *CertFound* parameter is set to True if the component has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the  and  properties respectively.

Use the *ValidateSignature* and *ValidateChain* parameters to tell the verifier which stages to include in the validation.

# SignatureValidated Event ([MailReader](#mailreader-component) Component)

Marks the completion of the signature validation routine.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  int ValidationResult;
} TsbxMailReaderSignatureValidatedEventParams;
typedef void __fastcall (__closure *TsbxMailReaderSignatureValidatedEvent)(System::TObject* Sender, TsbxMailReaderSignatureValidatedEventParams *e);
__property TsbxMailReaderSignatureValidatedEvent OnSignatureValidated = { read=FOnSignatureValidated, write=FOnSignatureValidated };
```

## Remarks

This event is fired upon the completion of the signature validation routine, and reports the respective validation result.

Use the *IssuerRDN*, *SerialNumber*, and/or *SubjectKeyID* parameters to identify the signing certificate.

*ValidationResult* is set to 0 if the validation has been successful, or to a non-zero value in case of a validation failure.

|  |  |  |
| --- | --- | --- |
| svtValid | 0 | The signature is valid |
| svtUnknown | 1 | Signature validity is unknown |
| svtCorrupted | 2 | The signature is corrupted |
| svtSignerNotFound | 3 | Failed to acquire the signing certificate. The signature cannot be validated. |
| svtFailure | 4 | General failure |
| svtReferenceCorrupted | 5 | Reference corrupted (XML-based signatures only) |

# Config Settings ([MailReader](#mailreader-component) Component)

 The component accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these *internal properties* is provided through the [Config](#config-method-mailreader-component) method.

### MailReader Config Settings

**ChainCurrentCACert**: Returns the current CA certificate.This property returns the CA certificate that is used on the current step.

**ChainCurrentCert**: Returns the certificate that is currently being validated.Use this property to obtain the body of the certificate that is currently being validated.

**ChainCurrentCRL**: Returns the current CRL.Returns the CRL object that is currently being processed.

**ChainCurrentCRLSize**: Returns the size of the current CRL.This property returns the size of the CRL object that is currently being processed.

**ChainCurrentOCSP**: Returns the current OCSP response.Returns the OCSP object that is currently being processed.

**ChainCurrentOCSPSigner**: Returns the signer of the current OCSP object.Returns the signer/CA that has issued the OCSP response that is currently being processed.

**ChainInterimDetails**: Returns the current interim validation details.This property returns the interim chain validation details.

**ChainInterimResult**: Returns the current interim validation result.Use this setting to obtain the current (mid-chain) validation result. This property applies to the current validation step and may change as the chain walk proceeds. The final result will be published in the ChainValidationResult property once the validation process completes.

**CheckValidityPeriodForTrusted**: Whether to check validity period for trusted certificates.Whether to check validity period for trusted certificates.

**DislikeOpenEndedOCSPs**: Tells the component to discourage OCSP responses without an explicit NextUpdate parameter.When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the component is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022).

**EvaluateSystemTrust**: Enables or disables usage of the platform's built-in trust validation facilities.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is disabled by default, because enabling it may prevent the AdES components from collecting full revocation information required for long-term validation (LTV) signatures.

**EvaluateSystemTrustForSelfSignedCertificates**: Enables or disables usage of the platform's built-in trust validation facilities for self-signed certificates.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) for self-signed certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**EvaluateSystemTrustForSSL**: Enables or disables usage of the platform's built-in trust validation facilities for SSL/TLS.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) specifically for SSL/TLS certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**ForceCompleteChainValidation**: Whether to check the CA certificates when the signing certificate is invalid.Set this property to True to check issuer (CA) certificates if the signing or an intermediate chain certificate is invalid.

**ForceCompleteChainValidationForTrusted**: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors. Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

**GracePeriod**: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated.

**HeaderCharset**: Charset of the header. If not empty, the one specified in the message header will be ignored.

**IgnoreChainLoops**: Whether chain loops should be ignored.Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves.

**IgnoreOCSPNoCheckExtension**: Whether the OCSP NoCheck extension should be ignored.Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues.

**IgnoreSystemTrust**: Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component should trust the certificates residing in the Trusted Root Certification Authorities store.

If [IgnoreSystemTrust](#IgnoreSystemTrust) is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the TrustedCertificates property) are considered trusted.

**ImplicitlyTrustSelfSignedCertificates**: Whether to trust self-signed certificates. Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows emulating the verifying environment without actually changing its security settings.

**MaxHeaderSize**: Specifies the maximum mail message header size in bytes.Use this property to adjust the maximum size of a mail message header. If no header end (CRLFCRLF) found, the header is considered blank. Default size is 32768 (i.e. 32KB).

**PromoteLongOCSPResponses**: Whether long OCSP responses are requested. Set this property to True to force the component to publish the 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

**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.

**TextCharset**: Charset of text parts, if any. If not empty, the one specified in the message text parts will be ignored.

**TolerateMinorChainIssues**: Whether to tolerate minor chain issues.This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

- CA, revocation source, TLS key usage requirements are not mandated
- Violation of OCSP issuer requirements are ignored
- The AuthorityKeyID extension in CRL- and certificate-issuing CAs are ignored (helps with incorrectly renewed certificates)
- Basic constraints and name constraints of CA certificates are ignored
- Some weaker algorithms are tolerated

**UseEnvStorages**: Enables or disables use of the environment storages.Enable this property to make the chain validation module automatically look up missing CA and intermediate certificates in the environment storages.

**UseMicrosoftCTL**: Enables or disables the automatic use of the Microsoft online certificate trust list.Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

**UseSystemCertificates**: Enables or disables the use of the system certificates.Use this property to tell the chain validation module to automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

**UseValidationCache**: Enables or disable the use of the product-wide certificate chain validation cache.Use this property to enable or disable the use of the global chain validation cache. If enabled, the component will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the component, both interim and final, will be saved in the cache and available for re-use by any future validations. Disable this property to ignore the cache and always perform the validation from a fresh start.

### 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 component.

Supported values are:

|  |  |  |
| --- | --- | --- |
| off |  | No caching (default) |
| local |  | Local caching |
| global |  | Global caching |

**Cookies**: Gets or sets local cookies for the component.Use this property to get cookies from the internal cookie storage of the component 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 components 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. If unavailable, exception will be thrown. |
| disable | Do not use hardware cryptography. |

This value will be used by all the HTTP clients including the ones used internally in other components.

**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.

| trace |  | More 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:

|  |  |  |
| --- | --- | --- |
| 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 component. 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 component) 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 component is set to "*local*", the property returns/restores the rules from/to the internal storage of the component. If *StaticDNS* of the component 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 components.

**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. By default, this property is set to ", " value.
