MailReader Class
Properties Methods Events Config Settings Errors
The MailReader class implements parsing and decryption of e-mail messages.
Syntax
secureblackbox.MailReader
Remarks
MailReader parses and decrypts e-mail messages, as well as verifies electronic signatures.
Loading a e-mail message and accessing its properties:
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:
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:
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");

Remarks
Use this property to access the attachments of the loaded message.
This property is read-only.
Please refer to the MailAttachment type for a complete list of fields.Bcc Property (MailReader Class)
The contents of the BCC header field of the Message.
Syntax
public MailAddressList getBcc();
Remarks
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.
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.BlockedCertificates Property (MailReader Class)
The certificates that must be rejected as trust anchors.
Syntax
public CertificateList getBlockedCertificates(); public void setBlockedCertificates(CertificateList blockedCertificates);
Remarks
Use this property to provide a list of compromised or blocked certificates. Any chain containing a blocked certificate will fail validation.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.Cc Property (MailReader Class)
The value of the CC header field of the Message.
Syntax
public MailAddressList getCc();
Remarks
The CC field contains the addresses of secondary recipients of the message.
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.DecryptionCertificate Property (MailReader Class)
The certificate to be used for decryption.
Syntax
public Certificate getDecryptionCertificate(); public void setDecryptionCertificate(Certificate decryptionCertificate);
Remarks
Use this property to provide the decryption certificate. The decryption certificate must have a private key associated with it.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.ExternalCrypto Property (MailReader Class)
Provides access to external signing and DC parameters.
Syntax
public ExternalCrypto getExternalCrypto();
Remarks
Use this property to tune-up remote cryptography settings. SecureBlackbox supports two independent types of external cryptography: synchronous (based on the ExternalSign event) and asynchronous (based on the DC protocol and the DCAuth signing component).
This property is read-only.
Please refer to the ExternalCrypto type for a complete list of fields.FIPSMode Property (MailReader Class)
Reserved.
Syntax
public boolean isFIPSMode(); public void setFIPSMode(boolean FIPSMode);
Default Value
False
Remarks
This property is reserved for future use.
From Property (MailReader Class)
Contains the value of the From header of the Message.
Syntax
public MailAddressList getFrom();
Remarks
This field contains address(es) of message author(s). If the actual sender is not the author of the message, the sender is provided separately via Sender property.
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.IgnoreChainValidationErrors Property (MailReader Class)
Makes the class tolerant to chain validation errors.
Syntax
public boolean isIgnoreChainValidationErrors(); public void setIgnoreChainValidationErrors(boolean ignoreChainValidationErrors);
Default Value
False
Remarks
If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.
KnownCertificates Property (MailReader Class)
Additional certificates for chain validation.
Syntax
public CertificateList getKnownCertificates(); public void setKnownCertificates(CertificateList knownCertificates);
Remarks
Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually.
The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.
Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.KnownCRLs Property (MailReader Class)
Additional CRLs for chain validation.
Syntax
public CRLList getKnownCRLs(); public void setKnownCRLs(CRLList knownCRLs);
Remarks
Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.
This property is not available at design time.
Please refer to the CRL type for a complete list of fields.KnownOCSPs Property (MailReader Class)
Additional OCSP responses for chain validation.
Syntax
public OCSPResponseList getKnownOCSPs(); public void setKnownOCSPs(OCSPResponseList knownOCSPs);
Remarks
Use this property to supply additional OCSP responses that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated OCSP responses are stored separately from the signed message or document.
This property is not available at design time.
Please refer to the OCSPResponse type for a complete list of fields.Message Property (MailReader Class)
The message that is currently stored in the class.
Syntax
public MailMessage getMessage(); public void setMessage(MailMessage message);
Remarks
Use this property to access the message that has been processed and populated by class.
This property is not available at design time.
Please refer to the MailMessage type for a complete list of fields.OfflineMode Property (MailReader Class)
Switches the class to offline mode.
Syntax
public boolean isOfflineMode(); public void setOfflineMode(boolean offlineMode);
Default Value
False
Remarks
When working in offline mode, the class restricts itself from using any online revocation information sources, such as CRL or OCSP responders.
Offline mode may be useful if there is a need to verify the completeness of the validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.
OtherHeaders Property (MailReader Class)
Contains secondary headers of the mail message.
Syntax
public StringNameValuePairList getOtherHeaders();
Remarks
Use this property to access the headers that have not been published in first-level object's properties.
This property is read-only.
Please refer to the StringNameValuePair type for a complete list of fields.Profile Property (MailReader Class)
Specifies a pre-defined profile to apply when creating the signature.
Syntax
public String getProfile(); public void setProfile(String profile);
Default Value
""
Remarks
Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.
Proxy Property (MailReader Class)
The proxy server settings.
Syntax
public ProxySettings getProxy();
Remarks
Use this property to tune up the proxy server settings.
This property is read-only.
Please refer to the ProxySettings type for a complete list of fields.ReplyTo Property (MailReader Class)
The value of the Reply-To header field of the Message.
Syntax
public MailAddressList getReplyTo();
Remarks
This field contains the addresses to which the replies to this message should be sent. This field is optional. If not specified, the replies should be sent to the addresses specified in the From field.
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.RevocationCheck Property (MailReader Class)
Specifies the kind(s) of revocation check to perform for all chain certificates.
Syntax
public int getRevocationCheck(); public void setRevocationCheck(int revocationCheck); Enumerated values: public final static int crcNone = 0; public final static int crcAuto = 1; public final static int crcAllCRL = 2; public final static int crcAllOCSP = 3; public final static int crcAllCRLAndOCSP = 4; public final static int crcAnyCRL = 5; public final static int crcAnyOCSP = 6; public final static int crcAnyCRLOrOCSP = 7; public final static int crcAnyOCSPOrCRL = 8;
Default Value
1
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.
SecurityInfo Property (MailReader Class)
Contains the Message's security info.
Syntax
public MailSecurityInfo getSecurityInfo();
Remarks
Use this property to check the security information about the Message, such as whether the message is signed or the encryption algorithm used.
This property is read-only.
Please refer to the MailSecurityInfo type for a complete list of fields.Sender Property (MailReader Class)
The value of the Sender header field of the Message.
Syntax
public MailAddress getSender();
Remarks
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 the same entity, the "Sender:" field is not used ("From:" used instead).
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.SendTo Property (MailReader Class)
The value of the To header field of the Message.
Syntax
public MailAddressList getSendTo();
Remarks
This field specifies the address(es) of the primary recipient(s) of the message.
This property is read-only.
Please refer to the MailAddress type for a complete list of fields.SigningCertificate Property (MailReader Class)
The certificate of the signature creator.
Syntax
public Certificate getSigningCertificate();
Remarks
Use this property to access the certificate that was used to create the signature.
This property is read-only and not available at design time.

This property is read-only.
Please refer to the SocketSettings type for a complete list of fields.TLSSettings Property (MailReader Class)
Manages TLS layer settings.
Syntax
public TLSSettings getTLSSettings();
Remarks
Use this property to tune up the TLS layer parameters.
This property is read-only.
Please refer to the TLSSettings type for a complete list of fields.TrustedCertificates Property (MailReader Class)
A list of trusted certificates for chain validation.
Syntax
public CertificateList getTrustedCertificates(); public void setTrustedCertificates(CertificateList trustedCertificates);
Remarks
Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.
Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.UsedCertificates Property (MailReader Class)
Contains a list of certificates used during the chain validation routine.
Syntax
public CertificateList getUsedCertificates();
Remarks
Use this property to access the list of certificates that were used during the chain validation.
This property is read-only and not available at design time.
Please refer to the Certificate type for a complete list of fields.ValidationMoment Property (MailReader Class)
The time point at which signature validity is to be established.
Syntax
public String getValidationMoment(); public void setValidationMoment(String validationMoment);
Default Value
""
Remarks
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.
Config Method (MailReader Class)
Sets or retrieves a configuration setting.
Syntax
public String config(String configurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
DoAction Method (MailReader Class)
Performs an additional action.
Syntax
public String doAction(String actionID, String actionParams);
Remarks
DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.
The unique identifier (case insensitive) of the action is provided in the ActionID parameter.
ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....
Common ActionIDs:
Action | Parameters | Returned value | Description |
ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |

Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void decryptionInfoNeeded(MailReaderDecryptionInfoNeededEvent e) {} ... } public class MailReaderDecryptionInfoNeededEvent { public String issuerRDN; public byte[] serialNumber; public byte[] subjectKeyID; }
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 Class)
Reports information about errors during e-mail message loading, parsing or saving.
Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void error(MailReaderErrorEvent e) {} ... } public class MailReaderErrorEvent { public int errorCode; public String description; }
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 Class)
Handles remote or external decryption.
Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void externalDecrypt(MailReaderExternalDecryptEvent e) {} ... } public class MailReaderExternalDecryptEvent { public String operationId; public String algorithm; public String pars; public String encryptedData; public String data; //read-write }
Remarks
Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.
The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.
Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16
Notification Event (MailReader Class)
This event notifies the application about an underlying control flow event.
Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void notification(MailReaderNotificationEvent e) {} ... } public class MailReaderNotificationEvent { public String eventID; public String eventParam; }
Remarks
The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.
The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.
SignatureFound Event (MailReader Class)
Signifies the start of signature validation.
Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void signatureFound(MailReaderSignatureFoundEvent e) {} ... } public class MailReaderSignatureFoundEvent { public String issuerRDN; public byte[] serialNumber; public byte[] subjectKeyID; public boolean certFound; public boolean validateSignature; //read-write public boolean validateChain; //read-write }
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 class 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 SignatureValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
SignatureValidated Event (MailReader Class)
Marks the completion of the signature validation routine.
Syntax
public class DefaultMailReaderEventListener implements MailReaderEventListener { ... public void signatureValidated(MailReaderSignatureValidatedEvent e) {} ... } public class MailReaderSignatureValidatedEvent { public String issuerRDN; public byte[] serialNumber; public byte[] subjectKeyID; public int validationResult; }
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) |
Certificate Type
Encapsulates an individual X.509 certificate.
Remarks
This type keeps and provides access to X.509 certificate details.
Fields
Bytes
byte[] (read-only)
Default Value: ""
Returns the raw certificate data in DER format.
CA
boolean
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
byte[] (read-only)
Default Value: ""
A unique identifier (fingerprint) of the CA certificate's cryptographic key.
Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.
This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.
CertType
int (read-only)
Default Value: 0
Returns the type of the entity contained in the Certificate object.
A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.
Use the CertificateManager class to load or create new certificate and certificate requests objects.
CRLDistributionPoints
String
Default Value: ""
Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.
Use this 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
String
Default Value: ""
Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Fingerprint
String (read-only)
Default Value: ""
Contains the fingerprint (a hash imprint) of this certificate.
While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.
FriendlyName
String (read-only)
Default Value: ""
Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.
HashAlgorithm
String
Default Value: ""
Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.
KeyBits
int (read-only)
Default Value: 0
Returns the length of the public key in bits.
This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.
KeyFingerprint
String (read-only)
Default Value: ""
Returns a SHA1 fingerprint of the public key contained in the certificate.
Note that the key fingerprint is different from the certificate fingerprint accessible via the Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.
KeyUsage
int
Default Value: 0
Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.
This value is a bit mask of the following values:
ckuUnknown | 0x00000 | Unknown key usage |
ckuDigitalSignature | 0x00001 | Digital signature |
ckuNonRepudiation | 0x00002 | Non-repudiation |
ckuKeyEncipherment | 0x00004 | Key encipherment |
ckuDataEncipherment | 0x00008 | Data encipherment |
ckuKeyAgreement | 0x00010 | Key agreement |
ckuKeyCertSign | 0x00020 | Certificate signing |
ckuCRLSign | 0x00040 | Revocation signing |
ckuEncipherOnly | 0x00080 | Encipher only |
ckuDecipherOnly | 0x00100 | Decipher only |
ckuServerAuthentication | 0x00200 | Server authentication |
ckuClientAuthentication | 0x00400 | Client authentication |
ckuCodeSigning | 0x00800 | Code signing |
ckuEmailProtection | 0x01000 | Email protection |
ckuTimeStamping | 0x02000 | Timestamping |
ckuOCSPSigning | 0x04000 | OCSP signing |
ckuSmartCardLogon | 0x08000 | Smartcard logon |
ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication |
ckuKeyPurposeKDC | 0x20000 | Kerberos - KDC |
Set this field before generating the certificate to propagate the key usage flags to the new certificate.
KeyValid
boolean (read-only)
Default Value: False
Returns True if the certificate's key is cryptographically valid, and False otherwise.
OCSPLocations
String
Default Value: ""
Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.
Set this field before calling the certificate manager's Generate method to propagate it to the new certificate.
The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.
OCSPNoCheck
boolean
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
String
Default Value: ""
Contains identifiers (OIDs) of the applicable certificate policies.
The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.
Set this 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
byte[] (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
boolean (read-only)
Default Value: False
Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.
This field is independent from PrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.
PrivateKeyExtractable
boolean (read-only)
Default Value: False
Indicates whether the private key is extractable (exportable).
PublicKeyBytes
byte[] (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
boolean (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
String (read-only)
Default Value: ""
A list of qualifiers.
Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.
SelfSigned
boolean (read-only)
Default Value: False
Indicates whether the certificate is self-signed (root) or signed by an external CA.
SerialNumber
byte[]
Default Value: ""
Returns the certificate's serial number.
The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.
SigAlgorithm
String (read-only)
Default Value: ""
Indicates the algorithm that was used by the CA to sign this certificate.
A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.
Source
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
String (read-only)
Default Value: ""
The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SubjectRDN.
SubjectAlternativeName
String
Default Value: ""
Returns or sets the value of the Subject Alternative Name extension of the certificate.
Subject alternative names are used to provide additional names that are impractical to store in the main 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
byte[]
Default Value: ""
Contains a unique identifier of the certificate's cryptographic key.
Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.
The SubjectKeyID and CAKeyID fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.
SubjectRDN
String
Default Value: ""
A list of Property=Value pairs that uniquely identify the certificate holder (subject).
Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.
Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.
Valid
boolean (read-only)
Default Value: False
Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.
ValidFrom
String
Default Value: ""
The time point at which the certificate becomes valid, in UTC.
ValidTo
String
Default Value: ""
The time point at which the certificate expires, in UTC.

Creates a new object with default field values.
CRL Type
Represents a Certificate Revocation List.
Remarks
CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.
Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.
Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.
Fields

Specifies the parameters of external cryptographic calls.
Remarks
External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.
Fields
AsyncDocumentID
String
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
String
Default Value: ""

Data
String
Default Value: ""
Additional data to be included in the async state and mirrored back by the requestor.
ExternalHashCalculation
boolean
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
String
Default Value: "SHA256"

SB_HASH_ALGORITHM_SHAKE_256_LEN | SHAKE_256_LEN |
KeyID
String
Default Value: ""
The ID of the pre-shared key used for DC request authentication.
Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret to pass the key itself.
The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.
Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.
Example:
signer.ExternalCrypto.KeyID = "MainSigningKey";
signer.ExternalCrypto.KeySecret = "abcdef0123456789";
KeySecret
String
Default Value: ""
The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.
Read more about configuring authentication in the KeyID topic.
Method
int
Default Value: 0
Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.
Available options:
asmdPKCS1 | 0 |
asmdPKCS7 | 1 |
Mode

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.

Config Settings (MailReader Class)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.MailReader Config Settings
If 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.
- 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

This setting only applies to certificates originating from a Windows system store.
The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.
Syntax:
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
Where:
OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.
PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.
Alias1, Alias2, ...: Optional alternative names recognized during parsing.
Usage Examples:
Map OID 2.5.4.5 to SERIALNUMBER:
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
