The MessageVerifier component verifies digital signatures of data stored in the PKCS#7 format.
Syntax
TsbxMessageVerifier
Remarks
PKCS#7 (Public Key Cryptography Standard #7) is a common format used to store encrypted and signed data.
It is used by a variety of protocols, including S/MIME and CMS.
MessageVerifier verifier = new MessageVerifier();
// Select the file which contains the signed message
verifier.setInputFile("signedMessage.bin");
if (verifier.checkSignatureType() == Constants.stPKCS7Detached)
{
// To verify a detached signature, we need
// to provide both the signature and the original data
verifier.setDataFile("message.txt");
verifier.verifyDetached();
}
else
{
// To verify an enveloping signature, we need
// to provide the location to extract the data
verifier.setOutputFile("output.txt");
verifier.verify();
}
System.out.println("Validation result: " + verifier.getSignatureValidationResult() + "\n" +
"Signing time: " + verifier.getValidatedSigningTime() + "\n" +
"TSA certificate: " + verifier.getSigningCertificate().getSubjectRDN());
// Output:
//
// Validation result: 0 // 0 == svtValid
// Signing time: 2024-05-16 15:18:35

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, you must call Config("PROPERTY"). The value will be returned as a string.
DoAction Method (MessageVerifier Component)
Performs an additional action.
Syntax
function DoAction(ActionID: String; ActionParams: String): String;
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;....
Reset Method (MessageVerifier Component)
Resets the component settings.
Syntax
procedure Reset();
Remarks
Reset is a generic method available in every component.
Verify Method (MessageVerifier Component)
Verifies digitally signed data.
Syntax
procedure Verify();
Remarks
PKCS#7 and its successor, CMS, support two types of signatures: (1) enveloping signatures, where the signed data and its signature are combined in the same message, and (2) detached signatures, where the signature is stored as a separate entity. This method verifies enveloped signatures and extracts data contained in them. Use VerifyDetached to verify detached signatures.
This method expects the enveloping signature to be provided via InputFile or InputStream properties.
Note that this method only checks the integrity of the signature, i.e., that it is signed with the claimed certificate and has not been altered. It does not validate the signing certificate chain. To validate the certificate chain, either use CertificateValidator component together with MessageVerifier, or consider using CAdESVerifier component instead.
VerifyDetached Method (MessageVerifier Component)
Verifies a detached signature.
Syntax
procedure VerifyDetached();
Remarks
Use this method to verify detached signatures. Pass the signature via InputFile (or InputStream) property, and the original data via DataFile (DataStream).

Syntax
type TNotificationEvent = procedure ( Sender: TObject; const EventID: String; const EventParam: String ) of Object;
property OnNotification: TNotificationEvent 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.
RecipientFound Event (MessageVerifier Component)
Fires to report a message addressee parameters.
Syntax
type TRecipientFoundEvent = procedure ( Sender: TObject; const IssuerRDN: String; const SerialNumber: TBytes; const SubjectKeyID: TBytes; CertFound: Boolean ) of Object;
property OnRecipientFound: TRecipientFoundEvent read FOnRecipientFound write FOnRecipientFound;
Remarks
This event is fired for each addressee the message is encrypted for. It may fire several times in a row if the message is encrypted for more than one recipient.
The IssuerRDN, SerialNumber, and SubjectKeyID parameters to identify the recipient's certificate. CertFound indicates if the specified certificate has been located in Certificates collection. If it wasn't, you might want to look up the certificate manually, and add it to the collection inside the event handler.
SignatureFound Event (MessageVerifier Component)
Signifies the start of signature validation.
Syntax
type TSignatureFoundEvent = procedure ( Sender: TObject; const IssuerRDN: String; const SerialNumber: TBytes; const SubjectKeyID: TBytes; CertFound: Boolean; var ValidateSignature: Boolean; var ValidateChain: Boolean ) of Object;
property OnSignatureFound: TSignatureFoundEvent 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 SignatureValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
SignatureValidated Event (MessageVerifier Component)
Marks the completion of the signature validation routine.
Syntax
type TSignatureValidatedEvent = procedure ( Sender: TObject; const IssuerRDN: String; const SerialNumber: TBytes; const SubjectKeyID: TBytes; ValidationResult: Integer ) of Object;
property OnSignatureValidated: TSignatureValidatedEvent 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. |

property OnTimestampFound: TTimestampFoundEvent read FOnTimestampFound write FOnTimestampFound;
Remarks
This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters.
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.
Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the ValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
TimestampValidated Event (MessageVerifier Component)
Reports the completion of the timestamp validation routine.
Syntax
type TTimestampValidatedEvent = procedure ( Sender: TObject; const IssuerRDN: String; const SerialNumber: TBytes; const SubjectKeyID: TBytes; const Time: String; ValidationResult: Integer; ChainValidationResult: Integer; ChainValidationDetails: Integer ) of Object;
property OnTimestampValidated: TTimestampValidatedEvent read FOnTimestampValidated write FOnTimestampValidated;
Remarks
This event is fired upon the completion of the timestamp validation routine, and reports the respective validation result.
ValidationResult is set to 0 if the validation has been successful, or to a non-zero value in case of a 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. |

Certificate Type
Encapsulates an individual X.509 certificate.
Remarks
This type keeps and provides access to X.509 certificate details.
Fields
Bytes
TBytes (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 property when generating a new certificate to have its Basic Constraints extension generated automatically.
CAKeyID
TBytes (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
TsbxCertTypes (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 component 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 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.
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.
Handle
Int64
Default Value: 0
Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.
When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object
after such operation.
pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
HashAlgorithm
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.

IssuerRDN
String
Default Value: ""
A list of Property=Value pairs that uniquely identify the certificate issuer.
Example: /C=US/O=Nationwide CA/CN=Web Certification Authority

Use the KeyBits, Curve, and PublicKeyBytes properties to get more details about the key the certificate contains.
KeyBits
Integer (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 property 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 property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.
KeyUsage
Integer
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 property 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 property 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
Integer (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 property 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
TBytes (read-only)
Default Value: ""
Returns the certificate's private key in DER-encoded format. It is normal for this property 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 property 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
TBytes (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
TsbxQualifiedStatementsTypes
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
TBytes
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
TsbxPKISources (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
TBytes
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 properties 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.
Constructors
>
constructor Create();
Creates a new object with default field values.
SignatureAttribute Type
Represents an attribute of a digital PKCS#7/CMS signature.
Remarks
Attributes store auxiliary information about the signed message, the signature, or the owner. Each attribute is a OID=Value pair.
Common attributes are signing time, a content type, a policy identifier, and a signature timestamp.

constructor Create();
Creates a new TimestampInfo object with default field values.
Config Settings (MessageVerifier 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 method.MessageVerifier Config Settings
