''

Remarks

Use this property to provide a file containing the timestamped data, either enveloping or detached.

OutputBytes Property (MessageTimestampVerifier Component)

Use this property to read the output the component object has produced.

Syntax

property OutputBytes: TBytes read get_OutputBytes;

Remarks

Read the contents of this property after the operation has completed to read the produced output. This property will only be set if the OutputFile and OutputStream properties had not been assigned.

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

OutputFile Property (MessageTimestampVerifier Component)

Path to the file to save the extracted data to.

Syntax

property OutputFile: String read get_OutputFile write set_OutputFile;

Default Value

''

Remarks

Use this property when validating enveloping timestamps to specify the output file where the extracted message should be saved.

SignatureValidationResult Property (MessageTimestampVerifier Component)

The signature validation result.

Syntax

property SignatureValidationResult: TsbxSignatureValidities read get_SignatureValidationResult;

TsbxSignatureValidities = (
  svtValid,
  svtUnknown,
  svtCorrupted,
  svtSignerNotFound,
  svtFailure
);

Default Value

svtValid

Remarks

Use this property to check the result of the most recent signature validation.

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

SigningCertificate Property (MessageTimestampVerifier Component)

The certificate that was used to create the signature.

Syntax

property SigningCertificate: TsbxCertificate read get_SigningCertificate;

Remarks

Use this property to access the certificate that was used to create the signature. This property might not be available if the signer chose not to include the certificate into the signature.

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

Please refer to the Certificate type for a complete list of fields.

TimestampFormat Property (MessageTimestampVerifier Component)

Returns the format of the processed timestamp.

Syntax

property TimestampFormat: TsbxTimestampFormats read get_TimestampFormat;

TsbxTimestampFormats = (
  mtfUnknown,
  mtfRFC5544,
  mtfCMS,
  mtfTSPReply
);

Default Value

mtfUnknown

Remarks

Use this property to check the format of the processed timestamp blob.

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

ValidatedSigningTime Property (MessageTimestampVerifier Component)

Contains the certified signing time.

Syntax

property ValidatedSigningTime: String read get_ValidatedSigningTime;

Default Value

''

Remarks

Use this property to obtain the signing time as certified by an external timestamp. The time is in UTC.

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

Config Method (MessageTimestampVerifier Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings 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, you must call Config("PROPERTY"). The value will be returned as a string.

DoAction Method (MessageTimestampVerifier 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;....

Verify Method (MessageTimestampVerifier Component)

Verifies a timestamped message.

Syntax

procedure Verify();

Remarks

Use this method to verify the enveloping timestamped message provided via InputFile (or InputStream). The original message will be extracted and saved to OutputFile (OutputStream).

Use VerifyDetached to verify detached timestamps.

VerifyDetached Method (MessageTimestampVerifier Component)

Verifies a detached timestamped message.

Syntax

procedure VerifyDetached();

Remarks

Use this method to verify the detached timestamped message provided via InputFile (or InputStream). Please provide the original data via DataFile or DataStream property. You do not need to provide OutputFile and OutputStream, as no data is extracted during this call.

Use Verify to verify enveloping timestamps.

Error Event (MessageTimestampVerifier Component)

Information about errors during PKCS#7 message encryption.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent 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. For a list of valid error codes and their descriptions, please refer to the Messages section.

Notification Event (MessageTimestampVerifier Component)

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

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.

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Constructors

>

constructor Create();

Creates a new object with default field values.

Config Settings (MessageTimestampVerifier 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.
