TimeStampProvider
Class: TimeStampProvider
Generates a timestamp token by sending a time-stamp request to a Time Stamping Authority (TSA) server.
Implements
Constructors
Constructor
new TimeStampProvider(serverUrl, externalResourcesOptions?): TimeStampProvider;
Creates a new TimeStampProvider.
Parameters
serverUrl
string
The uniform resource identifier for the Time Stamping Authority (TSA) server providing the time-stamp.
externalResourcesOptions?
Returns
TimeStampProvider
Accessors
externalResourcesOptions
Get Signature
get externalResourcesOptions(): ExternalResourcesOptions;
Gets configuration options used to retrieve external TSA response.
Returns
The current external resources configuration, or undefined
if default behavior is used.
Set Signature
set externalResourcesOptions(value): void;
Sets configuration options used to retrieve external TSA response.
Parameters
value
The external resources configuration to apply,
or undefined to use the default behavior.
Returns
void
hashAlgorithmOID
Get Signature
get hashAlgorithmOID(): string;
Gets the object identifier (OID) of hash algorithm used to encode the time-stamp request, default is SHA-256. Note! The list of supported algorithms defined by the TSA server used.
Returns
string
Set Signature
set hashAlgorithmOID(value): void;
Sets the object identifier (OID) of hash algorithm used to encode the time-stamp request, default is SHA-256. Note! The list of supported algorithms defined by the TSA server used.
Parameters
value
string
Returns
void
serverUrl
Get Signature
get serverUrl(): string;
Gets the uniform resource identifier for the Time Stamping Authority (TSA) server providing the time-stamp.
Returns
string
Set Signature
set serverUrl(value): void;
Sets the uniform resource identifier for the Time Stamping Authority (TSA) server providing the time-stamp.
Parameters
value
string
Returns
void
Methods
buildTimeStampToken()
buildTimeStampToken(dataHash, _): Promise<Uint8Array<ArrayBufferLike>>;
Generates a timestamp token (RFC 3161) for the provided data hash.
Parameters
dataHash
Uint8Array
The data hash to be timestamped.
_
Returns
Promise<Uint8Array<ArrayBufferLike>>
A promise that resolves to a DER-encoded timestamp token.
Implementation of
TimeStampProviderBase.buildTimeStampToken
getTimeStampParams()
getTimeStampParams(): Promise<TimeStampParams>;
Prepares parameters required for the first stage of the timestamping process.
This method performs validation, initializes timestamping-related data, and collects all inputs required for building the final timestamp container. It corresponds to the "preparation stage" of timestamping.
Returns
Promise<TimeStampParams>
A TimeStampParams object containing parameters required for timestamp generation
Throws
If the configured timestamp format is invalid or unsupported.
