Interface: TimeStampProviderBase

Defines a contract for providing trusted timestamp tokens for arbitrary binary data.

Methods

buildTimeStampToken()

buildTimeStampToken(dataHash, timeStampParams): Promise<Uint8Array<ArrayBufferLike>>;

Generates a timestamp token (RFC 3161) for the provided data hash.

Parameters

dataHash

Uint8Array

The data hash to be timestamped.

timeStampParams

TimeStampParams

The TimeStampParams returned by TimeStampProviderBase.getTimeStampParams.

Returns

Promise<Uint8Array<ArrayBufferLike>>

A promise that resolves to a DER-encoded timestamp token.

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.
