Class DefaultTimeStampTokenProvider

java.lang.Object
  xades4j.providers.impl.DefaultTimeStampTokenProvider

All Implemented Interfaces:

TimeStampTokenProvider

public class DefaultTimeStampTokenProvider
extends Object
implements TimeStampTokenProvider

Default implementation of TimeStampTokenProvider. It uses the SUN proprietary API in the sun.security.timestamp and sun.security.pkcs packages. By default it used simple HTTP to get the time-stamp token from the TSA at http://tss.accv.es:8318/tsa. Both the Timestamper and the TSA URL can be overriden.

The TSA certificate is requested. If the token is granted with mods, a check is made to ensure that the mod wasn't not providing the certificate. If so, an exception is thrown.

Description copied from interface: TimeStampTokenProvider

Gets a time-stamp token.

Specified by:

getTimeStampToken in interface TimeStampTokenProvider

Parameters:

tsDigestInput - the input for the digest to be sent to the TSA

digestAlgUri - the digest algorithm that should be used to calculate the digest

Returns:

the time-stamp token data

Throws:

TimeStampTokenGenerationException - if there's an error getting the time-stamp

getTimestamper

protected sun.security.timestamp.Timestamper getTimestamper()

Gets the Timestamper to be used. Override to change this behaviour. By default, this method invokes getTSAUrl to create an HttpTimestamper.

Returns:

the timestamper

getTSAUrl

protected String getTSAUrl()

Gets the TSA URL when the default HttpTimestamper is used. Override to change the TSA in use.

Returns:

the url (default is http://tss.accv.es:8318/tsa
