    • TimeStampRequest

      public TimeStampRequest(byte[] req) throws IOException
      Create a TimeStampRequest from the past in byte array.
      Parameters:
      req - byte array containing the request.
      Throws:
      IOException - if the request is malformed.

    • TimeStampRequest

      public TimeStampRequest(InputStream in) throws IOException
      Create a TimeStampRequest from the past in input stream.
      Parameters:
      in - input stream containing the request.
      Throws:
      IOException - if the request is malformed.

  • Method Details

    • toASN1Structure

      public org.bouncycastle.asn1.tsp.TimeStampReq toASN1Structure()
      Returns:
      the underlying ASN.1 TimeStampReq structure.

    • getVersion

      public int getVersion()
      Returns:
      the version of the request (1 for RFC 3161).

    • getMessageImprint

      public org.bouncycastle.asn1.tsp.MessageImprint getMessageImprint()
      Returns:
      the message imprint (hash algorithm plus digest) to be stamped.

    • getMessageImprintAlgOID

      public org.bouncycastle.asn1.ASN1ObjectIdentifier getMessageImprintAlgOID()
      Returns:
      the OID of the hash algorithm used for the message imprint.

    • getMessageImprintAlgID

      public org.bouncycastle.asn1.x509.AlgorithmIdentifier getMessageImprintAlgID()
      Returns:
      the algorithm identifier of the hash used for the message imprint.

    • getMessageImprintDigest

      public byte[] getMessageImprintDigest()
      Returns:
      the digest value to be stamped.

    • getReqPolicy

      public org.bouncycastle.asn1.ASN1ObjectIdentifier getReqPolicy()
      Returns:
      the OID of the TSA policy the requester asks the token to be issued under, null if not set.

    • getNonce

      public BigInteger getNonce()
      Returns:
      the nonce included in the request, null if there is none.

    • getCertReq

      public boolean getCertReq()
      Returns:
      true if the requester asked the TSA to include its certificate(s) in the response, false if absent (the RFC 3161 default).

    • validate

      public void validate(Set algorithms, Set policies, Set extensions) throws TSPException
      Validate the timestamp request, checking the digest to see if it is of an accepted type and whether it is of the correct length for the algorithm specified.
      Parameters:
      algorithms - a set of OIDs giving accepted algorithms.
      policies - if non-null a set of policies OIDs we are willing to sign under.
      extensions - if non-null a set of extensions OIDs we are willing to accept.
      Throws:
      TSPException - if the request is invalid, or processing fails.

    • getEncoded

      public byte[] getEncoded() throws IOException
      return the ASN.1 encoded representation of this object.
      Returns:
      the default ASN.1 byte encoding for the object.
      Throws:
      IOException

    • hasExtensions

      public boolean hasExtensions()
      Returns:
      true if the request carries any extensions, false otherwise.

    • getExtension

      public org.bouncycastle.asn1.x509.Extension getExtension(org.bouncycastle.asn1.ASN1ObjectIdentifier oid)
      Return the extension with the passed in OID.
      Parameters:
      oid - the OID of the extension of interest.
      Returns:
      the extension, null if not present.

    • getExtensionOIDs

      public List getExtensionOIDs()
      Returns:
      a list of the OIDs of the extensions present, in order, empty if there are none.

    • getNonCriticalExtensionOIDs

      public Set getNonCriticalExtensionOIDs()
      Returns a set of ASN1ObjectIdentifiers giving the non-critical extensions.
      Returns:
      a set of ASN1ObjectIdentifiers.

    • getCriticalExtensionOIDs

      public Set getCriticalExtensionOIDs()
      Returns a set of ASN1ObjectIdentifiers giving the critical extensions.
      Returns:
      a set of ASN1ObjectIdentifiers.
