org.bouncycastle.asn1.microsoft.TimeStampRequest

All Implemented Interfaces:

org.bouncycastle.asn1.ASN1Encodable, org.bouncycastle.util.Encodable

public class TimeStampRequest
extends org.bouncycastle.asn1.ASN1Object

The Microsoft Authenticode time stamp request, as sent to a legacy (pre-RFC 3161) Authenticode time stamping service (the protocol behind signtool /t; the RFC 3161 protocol is signtool /tr).

 TimeStampRequest ::= SEQUENCE {
    countersignatureType OBJECT IDENTIFIER,
    attributes Attributes OPTIONAL,
    content  ContentInfo
 }
 

The countersignatureType identifying a time stamp countersignature is the exact OID 1.3.6.1.4.1.311.3.2.1 (MicrosoftObjectIdentifiers.microsoftTimeStampRequest). No attributes are currently included in requests. The content is a PKCS#7 ContentInfo of type data whose content is the encryptedDigest (signature) from the SignerInfo of the PKCS#7 SignedData to be time stamped.

On the wire the request travels as the body of an HTTP 1.1 POST, base64 encoded, with Content-Type application/octet-stream. The response is a base64 encoded PKCS#7 SignedData whose SignerInfo the requester copies into the original SignedData as a PKCS#9 countersignature (an unsigned attribute of the original SignerInfo), merging the time stamper's certificates into the original SignedData's certificate set.
