## Class TimeStampRequest

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.microsoft.TimeStampRequest

- All Implemented Interfaces:
    ASN1Encodable, Encodable

      public class TimeStampRequest
      extends 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.
