Class: OpenSSL::Timestamp::Request

Relationships & Source Files
Inherits: Object
Defined in: ext/openssl/ossl_ts.c

Overview

Allows to create timestamp requests or parse existing ones. A Request is also needed for creating timestamps from scratch with Factory. When created from scratch, some default values are set:

  • version is set to 1

  • cert_requested is set to true

  • algorithm, message_imprint, policy_id, and nonce are set to false

Class Method Summary

  • .new(file) ⇒ Request constructor

    When creating a Request with the File or string parameter, the corresponding File or string must be DER-encoded.

    #policy_id=("string")  ⇒ String  (rw)  



  

    

Allows to set the object identifier that represents the timestamp policy under which the server shall create the timestamp. This may be left nil, implying that the timestamp server will issue the timestamp using some default policy.
