An OpenSSL::OCSP::BasicResponse contains the status of a certificate check which is created from an OpenSSL::OCSP::Request. A BasicResponse is more detailed than a Response.

Adds a certificate status for certificate_id. status is the status, and must be one of these:
-
OpenSSL::OCSP::V_CERTSTATUS_GOOD
-
OpenSSL::OCSP::V_CERTSTATUS_REVOKED
-
OpenSSL::OCSP::V_CERTSTATUS_UNKNOWN
reason and revocation_time can be given only when status is OpenSSL::OCSP::V_CERTSTATUS_REVOKED. reason describes the reason for the revocation, and must be one of OpenSSL::OCSP::REVOKED_STATUS_* constants. revocation_time is the time when the certificate is revoked.
this_update and next_update indicate the time at which ths status is verified to be correct and the time at or before which newer information will be available, respectively. next_update is optional.
extensions is an Array of OpenSSL::X509::Extension to be included in the SingleResponse. This is also optional.
Note that the times, revocation_time, this_update and next_update can be specified in either of Integer or Time object. If they are Integer, it is treated as the relative seconds from the current time.

Signs this OCSP response using the cert, key and optional digest. This behaves in the similar way as OpenSSL::OCSP::Request#sign.
flags can include:

don’t include certificates
- OpenSSL::OCSP::NOTIME

don’t set producedAt
- OpenSSL::OCSP::RESPID_KEY
-
use signer’s public key hash as responderID

Returns an Array of statuses for this response. Each status contains a CertificateId, the status (0 for good, 1 for revoked, 2 for unknown), the reason for the status, the revocation time, the time of this update, the time for the next update and a list of OpenSSL::X509::Extension.
This should be superseded by BasicResponse#responses and find_response that return SingleResponse.
