class OpenSSL::OCSP::SingleResponse
An OpenSSL::OCSP::SingleResponse
represents an OCSP
SingleResponse
structure, which contains the basic information of the status of the certificate.
Public Class Methods
Creates a new SingleResponse
from der_string.
static VALUE ossl_ocspsres_initialize(VALUE self, VALUE arg) { OCSP_SINGLERESP *res, *res_new; const unsigned char *p; arg = ossl_to_der_if_possible(arg); StringValue(arg); GetOCSPSingleRes(self, res); p = (unsigned char*)RSTRING_PTR(arg); res_new = d2i_OCSP_SINGLERESP(NULL, &p, RSTRING_LEN(arg)); if (!res_new) ossl_raise(eOCSPError, "d2i_OCSP_SINGLERESP"); SetOCSPSingleRes(self, res_new); OCSP_SINGLERESP_free(res); return self; }
Public Instance Methods
Returns the status of the certificate identified by the certid. The return value may be one of these constant:
-
V_CERTSTATUS_GOOD
-
V_CERTSTATUS_REVOKED
-
V_CERTSTATUS_UNKNOWN
When the status is V_CERTSTATUS_REVOKED, the time at which the certificate was revoked can be retrieved by revocation_time
.
static VALUE ossl_ocspsres_get_cert_status(VALUE self) { OCSP_SINGLERESP *sres; int status; GetOCSPSingleRes(self, sres); status = OCSP_single_get0_status(sres, NULL, NULL, NULL, NULL); if (status < 0) ossl_raise(eOCSPError, "OCSP_single_get0_status"); return INT2NUM(status); }
Returns the CertificateId
for which this SingleResponse
is.
static VALUE ossl_ocspsres_get_certid(VALUE self) { OCSP_SINGLERESP *sres; OCSP_CERTID *id; GetOCSPSingleRes(self, sres); id = OCSP_CERTID_dup((OCSP_CERTID *)OCSP_SINGLERESP_get0_id(sres)); /* FIXME */ return ossl_ocspcertid_new(id); }
Checks the validity of thisUpdate and nextUpdate fields of this SingleResponse
. This checks the current time is within the range thisUpdate to nextUpdate.
It is possible that the OCSP
request takes a few seconds or the time is not accurate. To avoid rejecting a valid response, this method allows the times to be within nsec seconds of the current time.
Some responders don’t set the nextUpdate field. This may cause a very old response to be considered valid. The maxsec parameter can be used to limit the age of responses.

Encodes this SingleResponse
