Instance Method Details

#cert_status ⇒ Integer

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When the status is V_CERTSTATUS_REVOKED, the time at which the certificate was revoked can be retrieved by #revocation_time.

Returns:

#check_validity(nsec = 0, maxsec = -1) ⇒ Object

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.
