GetEncoded()

		IX509Certificate	issuerCert,
		String	url
	)

Fetch a DER-encoded BasicOCSPResponse from an OCSP responder.

Fetch a DER-encoded BasicOCSPResponse from an OCSP responder. The method should not throw an exception.

Note: do not pass in the full DER-encoded OCSPResponse object obtained from the responder, only the DER-encoded BasicOCSPResponse value contained in the response data.

Parameters

checkCert	Certificate to check.
issuerCert	The parent certificate.
url	The URL of the OCSP responder endpoint. If null, implementations can attempt to obtain a URL from the AuthorityInformationAccess extension of the certificate, or from another implementation-specific source.

Returns

a byte array containing a DER-encoded BasicOCSPResponse structure or null if one could not be obtained
