Hi,
Wow! Thanks! I will give this a try a little later and post back.
Thanks,

I think I have got the example working. I attached a jmx file and a cert
to this mail and maybe we are lucky and the mailing list doesn't strip
it from the mail.
In case it does:
Add the variable "certpath" to your testplan (either by a cvs datasource
for more than one cert, or via the test plan root element). It should
point to your x509 certificates path.
Add a HTTP Sampler with method POST, the "Body Data" tab selected and
filled with "${ocspReq}".
Add a JSR223 PreProcessor to the sampler (set to groovy -- the default)
with the following content:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.Reader;
import org.bouncycastle.cert.ocsp.CertificateID;
import org.bouncycastle.cert.ocsp.OCSPReq;
import org.bouncycastle.cert.ocsp.OCSPReqBuilder;
import org.bouncycastle.cert.X509CertificateHolder;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.operator.DigestCalculatorProvider;
import org.bouncycastle.operator.jcajce.JcaDigestCalculatorProviderBuilder;
String fName = vars.get("certpath");
Reader fR = new BufferedReader(new FileReader(fName));
PEMParser pPar = new PEMParser(fR);
X509CertificateHolder obj = (X509CertificateHolder)pPar.readObject();
DigestCalculatorProvider dCP = new
JcaDigestCalculatorProviderBuilder().build();
CertificateID cId = new CertificateID(dCP.get(CertificateID.HASH_SHA1),
obj, obj.getSerialNumber());
OCSPReq oReq = new OCSPReqBuilder().addRequest(cId).build();
byte[] asn1seq = oReq.getEncoded();
String sb = new String(asn1seq, "ISO-8859-1");
vars.put("ocspReq", sb);
Add a JSR223 Assertion to the sampler (set to groovy, again) containing:
import org.bouncycastle.cert.ocsp.OCSPResp;
def sR = ctx.getPreviousResult();
byte[] instream = sR.getResponseData();
OCSPResp oResp = new OCSPResp(instream);
assert oResp.getStatus() ==0
Add a Header Manager to the sampler with the following set:
Content-Type application/ocsp-request
Accept application/ocsp-response
It seemed to work for me (famous last words)
One important change was to use "ISO-8859-1" for the encoding of the string.
