I have a small problem during the time stamp... using sample applications or my own. The error its the same:

When i use this code or the sample code:

TElHTTPSClient x = new TElHTTPSClient();
tspClient.HashAlgorithm = SBConstants.Unit.SB_ALGORITHM_DGST_SHA1;
tspClient.HTTPClient = x;
tspClient.URL = "http://timestamping.edelweb.fr/service/tsp";

TElCMSSignature signature = message.get_Signatures(index);

signature.SigningTime = DateTime.Now;

signature.CommitmentTypeIndication.Included = true;
signature.CommitmentTypeIndication.ProofOfOrigin = true;
signature.CommitmentTypeIndication.ProofOfCreation = true;
signature.UsePSS = false;
signature.Sign(cert, chain);

The error is:
Lenght can not be less than cero. Parameter name: Lenght.

Can you help me? I´m really disoriented.

Thanks =)

First, please specify which exactly method does expose the problem. It would be great if you provide us the entire call stack (with "Show non-user code" option turned on) as well.

Second -- did you try the CMSManager sample included to the distribution? Does it expose the same problem?

The method "signature.AddTimestamp(ts­pClient);" is throwing the exception.

Here is the call stack:

System.ArgumentOutOfRangeException was unhandled

And yes the CMSManager and TinySigner have the same problem.

Thank you

This is a problem of ElHTTPSClient component probably caused by some specific reply header. We will investigate it and let you know.

Sincerely yours

This is a fresh issue of build 138, caused by the fact that we've added first line of response to the list of headers and it doesn't contain semicolon ":". I believe some other code (and not only ours) can stop working with this, but we need to have this line. So we will fix the underlying GetHeaderByName method.

Sincerely yours

Does the call stack in you case also point to SBHTTPSClient.TElHTTPSClient.GetHeaderByName? Does the problem occure with our demos?
