What versions of XAdES are supported?

XAdES versions 1.1.1, 1.2.2, 1.3.2 and 1.4.1 (1.4.2) are supported.
For XAdES (XAdES-BES, XAdES-EPES) and XAdES-T forms, there is a simple interface available via TElXAdESSigner and TElXMLVerifier classes.
The TElXAdESSigner and TElXMLVerifier classes have a QualifyingProperties property that fully implements QualifyingProperties element from XAdES specification. All other XAdES forms are controlled through this QualifyingProperties property.

Creating a countersignature and all timestamping could be done using ElXAdESProcessor methods. For example:

ElXAdESSigner.AddSigAndRefsTimestamp (XAdES-X), ElXAdESVerifier.AddArchiveTimestamp (XAdES-A)

But, some properties such as Id, don't have corresponding method/property in TElXAdESSigner and can be set only via QualifyingProperties property.

Next, if you need to set AttributeCertificateRefs (XAdES-C form), you will need to set it directly using ElXAdESSigner.QualifyingProperties.UnsignedProperties.UnsignedSignatureProperties.AttributeCertificateRefs property.

Example of how to fill RevocationValues and CompleteRevocationRefs with OCSP response (C# notation):

---

ElXAdESSigner.XAdESForm = SBXMLAdES.Unit. XAdES_X_L;
ElXAdESSigner.Generate(); // generate QualifyingProperties structure

...

TElOCSPResponse OCSPResponse; // for example we have OCSP response already
int Size = 0;
byte[] OCSPResponseBuf;
OCSPResponse.Save(ref OCSPResponseBuf, 0, ref Size);
OCSPResponseBuf = new Byte
if (OCSPResponse.Save(ref OCSPResponseBuf, 0, ref Size))

{

 SBUtils.Unit.SetLength(OCSPResponseBuf, Size);
 TElXMLEncapsulatedPKIData PKIData = new TElXMLEncapsulatedPKIData(XAdESSigner.XAdESVersion);
 PKIData.Encoding = SBXMLAdES.Unit.xemDER;
 PKIData.Data = BufPKI;
 ElXAdESSigner.QualifyingProperties.UnsignedProperties.UnsignedSignatureProperties.RevocationValues.OCSPValues.Add(PKIData);

TElXMLOCSPRef OCSPRef = new TElXMLOCSPRef(XAdESSigner.XAdESVersion);
if (FResponderID.Name.Count > 0)
{
OCSPRef.OCSPIdentifier.ResponderID = SBXMLSec.Unit.FormatRDN(OCSPResponse.ResponderID.Name);
OCSPIdentifier.ResponderIDType = SBXMLAdES.Unit.xrtByName;
}

else
if (FResponderID.FSHA1KeyHash.Length() > 0)
{
OCSPRef.DigestAlgAndValue.DigestMethod = xmlDigestMethodSHA1;
OCSPRef.DigestAlgAndValue.DigestValue = OCSPResponse.ResponderID.SHA1KeyHash;
OCSPIdentifier.ResponderIDType = SBXMLAdES.Unit.xrtByKey
}
OCSPRef.OCSPIdentifier.ProducedAtUTC = OCSPResponse.ProducedAt;
ElXAdESSigner.QualifyingProperties.UnsignedProperties.UnsignedSignatureProperties.CompleteRevocationRefs.OCSPRefs.Add(OCSPRef);
}
