Signature Types

The sample codes for creating different types of signatures stated in the standarts are listed below. See the section Signature Types for the information about signature types

The sample codes are in the package tr.gov.tubitak.uekae.esya.api.xades.example.formats.

BES signature creation is as follows:

// create context with working directory
Context context = createContext();

// create signature according to context,
// with default type (XADES_BES)
XMLSignature signature = new XMLSignature(context);

// add document as reference, but do not embed it
// into the signature (embed=false)
signature.addDocument("./sample.txt", "text/plain", false);

signature.getSignedInfo().setSignatureMethod(SignatureMethod.RSA_SHA256);

// false-true gets non-qualified certificates while true-false gets qualified ones
X509Certificate cert = JSmartCardManager.getInstance().getSignatureCertificate(true, false);

// add certificate to show who signed the document
signature.addKeyInfo(new ECertificate(cert.getEncoded()));

// now sign it by using smart card
signature.sign(JSmartCardManager.getInstance().getSigner(PIN, cert));

signature.write(new FileOutputStream(BASE_DIR + SIGNATURE_FILENAME));

T signature creation is as follows:

// create context with working directory
Context context = createContext();

// create signature according to context,
// with default type (XADES_BES)
XMLSignature signature = new XMLSignature(context);

// add document as reference, but do not embed it
// into the signature (embed=false)
signature.addDocument("./sample.txt", "text/plain", false);

signature.getSignedInfo().setSignatureMethod(SignatureMethod.RSA_SHA256);

// false-true gets non-qualified certificates while true-false gets qualified ones
X509Certificate cert = JSmartCardManager.getInstance().getSignatureCertificate(true, false);

// add certificate to show who signed the document
signature.addKeyInfo(new ECertificate(cert.getEncoded()));

// now sign it by using smart card
signature.sign(JSmartCardManager.getInstance().getSigner(PIN, cert));

// upgrade to T
signature.upgrade(SignatureType.ES_T);

signature.write(new FileOutputStream(BASE_DIR + SIGNATURE_FILENAME));

C signature creation is as follows:

The difference is the upgrade line, which is ES_C in this case.

// upgrade to C
signature.upgrade(SignatureType.ES_C);

X1 signature creation is as follows:

The difference is the upgrade line, which is ES_X_Type1 in this case.

// upgrade to X1
signature.upgrade(SignatureType.ES_X_Type1);

X2 signature creation is as follows.

The difference is the upgrade line, which is ES_X_Type2 in this case.

// upgrade to X2
signature.upgrade(SignatureType.ES_X_Type2);

XL signature creation is as follows:

The difference is the upgrade line, which is ES_XL in this case.

// upgrade to XL
signature.upgrade(SignatureType.ES_XL);

A signature creation is as follows:

The difference is the upgrade line, which is ES_A in this case.

// upgrade to A
signature.upgrade(SignatureType.ES_A);
