How can I create XAdES-T signature for binary content with xades4j?

Question

I want to create detached XAdES-T signature for binary files. I've found in an other stack overflow post the xades4j tool. But I've found only examples for creating signature for xml documents. How can I sign binary file with xades4j?

Answer 1

You have different options to setup the signed data objects depending on you scenario. Check out the xades4j wiki on GitHub:

• https://github.com/luisgoncalves/xades4j/wiki/DefiningSignedResources
• https://github.com/luisgoncalves/xades4j/wiki/SignatureTypes#detached-signatures-over-non-xml-resources

Also, Apache XML Security (the foundation for xades4j) supports file: URIs, so you might also use this along with specifying the base URI.
