Adding Info to the keyInfo node

[brugambwa]

How would one achieve such an output of the signature tag with this API?

EDIT: The first reference and the digest is calculated on the KeyInfo tag, which is added using the getKeyInfoContent. So the addReference cannot find the reference to the KeyInfo tag as it's not part of the initial XML. Is there an implementation I could use/change in the library to be able to produce the output below?

I'm not sure which API you're referring to, but you can replace the getKeyInfoContent() function with your own implementation. I would imagine that would do what you need. If the documentation is unclear about that, feel free to submit a PR with updated documentation.

I meant the xml-crypto library not API, sorry. I need to add a reference to content added by getKeyInfoContent() and compute a digest for that tag and all it's contents.
