Feat: adding Proof Configuration to Signature

[koptan]

Description

PR to include the proof configuration in the final hash during the process of creating and verifying the proof.

Therefore, the verification process should fail if any values in the Proof Configuration attributes change.

This PR should fix #34, also it's merge #38

@DominikPinsel @matgnt @borisrizov-zf @bjoern-arnold, please for your review.

I would leave this to the others to review. I'm not a Java developer and don't know the libraries internal structure.

[DominikPinsel]

I like the idea with the new ProofSignature objects :)

[borisrizov-zf]

@koptan you should rebase, because of #44

[koptan]

@borisrizov-zf Rebase is done, you can merge it 👍

[borisrizov-zf]

Please re-check your PR, the copyright year seems to be wrong on multiple files. Also method documentation has been removed, but it is essential to have documentation to be Maven Central compliant.
I'll re-do the review after these issues have been fixed.

@koptan Hi, still many more files have the docs deleted, and the copyright year is not 2024. I haven't marked them explicitly, due to the sheer quantity of files. Please review them and fix these issues, before I can continue.

@koptan can you point me in the right direction about the following:

verification method can be either a multibase string or a map, but I cannot see where transformation is taking place. The interface which binds these seems to be missing the option to easily extend to something like publicKeyJWK with an EC cipher. Am I missing something?

[koptan]

@borisrizov-zf transformation is happening in TransformedLinkedData, we accept any JsonLD object as parameter.

@koptan Hi, the branch needs rebasing, you're out of sync with main.
