Due to changes in math which were not accompanied with a version change, some tests in Clarc are broken.
Specifically, the changes to representations which were introduced with math commit 3584fba84dd224323e95792f156cde6b45cb0ec1 changed the way, for example, the ZnAdditiveGroup was serialized from an ObjectRepresentation to a RepresentableRepresentation.
These issues are fixed by using the upb.crypto.math version from commit 0430de8a079af16c1ea9f5d9772b222dbffe57ce .

Furthermore, the de.upb.crypto.clarc.acs.protocols.impl.clarc.provecred.Witness class did not have a StandaloneParameter defined for the GenericStandaloneTest which meant it was initialized with a instance set to null, causing that test to fail.
I fixed this by excluding the Witness class from that test for now. It does not have a public constructor anyway, so it would be difficult to add it in any case.

Hi upb.crypto team. I am very interested in this library and its applications. Could you please give me source code of your example application which is mentioned in section 6.7 of the project's document?

Hi, I'm trying to run the CLARC benchmarks but it seems to be slower than expected given Table 3 in the paper..

For example, I'm getting that it took ~18s, 763ms to verify (5 in Table 3) when it should be taking ~0s, 170 ms.

For context, I'm running on a 2019 MacBook pro:
./gradlew test --tests de.upb.crypto.clarc.acs.PerformanceTest

Any ideas for what could be going wrong here?

Thanks!
