Thank you Antoine for your reply. I am able to access the artifacts from Maven repository now.
I am trying to implement the following Collective Signature algorithm for my academic project: https://tools.ietf.org/id/draft-ford-cfrg-cosi-00.html I found a sample implementation on github: https://github.com/jpopesculian/ed25519-cosi https://github.com/jpopesculian/ed25519-cosi/blob/master/ed25519_cosi.c The sample implementation accesses following functions which are at package visibility in Tuweni: crypto_core_ed25519_add The implementation also tries to access the following functions and I could not find them in Tuweni crypto: crypto_core_ed25519_scalar_reduce crypto_scalarmult_ed25519_base_noclamp Could you please confirm whether Tuweni has support for the above functions and also whether it would be a good idea to access low level APIs? Thanks, Richards Peter.
