Projects: Ursa is currently the only crypto library in use for Indy-SDK (i.e., the Indy crypto library is no longer used in this case) and Indy maintainers and contributors are working towards using Ursa for all of their cryptography. We have also been recently notified that an intern has completed work on integrating Ursa into Iroha, which is more good news (this was done by the Iroha team, so they deserve the credit here–not us) (David Husebycan you add more here? Thanks!https://github.com/hyperledger/iroha/commit/b3adc310e9c797c9dd5c99e4a7b518f2c5cf50f0).
Questions/Issues for the TSC
...
- Anonymous Credentials: we have been formulating an implementation for anonymous credentials, which has gone through multiple iterations.
- Threshold issuance credentials: we plan to add these once we standardize an API.
New RFCs:
- Encryption API: we have built an API for modular (symmetric) encryption. This will allow us to "plug and play" symmetric key encryption protocols and block ciphers once implemented.
- Delegatable credentials and z-mix are in the pipeline.
New Code:
- Camenisch-Schoup Verifiable Encryption:
- Pointcheval-Sanders (PS) signatures:
- Much more "in the pipeline."
Current Plans
We have a lot of work in progress, both in our base crypto library and in our zero knowledge-focused zmix library. Some things include:
