An implementation of the Groth-Sahai NIZK protocol
⚠ Warning ⚠
This is an experimental library and is only at its first version. The API could still be updated in the near future. I cannot guarantee the security of this library, and one should not use this in production.
- Install PBC on your machine (Hopefully we can solve this in time)
- Setup a shared library
- mvn clean test
