Gabi is a Go implementation of the IRMA approach to the Idemix attribute based credential system. Check out the IRMA website to learn more on this great alternative to traditional identity management.

gabi itself is designed to be compatible with the existing Java and C++ implementations of the IRMA system.

Do note that this library is still fairly young. As such there might be some API-changes in the near future. And although most (if not all) cryptographic primitives are present, it does need additional "field testing". In addition, since this library implements (non-trivial) cryptography it needs to be checked by many more eyeballs.
