-This is a [pairing cryptography](https://en.wikipedia.org/wiki/Pairing-based_cryptography) library written in pure Rust. It makes use of the Barreto-Naehrig (BN) curve construction from [[BCGTV13]](http://eprint.iacr.org/2013/507) to provide two cyclic groups **G<sub>1</sub>** and **G<sub>2</sub>**, with an efficient bilinear pairing:

+## Security warnings
+
+This library, like other pairing cryptography libraries implementing this construction, is not resistant to side-channel attacks.
