Nimcrypto is Nim's cryptographic library. It implements several popular cryptographic algorithms and their tests with some [examples](https://github.com/cheatfate/nimcrypto/tree/master/examples).
Most notably, this library has been used in the [Nimbus Ethereum client](https://our.status.im/nimbus-for-newbies/). To see the implementation, check out its [Github repository](https://github.com/status-im/nimbus).
