Description: collection of cryptographic functions that support every js runtime for ES5+
Author: Harmonic Laboratories
Latest version: 0.3.0

# @harmoniclabs/crypto

collection of cryptographic functions that support every js runtime for ES5+

## Disclaimer

The purpose of the library is to guarantee support for any javascript runtime with ES5+.

**THIS IMPLEMENTATION SHOULD NOT BE ASSUMED TO BE SAFE**

If you are in a node js environment you should use the [node crypto native module](https://nodejs.org/api/crypto.html); without doubt more preformant and secure.

## vrf batch verification benchmarks

> NOTE: for batches with 38 elements or more the pippenger multiscalar multiplication should be used
> 
> however it seems that there is something wrong wiht the implementation;
> since pippenger returns false where instead straus returns true (as it should be);
>
> for now then all batches sizes do use the straus algorithm, which is not optimal
>
> as you can see from the benchmarks, after size 32, the time/proof flattens
> (or get even worse in the case of bun)
