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

Package Exports

  • @harmoniclabs/crypto
  • @harmoniclabs/crypto/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@harmoniclabs/crypto) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@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; 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)

NOTE: bun performs better in basically all cryptography functions except for this specific batch vrf.
