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.
