Various Cryptographic Primitives in Sway for the Fuel VM

Testing for the different libraries is done in /testing. There are instructions in the separate testing folders.

For testing we use fuels, read about it here.

To run tests for bls folder:

cd testing/tests_bls12_381
forc test

You can use scripts locally to do intermediate tests. To run a script a local Fuel node must be spun up.

From here. In a separate tab in your terminal, spin up a local Fuel node:

fuel-core --db-type in-memory

This starts a Fuel node with a volatile database that will be cleared when shut down (good for testing purposes).

Make sure fuel-core is up to date. This can be done with fuelup. Also, make sure there's only 1 fuel-core installed (check this with which -a fuel-core).

For example in bls12_381/src create main.sw. Change in bls12_381/Forc.toml entry to main.sw.

Start the file with script; and whatever code is in fn main () { .. } will be executed with the following command:

forc run --unsigned --pretty-print

The --unsigned part is to avoid signing with a contract. The --pretty-print is for if you do some logging; it will get printed nicely.
