Local keystore implementation. This file is from substrate but was copied here to have access to the private stuff. Original file: https://github.com/paritytech/polkadot-sdk/blob/76a6d478e07b2cdf9e5b87a2a840e92bea8d9e12/substrate/client/keystore/src/local.rs

ac_keystore

This crate is a submodule of the substrate-api-client. It is a fork of substrate's sc-keystore crate. The substrate-api-client needs its own fork in order to access private functions and members of the crate.
