Crate ic_pub_key 

A crate for performing derivation of threshold public keys

The Internet Computer platform offers a threshold signing interface supporting ECDSA, Ed25519, BIP340-Schnorr, and BLS. The signing interface allows signing under many different keys which are derived from a master key using a derivation algorithm.

The management canister interface allows for online derivation of public keys: a canister running on the IC can invoke the call to determine what public key will be used for any particular context argument.

This crate mirrors that functionality in an offline way: it can be called either by canisters that do not wish to call the management canister interface, or by applications not running on that IC at all.

As an extension of the management canister interface, this crate also allows deriving keys relative to the hardcoded test master keys used by PocketIC.
