ic-pub-key
The Internet Computer protocol offers a number of threshold signature schemes to canisters running on the system. The public keys which are used to verify these signatures are derived from a single master public key using a deterministic scheme which includes the canister's identifier as well as any canister-provided context data.
This derivation can be performed "online" by a canister using a query call, but this is inconvenient in some usage scenarios. This crate offers an alternative, namely fully offline key derivation.
