Struct CanisterMasterKey 

pub struct CanisterMasterKey { /* private fields */ }

The canister’s master public key of a threshold signature system

Each canister gets its own canister master key, which is derived from the system master key.

Implementations

impl CanisterMasterKey

pub fn derive_key_with_context(&self, context: &[u8]) -> DerivedPublicKey

Derive the public key from a canister key and a single contextual input

VetKeys requires exactly one contextual input be supplied. In addition, if that contextual input is the empty bytestring then the “derived key” is identical to the canister master public key. This matches the behavior of the management canister interface.

For other keys, which support a path of inputs, this is equivalent to deriving using a path of length 1

pub fn derive_key(&self, path: &[Vec<u8>]) -> Result<DerivedPublicKey, Error>

Derive a public key using a path of contextual inputs

Note that VetKD does not support derivation paths, but only a single context string, so VetKD is not supported by this function.

pub fn serialize(&self) -> Vec<u8>

Return the serialized encoding of the canister master public key

pub fn chain_code(&self) -> Option<Vec<u8>>

Return the chain code used for further derivation, if relevant

Returns None if not applicable for this algorithm
