Creates a Signify Controller starting at key index 0 that generates keys in memory based on the provided seed, or bran, the tier, and the rotation index.
The rotation index is used as follows:
Digests of the next public keys formatted in fully-qualified Base64.
The rotation index used during key generation by this Controller.
The salter is a cryptographic salt used to derive the controller's cryptographic key pairs and is deterministically derived from the bran and the security tier.
Either the current establishment event, inception or rotation, or the interaction event used for delegation approval.
The current signing key used to sign requests for this controller.
The stem is the prefix for the stretched input bytes the controller's cryptographic key pairs are derived from.
The security tier for the identifiers created by this Controller.
Controller is responsible for managing signing keys for the client and agent. The client signing key represents the Account for the client on the agent
