subkey

Encryption's inner component

A subkey is a secondary key derived from or subordinate to a primary key.

In cryptography, subkeys are generated from a master key for use in specific rounds or operations of an encryption algorithm.

In databases and registries, a subkey is a key nested within another key, creating hierarchical organization: The setting is stored in a subkey under HKEY_CURRENT_USER.

In music, subkey can refer to a secondary or related key in a composition.
