Involved Source Files Package entropy provides the passive entropy source for the FIPS 140-3 module. It is only used in FIPS mode by [crypto/internal/fips140/drbg.Read]. This complies with IG 9.3.A, Additional Comment 12, which until January 1, 2026 allows new modules to meet an [earlier version] of Resolution 2(b): "A software module that contains an approved DRBG that receives a LOAD command (or its logical equivalent) with entropy obtained from [...] inside the physical perimeter of the operational environment of the module [...]." Distributions that have their own SP 800-90B entropy source should replace this package with their own implementation.
Package-Level Functions (only one)
Depleted notifies the entropy source that the entropy in the module is "depleted" and provides the callback for the LOAD command.
