Description

We currently make extensive use of SHA256, which is hard-coded in many parts of the codebase. We should make this user-configurable and offer e.g. SHA512 and SHA3.

Research direction

Start by searching the repository for hard-coded SHA256 usage and map which components depend on it. Read the surrounding digest and configuration paths to determine the scope of a user-configurable algorithm choice. Done means the supported algorithms and configuration behavior are defined and implemented consistently across those uses, with coverage for SHA512 and SHA3.
