Use when adding or touching any hashing, checksums, base64, percent-encoding / URL escaping, or request signing (HMAC, Azure Shared-Key / SAS, token hashing) in the pocopine workspace. Routes the work through the shared pocopine-crypto and pocopine-codec crates instead of pulling in sha2 / md-5 / crc32c / hmac / base64 / percent-encoding directly or hand-rolling encoders.
