/**
A cryptographic digest as a multibase-encoded multihash — the encoding the W3C Verifiable Credentials Data Model 2.0 defines for `digestMultibase`, and the one `did:webvh` uses for its SCID and entry hashes.
Multihash carries the hash algorithm in-band, so the value is self-describing and the wire format survives an algorithm change without a schema revision; multibase does the same for the base encoding, so a verifier never infers base58 from base64url by context. A bare hex string or a `sha-256:`-style prefix hard-codes one algorithm into the wire contract and is non-conforming here.
This definition constrains the *encoding only*. What the digest is computed over is stated by each referencing field, because it differs legitimately: a digest over a JSON document is taken over its RFC 8785 (JCS) canonicalization, while a digest over an opaque artifact is taken over its bytes. A field whose input is a JSON document and which does not name a canonicalization is not reproducible.
Restricted to the two multibase headers W3C Controlled Identifiers 1.0 §2.4 normatively requires — `z` (base58btc) and `u` (base64url-no-pad). CID permits others but states that "interoperability is not guaranteed between implementations using such values", and a registry whose purpose is interoperability should not mint digests a conforming verifier may be unable to read. The alphabets are enforced rather than assumed: base58btc excludes 0, O, I and l, and an earlier permissive pattern let three published examples carry digests that were not valid base58 at all. base58btc is RECOMMENDED, for consistency with `did:key` and `did:webvh`.*/
