pub fn parse_multikey(raw: &str) -> Result<ParsedMultikey, IdentityError>Expand description
Parses a multikey string into a verifying key.
Accepts either a bare base58btc multibase string (z…) or a
did:key:z… form. The latter is how PLC audit logs and some DID
documents surface verification methods, so stripping the prefix here
means every caller can stay agnostic to the wire shape.
