RFC 9901: REQUIRED. The base64url-encoded hash value over the Issuer-signed JWT and the selected Disclosures. The hash value in the sd_hash claim binds the KB-JWT to the specific SD-JWT. The sd_hash value MUST be computed over the US-ASCII bytes of the encoded SD-JWT, i.e., the Issuer-signed JWT, a tilde character, and zero or more Disclosures selected for presentation to the Verifier, each followed by a tilde character: <Issuer-signed JWT>~<Disclosure 1>~<Disclosure 2>~...~<Disclosure N>~ The bytes of the digest MUST then be base64url encoded.
