 This section defines the "https://iana.org/assignments/http-problem-types#digest-invalid-values" problem type. A server can use this problem type when responding to a request, whose integrity fields include a digest value that cannot be generated by the corresponding hashing algorithm. For example, if the digest value of the `sha-512` hashing algorithm is not 64 bytes long, it cannot be a valid SHA-512 digest value and the server can skip computing the digest value. This problem type MUST NOT be used if the server is not able to parse the integrity fields according to {{Section 4.5 of STRUCTURED-FIELDS}}, for example because of a syntax error in the field value.
