 This section defines the "https://iana.org/assignments/http-problem-types#digest-mismatching-value" problem type. A server MAY use this problem type when responding to a request, whose integrity fields include a digest value that does not match the digest value that the server calculated for the request content or representation.

 Three problem type extension members are defined, which SHOULD be populated for all responses using this problem type:
 
 - The `algorithm` extension member is the algorithm key of the used hashing algorithm.
