The Digest scheme challenges using a nonce value. A valid response contains a checksum (by default, the MD5 checksum) of the username, the password, the given nonce value, the HTTP method, and the requested URI. In this way, the password is never sent in the clear. Just as with the Basic scheme, the username and password must be prearranged in some fashion not addressed by this document."""@en ; skos:notation "urn:ogc:def:security:authentication:ietf:2617:Digest" ; skos:prefLabel "HTTP_DIGEST"@en .
