Hi All,
Since version 0.9.62 libmicrohttpd appears to be started adding optional
"algorithm" field for digest authentication header. According to RFC2617
https://datatracker.ietf.org/doc/html/rfc2617
<https://datatracker.ietf.org/doc/html/rfc2617> and RFC7616
https://datatracker.ietf.org/doc/html/rfc7616
<https://datatracker.ietf.org/doc/html/rfc7616> the algorithm value is
case-sensitive (no explicit definition, as for “stale” field) and should be
"MD5" (uppercase) if MD5 is selected, but libmicrohttpd sets as "md5"
(lowercase). The case difference makes some client libraries to fail detecting
digest authentication presence from server responses.
From RFC2617:
algorithm
A string indicating a pair of algorithms used to produce the digest
and a checksum. If this is not present it is assumed to be "MD5”.
From RFC7616:
algorithm
A string indicating an algorithm used to produce the digest and an
unkeyed digest. If this is not present, it is assumed to be
“MD5"
Best regards,
