Bug #: 52515
Summary: Digest auth specifically requires digested passwords
to hashed with MD5
Product: Tomcat 7
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Documentation
AssignedTo: dev@tomcat.apache.org
ReportedBy: djpow...@djpowell.net
Classification: Unclassified
Re:
http://tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#Digested_Passwords
The documentation says:
"If using digested passwords with DIGEST authentication, the cleartext used to
generate the digest is different. In the examples above {cleartext-password}
must be replaced with {username}:{realm}:{cleartext-password}."
The documentation does not mention the fact that when using HTTP Digest Auth
with digested passwords, you MUST use the MD5 algorithm to digest the
passwords.
When the authentication is performed, the digest algorithm specified for the
realm is ignored, and MD5 is always used, so if SHA has been used,
authentication will fail.
(Would it be appropriate to log a warning if it is detected that Digest Auth is
being used and the Realm's digest algorithm is something other than MD5...?)
