as BASIC were pwd is transmitted near clear text (B64enc). This has some implication as RFC 2617 requires and recommends a password hash MD5(user:realm:pwd) for DIGEST. !!! before activating DIGEST you have to reassign all passwords !!! to allow new calculation of the hash - default authentication is still BASIC - configuration at this time only manually in (DATA/settings) or defaults/web.xml (<auth-method> - the realmname is in defaults/yacy.init adminRealm=YaCy-AdminUI - fyi: the realmname is shown on login screen - changing the realm name invalidates all passwords - but for security you are encouraged to do so (as localhostadmin) - implemented to support both, old hashes for BASIC and new hashes for BASIC and DIGEST - to differentiate old / new hash the in Jetty used hash-prefix "MD5:" is used for new pwd-hashes ( "MD5:hash" )
