i was reading the article, http://www.f-secure.com/weblog/archives/00001293.html
but just an example.
why do many people out there think password hash "can't be" as good as
the password itself and needs to be computed/cracked first before it
can be used?
Consider the fact, many websites/forums don't use password hash+salt,
just password hash( generally SHA1, MD5) that gets computer client
side and POSTED to the web-forum for user authentication.
If someone can sniff this, given that, user name is available using
simple GUI tools as 'Tamper Data' ( firefox plug in ) even a low tech
malicious user can log on with someones credentials without having to
crack the password hash, instead just using the password hash itself
manipulating the POST request.
makes sense? :)
