hi list,
i was reading the article, http://www.f-

but just an example.

blah blah blah, this is full-disclosure not some dear diary/myspace
bullshit,

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?

dunno why don't you tell me?

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.

done

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? :)

no please clarify!!!

thanks,
-bipin
