Most users tipically use the same password for multiple applications. Let's say all of these applications hash the password in some way. Would it be easier for an attacker to get the original password if it got access to all the different hashes? Of course the attacker probably looking at the hashes may know which is the weaker one and only try to bruteforce this, but has he gained anything having access to other hashes of the same password? Also assuming the attacker does not have any rainbow table containing any of these hashes.
So, if an attacker has access to all these hashes of the same password, can he be faster in breaking it than just try to bruteforce one of the md5 hashes (as in this case is the weaker link)?
btw, the original password is
hello12345world12345, I'm not trying to (make you) crack someone's password ;-)
