anybody?

(in my first presentation is 0 <= 4 <= 4-x^2 ) sorry about that

but it seems it have maximals in x € [0,2], y = 4 - x
kiBytes
Oct 5, 2014 18:43
from my point of view, I thought that it should have only one maximal element in x=0, y = 4

c = { (x,y) € R^2 | 0 < y < 4 - x^2 }

(I mean entropy for salt)
kiBytes
Apr 23, 2014 15:11
Does the entropy here simply help us to have some sort of "unique" hashes across internet?
kiBytes
Apr 23, 2014 15:11
So, maybe the true question is, why is entropy so important? isn't it enough to have unique salts.
kiBytes
Apr 23, 2014 15:09
@CodesInChaos yeps that is very true, that what I thought with the rainbow tables... On the other way, if you use the pair you have suggested "server", "username"... Although some server have very long names
kiBytes
Apr 23, 2014 15:01
@CodesInChaos yes but, In my previous thoughts I thought that once cracked a system, probably the user will be using the same password so a different hashing didn't seem to add more strength here...
kiBytes
Apr 23, 2014 14:57
so I guess that is a good reason...
kiBytes
Apr 23, 2014 14:57
just giving a different perspective now I am thinking about rainbow tables will use common usernames to generate the hashes
kiBytes
Apr 23, 2014 14:55
(I know that the entropy is also way lower than a random generated pass, but again... )
kiBytes
Apr 23, 2014 14:54
any thoughts?
kiBytes
Apr 23, 2014 14:54
I know that it would be a well known salt, but I don't know if that means to be a bad salt...
kiBytes
Apr 23, 2014 14:53
@ThomasPornin (or any other), yesterday I was thinking about why the hell couldn't we use the username as a salt for hashing the password, after all, usually the username is unique...

Q: Use SSH config file with Putty

Sam RadI'm using SourceTree (a Git GUI) which uses Putty as SSH client. I need to push some code into a repository for which I need to tunnel through SSH to do so. The trouble is, the repository and SSH authentication server are on separate servers. Hence, I need to login to one server and then push to ...

authentication windows ssh configuration
