Re: [tor-talk] New Software: P2P filesharing designed to use Tor



yes i have changed now to SHA-256 because it is said to be more secure, thank you.
Also i introduced a fourth Hash-level in the hash-tree (of 5k Blocks). They are only used now to build the higher level hashes, they are not transmitted. If needed, they can be transmitted also to do more fine grained validation.

@Aymeric Vitte
Thanks i have learned a lot now. I also saw that Tribler has published a warning that security has not yet matured.
I think file sharing of small files should work, for big files people should not use tor if they have other sources available.

Hey,
maybe I am paranoid, but could you implement an second hash computed
out of the file. SHA-256 would be perfect, because when you have
security in mind, NSA could break SHA-1. When you are using two hashing
algos than it is even harder to attack it.
