orignal going to do the same tommorow ))
zzz the header decryption stuff is where we really see how this is going to work
zzz I'm already seeing some problems
zzz about 3000 lines of code in so far
orignal zzz, why do you say XK Noise is different than in NTCP2?
orignal I don't see a difference
zzz the initialization string is different
orignal Noise_XKaesobfse+hs2+hs3_25519_ChaChaPoly_SHA256
orignal got i
zzz oops, it's wrong in one place, right in the other
zzz Set protocol_name = "Noise_XKchaobfse+hs1+hs2+hs3_25519_ChaChaPoly_SHA256"
orignal I see now
orignal the difference
zzz no, it's the same in both
zzz both places
orignal I copied from NTCP2
orignal but SSU2 adds hs1
zzz right, we're mixHashing the headers before each message, 1 2 and 3. NTCP2 mixHashes the padding after message 1 and 2
orignal thanks
orignal will chnage it
orignal also do you have sha256 of this string?
orignal I believe you calculated it already
zzz padding for every message is in the payload, since we know the total length
zzz not like NTCP2 where we have fixed message length for messages 1 and 2
zzz so the mixhash is more like ratchet
zzz I haven't logged it yet
zzz it's in a static initializer
zzz sha256generator "Noise_XKchaobfse+hs1+hs2+hs3_25519_ChaChaPoly_SHA256"
zzz sTcigXQjqP30LfLmDtHt9BuTBx2x7CSjZ~eE7CcNgTI=
orignal I need as array of hex bytes
orignal and will check
zzz echo -n "Noise_XKchaobfse+hs1+hs2+hs3_25519_ChaChaPoly_SHA256" | sha256sum
zzz b13722817423a8fdf42df2e60ed1edf41b93071db1ec24a367f784ec270d8132 -
orignal thanks
orignal and we also need one more
orignal sha256
zzz yup
