The soft factor.exe is join to crack all the EncryptedChat V2 packets Neuralabyss Software claim to use RSA encryption ( with a logo in the soft ) in his internet chat soft : Encrypted Chat V2 can be found here : http://www.users.bigpond.com/annex31/Downloads/index.html I've installed a LAN sniffer on my LAN and i found two packets to exchange the key ( it seem to be prime numbers ): COMPUTER 1 send to computer 2, one packet with this inside : 110358302195623472832716817864879473 // 1679255177848752162851143387478689891 The // are in the packet. ( two numbers in each packet ) Could someone tell me if they are prime ? COMPUTER 2 send to computer 1, one packet with this inside : 1935778852695641963616421814534998273 :: 3294171656609397704278174186334516191 The :: are in the packet Are these two numbers prime ? If i disconnect and reconnect the numbers will be always different After this packet exchange the data are encrypted with an unknown algorithm The problem that each prime number seem to have ONLY 122 bits !!! If it's correct and if RSA is used, then EncryptedChat V2 is dead !! Neuralabyss Software has others crypto soft on his web site : SecurePad and dozeCrypt, but i think if EncryptedChat has a backdoor, the other softs have backdoors too !
