yoyois Posted March 20, 2017 Report Posted March 20, 2017 (edited) Am nevoie de niste data-points in legatura cu abilitatea unui individ de a sparge un hash. Trebuie sa gasesc o cheie suficient de scurta incat sa poate fi sparta usor(in 24-48 h) dar suficient de sigura incat sa poata asigura securitatea pt cel putin 6-10h. Luati treaba ca un challenge si postati, daca incercati timpul in care ati spart cheia, hardware-ul folosit(daca vreti) si eventual ce soft, metoda, heuristici. (sau ce probleme ati intampinat) (vreau sa observ si scara in care creste timpul de crack in comparatie cu cheia) MD5, 4 small letters a-z : 92cd8d45130b33c5461f6c4ebc8fa8f3 MD5, 5 small letters a-z : c80a60e335f0451349bffe77d61f0b1b MD5, 6 small letters a-z : f70e537a7a8397d3b8e43e3026ea8824 MD5(MD5), 6 small letters a-z : 6cbf7131b2b73859ecb7925b64d8b9e6 MD5, 5 small letters a-z + last one is a number 0-9 : 85b0fc46a8eee36b530fbccfe1676891 Step up your game MD5, 7 small letters a-z : 31ec1bc10fee2c86270b3bf547c0d416 MD5, 7 small letters a-z + 1 digit 0-9: 44673da6f35229a3850fc08b26e77b09 MD5(MD5), 7 small letters a-z + 2 digits 0-9: 562ac68d5bc31d3764e65c3aa9281241 Edited March 20, 2017 by yoyois Quote
