  • Use Ruby to Generate your Shadow Password

    |

    I was initially stumbled on creating the shadow compatible SHA-512 hash. After a little research, the answer was obvious: require ‘digest/sha2’ password = “pass@123” salt = rand(36**8).to_s(36) shadow_hash = password.crypt(“$6$” + salt) And you now have a password hash which you can directly use in /etc/shadow

  • SEED hits the pit again #iknowvention

    SEED continues to make mistakes. So is today’s challenge: #include int main(int argc, char *argv[]) { printf(“%d”,4[“seed”]); return 0; } The answer for the above is 0, as the fourth element in the array “seed” does not exist. This is because of the index value, which starts from 0. Had it been 3, then it…
