MD5 will always output a base-16 number, so the criteria it could meet does not change one bit when you scramble the value first. If you are going to brute force MD5, you have to start from 0000000.... and end at ffffff... because the values are not reversible and near values do not resemble each other ("hello" and "Hello." are completely different).
How is there a bigger risk if collision with a simple salt? |
