  5. Regarding the key splitting… though this looks like an increase in security, in fact it actually decreases security because it drastically lowers the number of pk possibilities (from 2^256 to 2^128, many orders of magnitude smaller), meaning brute force attacks become more easily accomplished. In addition, dividing your key into two means that now you have twice the odds that an attacker can obtain one.
