Q: AES-CTR Mode, Predictability of Nonce

SomeRandomNPCI'm trying to rebuild AES-CTR mode and have some questions concerning the generation of the nounce. I've comonly seen the nonce be distributed like this $Nonce_{128\,bits} = IV_{64\,bits} \mathbin\Vert Counter_{64\,bits}$ where the IV is randomly generated foreach message and the Counter incremen...
