30.1.2.5 Counter (CTR) Cipher Mode
In counter mode, a random 128-bit initial counter value is incremented modulo 2
processed. The modulus size can be set between 2
The running counter is encrypted and XOR’d with the plaintext to derive the ciphertext, or with
the ciphertext to recover the plaintext as shown in
