That's the whole point of OTP as an imaginary construction!
It's a way to take any block cipher and turn it into a stream cipher with the power of XOR.
(I'm only going to ask this nicely once: cease and desist stalking and harassment.)
- tptacek 12y agoNo, you have your terminology thoroughly confused. An OTP is an information-theoretically secure cipher where the key is as long as the plaintext. The only relationship between a one-time pad and CTR is the XOR operation. Furthermore, the article you're responding to explains what's wrong with simple stream ciphers for disk sector encryption.
