And if you're generating your one time pads using a (hopefully cryptographically-secure) pseudorandom number generator, then congratulations! You are literally reinventing a stream cipher except with enormous, non-reusable keys.
- ekyepyaport 11y agonon-reusable keys! what a critique on one time pads! and enormous keys too! you might need to store them on some sort of notebook or large paper thingie!
- snaily 11y agoThe point is that the desire to use a OTP typically hinges on it being "uncrackable". By using a PRNG (even if it is a cryptographic stream cipher) to generate your pad, you've just re-introduced the same "crackability" (by way of the PRNG), and your system is strictly worse (same security, worse logistics) than an existing system.
