If you trust a one-time pad---which no one actually uses---you can trust stream ciphers, which are actually practical.

- im3w1l 10y agoThat doesn't follow at all...
- notfed 10y agoSure it does. A stream cipher is essentially the practical version of a one-time pad. Neither system is vulnerable to quantum attacks. For both, the weak link is in keeping the key secure. If you can keep a one-time pad secure, you can keep a 256-bit key secure.
