Yes, I merely want to reiterate as clearly as possible that there's no such algorithm endorsed by NIST. AES is a standard, AES-1024 isn't one of the variants of that standard. For good reason.
Symmetric key sizes larger than 256 bits are pretty much universally snake oil.
- a1369209993 5y ago> Symmetric key sizes larger than 256 bits are pretty much universally snake oil. 512, actually - some symmetric applications are vulnerable to collision or collision-like attacks, and a cosmological-scale attacker can theoretically get up to about 2^308[0] bit operations at current-ish cosmic microwave background temperatures, so 2^256 bit operations is just about plausible in worst case scenario planning. But 256-bit keys are probably sufficient for any practical application, and that doesn't excuse 1024 anyway. 0: You have: log2(1e80 amu c2 / k 3K ln(2)) # (mass of observable universe / landauer limit) Definition: 307.99542
