Wikipedia claims key length can be very big in this cipher, so I assume it can offer a million bits of security provided entropy of key is the same?
Of course I can SHA-256 hash the key to allow any key sizes for AES... but it defeats the whole purpose of having such large entropy when the security is less.
So what is the maximum level? For instance, AES-256 provides a 256 bit security level. I don't want it to wrap the keys or diminish its security/entropy.
Wikipedia and most sources are not clear about it.
