whaaaaaaat - taking a 512-bit hash and truncating it to 256 preserves everything you need about it! That's crazy (surprising). Naively - if you hadn't just told me otherwise - I'd think it's up there with my brilliant new algorithm: in a loop pad your input with 0x00 through 0xFF, take the SHA512 hash of each result, but only use the first bit! You now have a sooper secure 256 bit hash. I call it SHA512/1/1/.../1 (I'd write it all out here, but it looks obnoxious and might break someone's window width.) |
