The hardest ECC scheme (publicly) broken to date had a 112-bit key for the prime field case and a 109-bit key for the binary field case. So 64-bit obviously won't do and at the same time it's a long way until 512-bit keys will be needed, if ever.

I meant we could use four 64-bit numbers to represent 256 bits. Regarding the long way until 512-bit keys will be needed - I want to implement RSA with 4096 bits.

Edit: Not everyone has hardware with AVX support, why not 128 bits at least/most?
