big endian save&load

[fionser]

Any (easy) way to change littlte endian to big endian when doing serialization.

[herumi]

Is it about Fp? There is no way to do so now.

@herumi Is the serialization format for BN, G1, G2, GT compatible with Relic? I'd like to move to MCL instead of relic but I need data to look as it is now. Is it possible to convert if not?

[herumi]

I don't know Relic's format. How do you convert it? Do you import the binary data exported from Relic to mcl?

[Scratch-net]

I don't convert it (yet) I just wanted to figure out if it's possible. I use functions g1_write_bin, g2_write_bin, etc

@Scratch-net
mcl supports Affine/Jacobi coordinate.
After generating (x, y) by Relic and could you set it to mcl?

[Scratch-net]

Haven't tried that, I need to check and get back to you.
