Hi,

I had reported this privately to Niels Möller, but I'm re-sending it here so it's publicly available and archived. (Niels didn't think it's neccesary to keep this private.)

The attached example will show a bug in the nistp256 point multiplication of nettle. It compiles a certain curve point with 1 which should not change the coordinates, however it does.

Was fixed here: https://git.lysator.liu.se/nettle/nettle/commit/c71d2c9d20eeebb985e3872e4550...
