private key should be non-hexed

[sarlongda]

When I use sign function you said the private key should be hexed private key with zero prefixed.
But If I input "0x....." private key, then this returns an error

@sarlongda

Is this issue related to #27?

That's weird, the 0x prefixed test passed.

After read through elliptic source code, I think the le mode can break 0x prefixed private.

I'm going to remove the 0x before generate private key.
