Recover Public Key From Signed Message

xcthulhu opened this issue · comments

A standard utility is a function for recovering a public key from a signed message.

See, for instance, https://github.com/ethereum/ethereumj/blob/80be70c3428f244706c6fc6ac67e1bd5374eeb05/ethereumj-core/src/main/java/org/ethereum/crypto/ECKey.java#L527

Okay, it doesn't look like the elliptic package supports this :(

Maybe someday I'll shave that yak, but for now not so much...
