Explain why, please. It might expand the attack surface, that's true. You
could always add a signed message that says "I used a key named 'Z' for

Use of a key for one makes the other incompatible.�
Incorrect. One's public key is always an elliptic point, one's private
key is always a number.
Thus there is no reason

Hi!
I made a simple elliptic curve utility in command line PHP:
https://github.com/LaySoft/ecc_phgp
I know in the RSA, the sign is inverse operation of encrypt, so two
different keypairs needs for encrypt and sign. In elliptic curve
cryptography, the sign is not the inverse operation of encrypt,
