Actually such a thing is a critical security issue, as there are actually existing attacks on elliptic curves when using a point which is not on the elliptic curves. You could do twist attacks and creating smaller subgroups to determine the secret key.

https://cryptodeeptech.ru/twist-attack/

When running a Twist Attack , the “private key” can be obtained by a certain choice of the “public key” (selected point of the secp256k1 elliptic curve), that is, the value in the transaction is revealed.After that, information about the private key will also be revealed, but for this you need to perform several ECC operations.

@nodejs/security

I am not certain there is an issue since the actual use of the keys created this way will result in a) ECDSA verify false b) ECDH failing. I believe this check is merely a fail-fast mechanism.

It was important to talk about it. If openssl throws anyway, we are on the safe side.
