Parameters
pa_public_key
Array of pointers to the vectors of computed public key x-coordinates.
pa_private_key
Array of pointers to the vectors of private keys.
Description
This function computes x-coordinates only of pubic keys using private keys specified by
pa_private_key
parameter. Any 256-bit vector is applicable as a private key. Each vector must be at least 32-byte length to store the computed x-coordinate of the public key.
