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.

Return Values

The mbx\_x25519_public_key function returns the status that indicates whether the operation completed successfully or not. The status value of 0 indicates that all operations completed successfully. The error condition can be analyzed by the MBX_GET_STS() call.
