PSA_PAKE_STEP_ZK_PUBLIC macro

A Schnorr NIZKP public key. This is the ephemeral public key in the Schnorr Non-Interactive Zero-Knowledge Proof (the value denoted by the letter 'V' in RFC 8235). The format for both input and output at this step is the same as for public keys on the group determined by the primitive (::psa_pake_primitive_t) would be. For more information on the format, consult the documentation of psa_export_public_key(). For information regarding how the group is determined, consult the documentation #PSA_PAKE_PRIMITIVE.
