From there, the algorithm calculates the _S_ value of the signature, such that:
_S_ = __k__^-1^ (__Hash__(__m__) + __dA__ * __R__) _mod p_

* _R_ is the x coordinate of the ephemeral public key
* _dA_ is the signing private key
* _m_ is the transaction data
* _p_ is the prime order of the elliptic curve
* _n_ is the prime order of the elliptic curve
Verification is the inverse of the signature generation function, using the _R_, _S_ values and the public key to calculate a value _P_, which is a point on the elliptic curve (the ephemeral public key used in signature creation):
