Golang crypto/elliptic.Unmarshal() function example

package crypto/elliptic

Unmarshal converts a point, serialized by Marshal, into an x, y pair. On error, x = nil.

Golang crypto/elliptic.Unmarshal() function usage example

 var marshaled []byte
 marshaled = elliptic.Marshal(elliptic.P224(), x, y)

 fmt.Printf("Point : %x\n", marshaled)
 fmt.Println()

 var unmarX, unmarY *big.Int
 unmarX, unmarY = elliptic.Unmarshal(elliptic.P224(), marshaled)

 fmt.Printf("Unmarshaled X : %d\n Y : %d\n", unmarX, unmarY)
 fmt.Println()

Example output :

Point : 04f93bd2b06e3c0bb1......b812fe

Unmarshaled X : 262473703821.....691646499146372

Y : 2307843595856198227....859233022
