Functions

func GenerateKey

func GenerateKey() (*ecdsa.PrivateKey, error)

GenerateKey generates a new ECDSA private key for the P-256 curve

func GenerateSharedKey

func GenerateSharedKey(publicKey *ecdsa.PublicKey, privateKey *ecdsa.PrivateKey) ([]byte, error)

GenerateSharedKey generates a shared key using ECDH exchange between a public and private key

func MarshalPrivateKey

func MarshalPrivateKey(privateKey *ecdsa.PrivateKey) ([]byte, error)

MarshalPrivateKey marshals a private key to SEC 1, ASN.1 DER form
