Functions ¶

func NewKey ¶

func NewKey() *[32]byte

NewKey generates a new random 32 byte key

func Pubkey ¶

func Pubkey(seckey *[32]byte) *[32]byte

Pubkey takes a secret key and perform a scalar base multiplication to obtain the public key

func SharedKey ¶

func SharedKey(peerPublic, mySecret *[32]byte) (shared, myPublic *[32]byte)

SharedKey takes a peer's public key and our own secret key to obtain a shared secret through elliptic-curve Diffie-Hellmann. If mySecret is nil, a random secret key will be generated and the ephemeral public key will be output in myPublic. The peer needs our public key to be able to obtain the shared secret.

func Shred ¶

func Shred(b *[32]byte)

Shred overwrites the contents of an *array with random data and then sets the pointer to nil in an attempt to clear secret data from memory
