Functions

func CheckKey

func CheckKey(k key.Key) error

CheckKey checks whether the given key is a valid Ed25519 key.

func GenerateKey

func GenerateKey() (key.Key, error)

GenerateKey generates a new Key for Ed25519.

func KeyFromPrivate

func KeyFromPrivate(pk goed25519.PrivateKey) (key.Key, error)

KeyFromPrivate returns a private Key with given ed25519.PrivateKey.

func KeyFromPublic

func KeyFromPublic(pk goed25519.PublicKey) (key.Key, error)

KeyFromPublic returns a public Key with given ed25519.PublicKey.

func KeyFromSeed

func KeyFromSeed(seed []byte) (key.Key, error)

KeyFromSeed returns a private Key with given ed25519.PrivateKey seed.

func KeyToPrivate

func KeyToPrivate(k key.Key) (goed25519.PrivateKey, error)

KeyToPrivate returns a ed25519.PrivateKey from the given key.

func KeyToPublic

func KeyToPublic(k key.Key) (goed25519.PublicKey, error)

KeyToPublic returns a ed25519.PublicKey from the given key.

func NewSigner

func NewSigner(k key.Key) (key.Signer, error)

NewSigner creates a key.Signer for the given private key.

func NewVerifier

func NewVerifier(k key.Key) (key.Verifier, error)

NewVerifier creates a key.Verifier for the given key.

func ToPublicKey

func ToPublicKey(k key.Key) (key.Key, error)

ToPublicKey converts the given private key to a public key. If the key is already a public key, it is returned as-is.
