var ErrInvalidKeySize = errors.New("invalid key size")

ErrInvalidKeySize is error that is returned when key has invalid size.

Functions ¶

func GenerateKeys ¶

func GenerateKeys() (PrivateKey, PublicKey, error)

GenerateKeys generates a pair of PrivateKey and PublicKey.

Types ¶

type PrivateKey ¶

type PrivateKey []byte

PrivateKey is a private key used for signing.

func (PrivateKey) Sign ¶

func (k PrivateKey) Sign(data io.Reader) (Signature, error)

Sign signs data hash with PrivateKey.

func (PrivateKey) Size ¶

func (k PrivateKey) Size() int

Size returns the size of PrivateKey.

type PublicKey ¶

type PublicKey []byte

PublicKey is a public key used for signature verification.

func (PublicKey) Size ¶

func (k PublicKey) Size() int

Size returns the size of PublicKey.

func (PublicKey) Verify ¶

func (k PublicKey) Verify(s Signature, data io.Reader) (bool, error)

Verify verifies that Signature is a valid signature of data by PublicKey.

type Signature ¶

type Signature []byte

Signature is a data hash signed with PrivateKey.

func (Signature) Equals ¶

func (s Signature) Equals(ss Signature) bool

Equals checks if two signatures are equal.

func (Signature) Size ¶

func (s Signature) Size() int

Size returns the size of Signature.
