Types

type DecryptionKey

type DecryptionKey struct {
	// contains filtered or unexported fields
}

DecryptionKey is a private key wrapper that can perform decryption.

func FromPrivKey

func FromPrivKey(sk crypto.PrivKey) (*DecryptionKey, error)

FromPrivKey returns a key by parsing k into a private key.

func (*DecryptionKey) Decrypt

func (k *DecryptionKey) Decrypt(ciphertext []byte) ([]byte, error)

Decrypt ciphertext with a private key.

func (*DecryptionKey) Encrypt

func (k *DecryptionKey) Encrypt(plaintext []byte) ([]byte, error)

Encrypt bytes with a public key.

func (*DecryptionKey) MarshalBinary

func (k *DecryptionKey) MarshalBinary() ([]byte, error)

MarshalBinary implements BinaryMarshaler.

type EncryptionKey

type EncryptionKey struct {
	// contains filtered or unexported fields
}

EncryptionKey is a public key wrapper that can perform encryption.

func FromPubKey

func FromPubKey(pk crypto.PubKey) (*EncryptionKey, error)

FromPubKey returns a key by parsing k into a public key.

func (*EncryptionKey) Encrypt

func (k *EncryptionKey) Encrypt(plaintext []byte) ([]byte, error)

Encrypt bytes with a public key.

func (*EncryptionKey) MarshalBinary

func (k *EncryptionKey) MarshalBinary() ([]byte, error)

MarshalBinary implements BinaryMarshaler.
