Types ¶
type ED25519 ¶
type ED25519 struct {
// contains filtered or unexported fields
}
func (ED25519) EphemeralKey ¶
func (kx ED25519) EphemeralKey() (crypto.PrivateKey, error)
func (ED25519) SharedSecret ¶
func (kx ED25519) SharedSecret(privateKey crypto.PrivateKey, publicKey crypto.PublicKey) ([]byte, error)
SharedSecret computes a secret value from a private / public key pair. On sending a message the private key should be an ephemeralKey or generated private key, the public key is the recipient public key. On reading a message the private key is the recipient private key, the public key is the ephemeralKey or generated public key.
type SECP256K1 ¶
type SECP256K1 struct {
// contains filtered or unexported fields
}
func (SECP256K1) EphemeralKey ¶
func (kx SECP256K1) EphemeralKey() (crypto.PrivateKey, error)
func (SECP256K1) SharedSecret ¶
func (kx SECP256K1) SharedSecret(privateKey crypto.PrivateKey, publicKey crypto.PublicKey) ([]byte, error)
SharedSecret computes a secret value from a private / public key pair. On sending a message the private key should be an ephemeralKey or generated private key, the public key is the recipient public key. On reading a message the private key is the recipient private key, the public key is the ephemeralKey or generated public key.
type SR25519 ¶
type SR25519 struct {
// contains filtered or unexported fields
}
func (SR25519) EphemeralKey ¶
func (kx SR25519) EphemeralKey() (crypto.PrivateKey, error)
func (SR25519) SharedSecret ¶
func (kx SR25519) SharedSecret(privateKey crypto.PrivateKey, publicKey crypto.PublicKey) ([]byte, error)
SharedSecret computes a secret value from a private / public key pair. On sending a message the private key should be an ephemeralKey or generated private key, the public key is the recipient public key. On reading a message the private key is the recipient private key, the public key is the ephemeralKey or generated public key.
