Classes

class DH d where

Typeclass for Diffie-Hellman key agreement.

Minimal complete definition

dhName, dhLength, dhGenKey, dhPerform, dhPubToBytes, dhBytesToPub, dhSecToBytes, dhBytesToPair, dhPubEq

Associated Types

data PublicKey d :: *

Represents a public key.

data SecretKey d :: *

Represents a secret key.

Methods

dhName :: proxy d -> ScrubbedBytes

Returns the name of the DH scheme. This is used when generating the handshake name.

dhLength :: proxy d -> Int

Returns the length of public keys for this DH scheme in bytes.

dhGenKey :: IO (KeyPair d)

Generates a KeyPair.

dhPerform :: SecretKey d -> PublicKey d -> ScrubbedBytes

Performs DH.

dhPubToBytes :: PublicKey d -> ScrubbedBytes

Exports a PublicKey.

dhBytesToPub :: ScrubbedBytes -> Maybe (PublicKey d)

Imports a PublicKey.

dhSecToBytes :: SecretKey d -> ScrubbedBytes

Exports a SecretKey.

dhBytesToPair :: ScrubbedBytes -> Maybe (KeyPair d)

Imports a SecretKey.

dhPubEq :: PublicKey d -> PublicKey d -> Bool

Tests PublicKeys for equality.
