Crypto.PubKey.Curve448

Description

Curve448 support

Internally uses Decaf point compression to omit the cofactor and implementation by Mike Hamburg. Externally API and data types are compatible with the encoding specified in RFC 7748.

Smart constructors

dhSecret :: ByteArrayAccess b => b -> CryptoFailable DhSecret Source #

Create a DhSecret from a bytearray object

publicKey :: ByteArrayAccess bs => bs -> CryptoFailable PublicKey Source #

Try to build a public key from a bytearray

secretKey :: ByteArrayAccess bs => bs -> CryptoFailable SecretKey Source #

Try to build a secret key from a bytearray

Methods

dh :: PublicKey -> SecretKey -> DhSecret Source #

Compute the Diffie Hellman secret from a public key and a secret key.

This implementation may return an all-zero value as it does not check for the condition.

toPublic :: SecretKey -> PublicKey Source #

Create a public key from a secret key

generateSecretKey :: MonadRandom m => m SecretKey Source #

Generate a secret key.
