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.

data SecretKey #

A Curve448 Secret key

Instances

Eq SecretKey # 
Show SecretKey # 
NFData SecretKey # 

Methods

rnf :: SecretKey -> () #

ByteArrayAccess SecretKey # 

Methods

length :: SecretKey -> Int

withByteArray :: SecretKey -> (Ptr p -> IO a) -> IO a

data PublicKey #

A Curve448 public key

Instances

Eq PublicKey # 
Show PublicKey # 
NFData PublicKey # 

Methods

rnf :: PublicKey -> () #

ByteArrayAccess PublicKey # 

Methods

length :: PublicKey -> Int

withByteArray :: PublicKey -> (Ptr p -> IO a) -> IO a

data DhSecret #

A Curve448 Diffie Hellman secret related to a public key and a secret key.

Instances

Eq DhSecret # 
Show DhSecret # 
NFData DhSecret # 

Methods

rnf :: DhSecret -> () #

ByteArrayAccess DhSecret # 

Methods

length :: DhSecret -> Int

withByteArray :: DhSecret -> (Ptr p -> IO a) -> IO a

Smart constructors

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

Create a DhSecret from a bytearray object

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

Try to build a public key from a bytearray

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

Try to build a secret key from a bytearray

methods

dh :: PublicKey -> SecretKey -> DhSecret #

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 #

Create a public key from a secret key

generateSecretKey :: MonadRandom m => m SecretKey #

Generate a secret key.
