Crypto.PubKey.Ed448

Ed448 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 8032.

Smart constructors

signature :: ByteArrayAccess ba => ba -> CryptoFailable Signature

Try to build a signature from a bytearray

publicKey :: ByteArrayAccess ba => ba -> CryptoFailable PublicKey

Try to build a public key from a bytearray

secretKey :: ByteArrayAccess ba => ba -> CryptoFailable SecretKey

Try to build a secret key from a bytearray

Methods

toPublic :: SecretKey -> PublicKey

Create a public key from a secret key

sign :: ByteArrayAccess ba => SecretKey -> PublicKey -> ba -> Signature

Sign a message using the key pair The public key parameter is ignored and its public key is generated from the secret key parameter to prevent Double Public Key Signing Function Oracle Attack.

unsafeSign :: ByteArrayAccess ba => SecretKey -> PublicKey -> ba -> Signature

Sign a message using the key pair. This is old sign, which is vulnerable to private key compromise if the given public key does not correspond to the secret key. This function is provided for performance critical applications. To use it safely, applications must verify or derive the public key.

verify :: ByteArrayAccess ba => PublicKey -> ba -> Signature -> Bool

Verify a message

generateSecretKey :: MonadRandom m => m SecretKey

Generate a secret key
