Crypto.Curve25519.Exceptions
Description
An implementation of the core methods of the elliptic curve Curve25519 suite. These functions are largely wrappers over the curve25519-donna library from Google. Note that those functions that utilize a CryptoRandomGen instance may throw a GenError exception if the generator fails for any reason.
Synopsis
- data PrivateKey
- data PublicKey
- importPublic :: ByteString -> Maybe PublicKey
- exportPublic :: PublicKey -> ByteString
- generatePrivate :: CryptoRandomGen g => g -> (PrivateKey, g)
- generatePublic :: PrivateKey -> PublicKey
- generateKeyPair :: CryptoRandomGen g => g -> (PrivateKey, PublicKey, g)
- makeShared :: PrivateKey -> PublicKey -> ByteString
Documentation
data PrivateKey Source #
The type of a Curve25519 private key.
Instances
| Show PrivateKey Source # | |
Defined in Crypto.Curve25519.Pure Methods showsPrec :: Int -> PrivateKey -> ShowS # show :: PrivateKey -> String # showList :: [PrivateKey] -> ShowS # | |
The type of a Curve25519 public key.
importPublic :: ByteString -> Maybe PublicKey Source #
Import a public key from a ByteString. The ByteString must be exactly 32 bytes long for this to work.
exportPublic :: PublicKey -> ByteString Source #
Export a public key to a ByteString.
generatePrivate :: CryptoRandomGen g => g -> (PrivateKey, g) Source #
Randomly generate a Curve25519 private key.
generatePublic :: PrivateKey -> PublicKey Source #
Randomly generate a Curve25519 public key.
generateKeyPair :: CryptoRandomGen g => g -> (PrivateKey, PublicKey, g) Source #
Randomly generate a key pair.
makeShared :: PrivateKey -> PublicKey -> ByteString Source #
Generate a shared secret from a private key and a public key.
