Documentation
type SecretKey = SizedByteArray CRYPTO_BOX_SECRETKEYBYTES ScrubbedBytes Source #
Secret key that can be used for Box.
toSecretKey :: ScrubbedBytes -> Maybe SecretKey Source #
Convert bytes to a secret key.
type PublicKey = SizedByteArray CRYPTO_BOX_PUBLICKEYBYTES ByteString Source #
Public key that can be used for Box.
toPublicKey :: ByteString -> Maybe PublicKey Source #
keypair :: IO (PublicKey, SecretKey) Source #
Generate a new SecretKey together with its PublicKey.
Note: this function is not thread-safe (since the underlying
C function is not thread-safe both in Sodium and in NaCl)!
Either make sure there are no concurrent calls or see
Crypto.Init in
crypto-sodium
to learn how to make this function thread-safe.
type Nonce a = SizedByteArray CRYPTO_BOX_NONCEBYTES a Source #
Nonce that can be used for Box.
This type is parametrised by the actual data type that contains
bytes. This can be, for example, a ByteString.
toNonce :: ByteArrayAccess ba => ba -> Maybe (Nonce ba) Source #
Make a Nonce from an arbitrary byte array.
This function returns Just if and only if the byte array has
the right length to be used as a nonce with a Box.
Arguments
| :: (ByteArrayAccess nonce, ByteArrayAccess pt, ByteArray ct) | |
| => PublicKey | Receiver’s public key |
| -> SecretKey | Sender’s secret key |
| -> Nonce nonce | Nonce |
| -> pt | Plaintext message |
| -> IO ct |
Encrypt a message.
