Instances
data TLSCertificateRejectReason Source
Certificate and Chain rejection reason
Context object
ctxConnection :: TLSCtx a -> aSource
return the connection object associated with this context
Creating a context
Arguments
| :: (MonadIO m, CryptoRandomGen g) | |
| => TLSParams | parameters to use for this context |
| -> g | random number generator associated with the context |
| -> Handle | handle to use |
| -> m (TLSCtx Handle) |
Create a new Client context with a configuration, a RNG, and a Handle.
It reconfigures the handle's BufferMode to NoBuffering.
server :: (MonadIO m, CryptoRandomGen g) => TLSParams -> g -> Handle -> m (TLSCtx Handle)Source
Create a new Server context with a configuration, a RNG, and a Handle.
It reconfigures the handle's BufferMode to NoBuffering.
Initialisation and Termination of context
bye :: MonadIO m => TLSCtx c -> m ()Source
notify the context that this side wants to close connection. this is important that it is called before closing the handle, otherwise the session might not be resumable (for version < TLS1.2).
this doesn't actually close the handle
handshake :: MonadIO m => TLSCtx c -> m ()Source
Handshake for a new TLS connection This is to be called at the beginning of a connection, and during renegotiation
High level API
sendData :: MonadIO m => TLSCtx c -> ByteString -> m ()Source
sendData sends a bunch of data. It will automatically chunk data to acceptable packet size
recvData :: MonadIO m => TLSCtx c -> m ByteStringSource
recvData get data out of Data packet, and automatically renegotiate if a Handshake ClientHello is received
recvData' :: MonadIO m => TLSCtx c -> m ByteStringSource
Crypto Key
Compressions & Predefined compressions
class CompressionC a whereSource
