```
static final String PROP_FAST_RECEIVE
```
    For router->client payloads. If false, the router will send the MessageStatus, the client must respond with a ReceiveMessageBegin, the router will send the MessagePayload, and the client respond with a ReceiveMessageEnd. If true, the router will send the MessagePayload immediately, and will not send a MessageStatus. The client will not send ReceiveMessageBegin or ReceiveMessageEnd. Default false, but the implementation in this package sets to true.

  - createDestination
```
Destination createDestination(OutputStream destKeyStream)
                       throws I2PException,
                              IOException
```
    Create a new destination with the default certificate creation properties and store it, along with the private encryption and signing keys at the specified location. Caller must close stream.
    Parameters:
    destKeyStream - stream to write destination and keys to
    Returns:
    new destination
    Throws:
    I2PException - on I2P protocol error
    IOException - on IO error
  - createDestination
```
Destination createDestination(OutputStream destKeyStream,
                              Certificate cert)
                       throws I2PException,
                              IOException
```
    Create a new destination with the given certificate and store it, along with the private encryption and signing keys at the specified location. Caller must close stream.
    Parameters:
    destKeyStream - stream to write destination and keys to
    cert - certificate to tie to the destination
    Returns:
    newly created destination
    Throws:
    I2PException - on I2P protocol error
    IOException - on IO error
  - createDestination
```
Destination createDestination(OutputStream destKeyStream,
                              SigType type)
                       throws I2PException,
                              IOException
```
    Create a destination with the given signature type. It will have a null certificate for DSA 1024/160 and KeyCertificate otherwise. This is not bound to the I2PClient, you must supply the data back again in createSession(). Caller must close stream.
    Parameters:
    destKeyStream - location to write out the destination, PrivateKey, and SigningPrivateKey, format is specified in PrivateKeyFile
    type - the signature type for the destination
    Returns:
    new destination
    Throws:
    I2PException - on I2P protocol error
    IOException - on IO error
  - createSession
```
I2PSession createSession(InputStream destKeyStream,
                         Properties options)
                  throws I2PSessionException
```
    Create a new client session for the Destination stored at the destKeyStream using the specified options to both connect to the router, to instruct the router how to handle the new session, and to configure the end to end encryption. As of 0.9.19, defaults in options are honored.
    Parameters:
    destKeyStream - location from which to read the Destination, PrivateKey, and SigningPrivateKey from, format is specified in PrivateKeyFile
    options - set of options to configure the router with, if null will use System properties
    Returns:
    new session allowing a Destination to receive all of its messages and send messages to any other Destination.
    Throws:
    I2PSessionException - if there is a problem creating the session
