cipher.final([output_encoding]) Returns any remaining enciphered contents. If output_encoding parameter is one of 'binary', 'base64' or 'hex', a string is returned. If an output_encoding is not provided, a Buffer is returned. Once the cipher.final() method has been called, the Cipher object can no longer be used to encrypt data. Attempts to call cipher.final() more than once will result in an error being thrown.

ecdh.setPrivateKey(private_key[, encoding]) Sets the EC Diffie-Hellman private key. The encoding can be 'binary', 'hex' or 'base64'. If encoding is provided, private_key is expected to be a string; otherwise private_key is expected to be a Buffer. If private_key is not valid for the curve specified when the ECDH object was created, an error is thrown. Upon setting the private key, the associated public point (key) is also generated and set in the ECDH object.

hash.digest([encoding]) Calculates the digest of all of the data passed to be hashed (using the hash.update() method). The encoding can be 'hex', 'binary' or 'base64'. If encoding is provided a string will be returned; otherwise a Buffer is returned. The Hash object can not be used again after hash.digest() method has been called. Multiple calls will cause an error to be thrown.

Stability: 2 - Stable A stream is an abstract interface implemented by various objects in Node.js. For example a request to an HTTP server is a stream, as is process.stdout. Streams are readable, writable, or both. All streams are instances of EventEmitter. You can load the Stream base classes by doing require('stream'). There are base classes provided for Readable streams, Writable streams, Duplex streams, and Transform streams. This document is split up into 3 sections: The first section e

socket.write(data[, encoding][, callback]) Sends data on the socket. The second parameter specifies the encoding in the case of a string--it defaults to UTF8 encoding. Returns true if the entire data was flushed successfully to the kernel buffer. Returns false if all or part of the data was queued in user memory. 'drain' will be emitted when the buffer is again free. The optional callback parameter will be executed when the data is finally written out - this may not be immediately.

server.setTimeout(msecs, callback) msecs <Number> callback <Function> Sets the timeout value for sockets, and emits a 'timeout' event on the Server object, passing the socket as an argument, if a timeout occurs. If there is a 'timeout' event listener on the Server object, then it will be called with the timed-out socket as an argument. By default, the Server's timeout value is 2 minutes, and sockets are destroyed automatically if they time out. However, if you assign a callb

agent.maxSockets By default set to Infinity. Determines how many concurrent sockets the agent can have open per origin. Origin is either a 'host:port' or 'host:port:localAddress' combination.

fs.lstatSync(path) Synchronous lstat(2). Returns an instance of fs.Stats.

Class Method: Buffer.isBuffer(obj) obj <Object> Return: <Boolean> Returns 'true' if obj is a Buffer.

socket.ref() Opposite of unref, calling ref on a previously unrefd socket will not let the program exit if it's the only socket left (the default behavior). If the socket is refd calling ref again will have no effect. Returns socket.
