Examples with SigAlgo net.i2p.crypto.SigAlgo used on opensource projects

Example 1 with SigAlgo

use of net.i2p.crypto.SigAlgo in project i2p.i2p by i2p.

the class I2PSocketManagerFull method connect.

/**
 * Create a new connected socket. Blocks until the socket is created,
 * unless the connectDelay option (i2p.streaming.connectDelay) is
 * set and greater than zero. If so this will return immediately,
 * and the client may quickly write initial data to the socket and
 * this data will be bundled in the SYN packet.

 * @param peer Destination to connect to
 * @param options I2P socket options to be used for connecting, may be null
 *
 * @return I2PSocket if successful
 * @throws NoRouteToHostException if the peer is not found or not reachable
 * @throws I2PException if there is some other I2P-related problem
