Constructor Summary

EncryptedSocket(Identifier identifier, P2PSocket<Identifier> socket, Logger logger, ErrorHandler<Identifier> handler, java.util.Map<java.lang.String,java.lang.Object> options, javax.crypto.Cipher encryptCipher, javax.crypto.Cipher decryptCipher, int writeBufferSize)

Method Summary

long	read(java.nio.ByteBuffer output) Reads a sequence of bytes from this channel into a subsequence of the given buffer.
void	receiveSelectResult(P2PSocket<Identifier> socket, boolean canRead, boolean canWrite) Called when a socket is available for read/write
long	write(java.nio.ByteBuffer srcs) Writes a sequence of bytes to this channel from a subsequence of the given buffers.
protected long	writeHelper(java.nio.ByteBuffer srcs) Only to be called holding the encryptedWriteBuffer, probably should only be called from this.write()
