public class EclcSocket
extends Socket

对等口令长连接协议：拥有相同口令的A和B可以建立长连接的socket连接。 协议目的：防止恶意程序经过公网开放的ip和端口对区块链进行长连接攻击，也就意味着拥有口令的节点才能真正和其他节点进行建立网络连接。提升区块链网络安全能力/防止ddos攻击/提升网络传输效率。 协议步骤： 1. A用户用口令“123”对明文“ABC”进行加密，并得到密文“@A”发送给B用户 2. B用户收到A寄来的密文，同时进行解密得出明文“ABC”，此时B用户用自己id口令“123”对明文“BCD”进行加密得出密文“@B” B用户同时将“ABC”和“@B”返回给A用户 3. A用户收到B的响应对比返回的明文是“ABC”，同时也要对B发过来的密文进行解密得出明文“BCD”，最后将明文“BCD”发送给B用户。 4. B用户收到A用户发送过来的明文是“BCD”和自己在上步骤使用的明文是一致的，此时协议完成，A和B可以建立socket长连接。
