我正在端口443上运行一个简单的node.jshttps服务器。运行SSLScan时，以下是接受的密码：

 Accepted  SSLv3  256 bits  AES256-SHA
 Accepted  SSLv3  128 bits  AES128-SHA
 Accepted  SSLv3  168 bits  DES-CBC3-SHA
 Accepted  SSLv3  128 bits  RC4-SHA
 Accepted  TLSv1  256 bits  AES256-SHA
 Accepted  TLSv1  128 bits  AES128-SHA
 Accepted  TLSv1  168 bits  DES-CBC3-SHA
 Accepted  TLSv1  128 bits  RC4-SHA

我不明白的是，为什么实际支持的密码列表要短那么多？

更令人困惑的是，当我在node中获得支持的密码列表tls.getCiphers()时，我会发现一个很长的列表：
