OpenSSH 免费的SSH通讯软件
OpenSSH 是 SSH （Secure SHell） 协议的免费开源实现。SSH协议族可以用来进行远程控制， 或在计算机之间传送文件。而实现此功能的传统方式，如telnet(终端仿真协议)、 rcp ftp、 rlogin、rsh都是极为不安全的，并且会使用明文传送密码。OpenSSH提供了服务端后台程序和客户端工具，用来加密远程控件和文件传输过程中的数据，并由此来代替原来的类似服务。
OpenSSH 7.5 发布了，该版本主要是一个 Bug 修复版本。
但本次更细使得特权分离的使用是强制性的，并且删除对旧的、不支持的 OpenSSL 版本的支持。
部分更新内容：
In the next major release (expected June-August), removing remaining support for the SSH v.1 protocol (currently client-only and compile-time disabled).
In the same release, removing support for Blowfish and RC4 ciphers and the RIPE-MD160 HMAC. (These are currently run-time disabled).
In the same release, removing the remaining CBC ciphers from being offered by default in the client (These have not been offered in sshd by default for several years).
Refusing all RSA keys smaller than 1024 bits (the current minimum is 768 bits)
