OpenSSH 7.6 已发布，OpenSSH 是一个 100％ 完整的 SSH 2.0 协议实现，包括 sftp 客户端和服务器支持。

ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC.
ssh(1)/sshd(8): remove support for the arcfour, blowfish and CAST ciphers.
Refuse RSA keys <1024 bits in length and improve reporting for keys that do not meet this requirement.
