OpenSSH implements a SFTP client and server. A file format for public keys is specified in the publickeyfile draft. The command ssh-keygen(1) can be used to convert an OpenSSH public key to this file format. The Diffie-Hellman Group Exchange allows clients to request more secure groups for the Diffie-Hellman key exchange. ATTENTION In order to allow using one time passwords (OTPs) and any other text input, Keyboard-interactive is enabled in OpenSSH. This MAY allow for password authentication to work. It is therefore very important to check your PAM configuration so that PAM disallow password authentication for OpenSSH. OpenSSH 6.3+ (default) File: /etc/ssh/sshd. I do not want to start ssh-agent and ssh-add as described here to manage my ssh keys for password less login. How do I install keychain software to manage my keys running on a Debian or Ubuntu based cloud server? OpenSSH offers RSA and DSA authentication to remote systems without supplying a password. Keychain is a manager for ssh-agent.

Openssl aes-256-cbc -in somefile.enc -out somefile.unenc -d. This then prompts for the pass key for decryption. I searched the openssl documents and the interwebs to try and find the answer if I simply wanted to give the password to the command without trying to echo the password to the file. To enable SSH password authentication, you must SSH in as root to edit this file: /etc/ssh/sshdconfig. Then, change the line. PasswordAuthentication no. PasswordAuthentication yes. After making that change, restart the SSH service by running the following command as root: sudo service ssh restart Enable Logging In as root.

OpenSSH 是一款用于远程登录的连接工具，它使用 SSH 协议。OpenSSH is a connectivity tool for remote login that uses the SSH protocol.它会加密客户端与服务器之间的所有流量，从而遏止窃听、连接劫持和其他攻击。It encrypts all traffic between client and server to eliminate eavesdropping, connection hijacking, and other attacks.

OpenSSH 可用于将 Window 10 客户端连接到 Windows Server 2019。OpenSSH can be used to connect Window 10 clients to Windows Server 2019.OpenSSH 客户端可安装到 Windows 10 版本 1809 及更高版本上，而 OpenSSH 服务器可安装在 Windows Server 2019 及更高版本上。OpenSSH Client is available to install on Windows 10 build 1809 and later, while OpenSSH Server is available to install on Windows Server 2019 and later.

使用 Windows 设置来安装 OpenSSHInstall OpenSSH using Windows Settings

这两个 OpenSSH 组件都可使用 Windows 设置进行安装。Both OpenSSH components can be installed using Windows Settings.OpenSSH 服务器安装在 Windows Server 上，OpenSSH 客户端安装在 Windows 10 设备上。OpenSSH Server is installed on Windows Server and OpenSSH Client is installed on Windows 10 devices.

若要安装 OpenSSH 组件：To install the OpenSSH components:

1. 打开“设置”，选择“应用”>“应用和功能”，然后选择“可选功能” 。Open Settings, select Apps > Apps & Features, then select Optional Features.

2. 扫描列表，查看是否已安装 OpenSSH。Scan the list to see if the OpenSSH is already installed.如果未安装，请在页面顶部选择“添加功能”，然后：If not, at the top of the page, select Add a feature, then:

   • 在 Windows 10 上，查找“OpenSSH 客户端”，再单击“安装” On Windows 10, find OpenSSH Client, then click Install
   • 在 Windows Server 2019 上，查找“OpenSSH 服务器”，再单击“安装” On Windows Server 2019, find OpenSSH Server, then click Install

设置完成后，回到“应用”>“应用和功能”和“可选功能”，你应会看到已列出 OpenSSH 。Once setup completes, return to Apps > Apps & Features and Optional Features and you should see OpenSSH listed.

备注

安装 OpenSSH 服务器将创建并启用一个名为 OpenSSH-Server-In-TCP 的防火墙规则。Installing OpenSSH Server will create and enable a firewall rule named OpenSSH-Server-In-TCP.这允许端口 22 上的入站 SSH 流量。This allows inbound SSH traffic on port 22.如果未启用此规则且未打开此端口，那么连接将被拒绝或重置。If this rule is not enabled and this port is not open, connections will be refused or reset.
