+Generating SSH keys 生成 SSH 密钥
+===========
+
+*跳过本指南。直接下载我们的原生[ windows 应用程序](https://windows.github.com/)*
+
+SSH 密钥通常用来验证计算机，而无需提供密码。本文说明了如何生成 SSH  密钥 并把它添加到你的 Github 账号。
+
+*提示：我们建议您定期审查您的 [SSH 密钥列表](https://help.github.com/articles/keeping-your-ssh-keys-and-application-access-tokens-safe)和撤销那些没有被使用的。*
+
+##Step 1: Check for SSH keys 检查 SSH 密钥
+
+首先，我们需要检查您的计算机中现有的 SSH 密钥。打开你的 Git Bash 和输入：
+
+	$ ls -al ~/.ssh
+	# Lists the files in your .ssh directory, if they exist
+
+下列为已经存在的文本：
+
+* id_dsa.pub
+* id_ecdsa.pub
+* id_ed25519.pub
+* id_rsa.pub
+
+##Step 2: Generate a new SSH key 生成新的 SSH 密钥
+
+生成一个新的SSH密钥，复制并粘贴下面的文本，确保替代你的电邮地址。默认设置是首选的，所以当你提示“Enter a file in which to save the key”，按回车继续。
+
+	$ ssh-keygen -t rsa -C "your_email@example.com"
+	# Creates a new ssh key, using the provided email as a label
+	Generating public/private rsa key pair.
+	Enter file in which to save the key (/c/Users/you/.ssh/id_rsa): [Press enter]
+
+接下来，输入密码
+ 
+*提示：我们强烈推荐使用一个很好的，安全的密码。更多信息，见 [SSH 密钥的口令工作](https://help.github.com/articles/working-with-ssh-key-passphrases)。*
+
+	Enter passphrase (empty for no passphrase): [Type a passphrase]
+	Enter same passphrase again: [Type passphrase again]
+
+显示如下：
+
+	Your identification has been saved in /c/Users/you/.ssh/id_rsa.
+	Your public key has been saved in /c/Users/you/.ssh/id_rsa.pub.
+	The key fingerprint is:
+	01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@example.com
+
+添加你的新的密钥到  ssh-agent（ssh 代理）
+
+	# start the ssh-agent in the background
+	$ ssh-agent -s
+	Agent pid 59566
+	$ ssh-add ~/.ssh/id_rsa
+
+##Step 3: Add your SSH key to GitHub 添加 SSH 密钥到 Github
+
+运行下面命令，拷贝 密钥 到 剪贴板，记住 密钥 名称可能是  id_dsa.pub, id_ecdsa.pub 或 id_ed25519.pub.
+
+	$ clip < ~/.ssh/id_rsa.pub
+	# Copies the contents of the id_rsa.pub file to your clipboard
+
+另外，使用您最喜爱的文本编辑器，你可以手动打开公共密钥文件和复制文件的内容。
+
+现在，你有钥匙的拷贝，是时候添加到GitHub：
+
+1. 点击右上角设置按钮![setting](https://help.github.com/assets/images/help/settings/userbar-account-settings.png);
+2. 点击 **SSH keys** ![SSH KEY](https://help.github.com/assets/images/help/settings/settings-sidebar-ssh-keys.png)
+3. 点击 **Add SSH key** ![add](https://help.github.com/assets/images/help/settings/ssh-add-ssh-key.png)
+4. 填入 密钥的描述
+5. 填入 密钥。![填入 密钥](https://help.github.com/assets/images/help/settings/ssh-key-paste.png)
+6. 点击 **Add key** ![add key](https://help.github.com/assets/images/help/settings/ssh-add-key.png)
+7. 确认密码
+
+##Step 4: Test everything out 测试
+
+打开 Git Bash 输入:
+
+	$ ssh -T git@github.com
+	# Attempts to ssh to github
+
+看到如下警告
+
+	The authenticity of host 'github.com (207.97.227.239)' can't be established.
+	RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
+	Are you sure you want to continue connecting (yes/no)?
+
+输入 “yes”
+
+	Hi username! You've successfully authenticated, but GitHub does not
+	provide shell access.
+
+如果 username 是你的用户名，说明你已经成功了。
+
+如果收到”access denied（拒绝访问）“的信息。 [阅读这些问题诊断说明](https://help.github.com/articles/error-permission-denied-publickey)。
