【问题描述】：

我生成了一对 rsa 密钥，然后我把公钥放在 github 上，但是当我尝试ssh git@github.com时，它仍然需要一个密码，就像这样：

$ ssh git@github.com
git@github.com\'s password:

我确定我已经通过ssh-keygen -t rsa -C \"xxx\" 创建了正确的私钥和公钥

uchin@DESKTOP-UCHIN MINGW64 ~/.ssh
$ ls -lah
total 74K
drwxr-xr-x 1 uchin 197121    0 Sep 30 19:46 ./
drwxr-xr-x 1 uchin 197121    0 Sep 30 19:25 ../
-rw-r--r-- 1 uchin 197121  576 Sep 30 19:45 id_rsa.pub
-rw-r--r-- 1 uchin 197121 2.6K Sep 30 19:45 id_rsa.rsa
-rw-r--r-- 1 uchin 197121  484 Sep 30 19:46 known_hosts

我也上传了我的公钥，github public key

我已经尝试了很多次，但它从来没有奏效。

这是ssh -Tv git@github.com的一些信息

我想知道如何让它工作，谢谢

【解决方案1】：

ssh 输出并不表明GitHub 服务器接受您的密钥.所以请检查您是否正确上传了等效的公钥。

您可以通过访问网址验证公钥是否上传成功：https://github.com/<your_github_username>.keys

例如，假设您的用户名是uchin，那么您可以在https://github.com/uchin.keys 看到您的所有公钥

如果密钥不匹配，则重新上传公钥。如果不是，请重新运行ssh -vvv git@github.com，并在此处分享输出。
