ssh - 如何向没有密码生成的 OpenSSH 私钥添加密码？

Question

我使用 PuTTYgen 生成了 OpenSSH 私钥(并以 OpenSSH 格式导出)。

如何在现有 key 上设置密码(我知道如何生成带有密码的新 key )？

Answer 1

尝试以下命令:

ssh-keygen -p -f keyfile

来自 ssh-keygen 手册页

 -p      Requests changing the passphrase of a private key file instead of
         creating a new private key.  The program will prompt for the file
         containing the private key, for the old passphrase, and twice for
         the new passphrase.

 -f filename
         Specifies the filename of the key file.

示例:

ssh-keygen -p -f ~/.ssh/id_rsa
