如何将使用PuTTYgen(Windows)生成的SSH密钥对转换为ssh-agent和Keychain(Linux)使用的密钥对 [英] How to convert SSH keypairs generated using PuTTYgen (Windows) into key-pairs used by ssh-agent and Keychain (Linux)

问题描述

我已使用PuTTYgen生成了密钥对，并已使用Pageant登录，因此，在系统启动时，只需输入一次密码.

I've generated key pairs using PuTTYgen and been logging in using Pageant, so that I have to enter my pass-phrase only once when my system boots.

如何在Linux中实现这一目标?我听说过keychain，但是我听说它使用了不同的密钥对格式-我不想更改Windows密钥，如果我可以在Windows和Linux中以相同的方式无缝连接，那就太好了.

How do I achieve this in Linux? I've heard of keychain but I hear that it uses a different key pair format - I don't want to change my Windows keys and it would be nice if I could seamlessly connect in the same manner in both Windows and Linux.

推荐答案

puttygen支持将您的私钥导出为与OpenSSH兼容的格式.然后，您可以使用OpenSSH工具重新创建公钥.

puttygen supports exporting your private key to an OpenSSH compatible format. You can then use OpenSSH tools to recreate the public key.

1. 打开PuttyGen
2. 点击加载
3. 加载您的私钥
4. 转到Conversions->Export OpenSSH并导出您的私钥
5. 将您的私钥复制到~/.ssh/id_dsa(或id_rsa).

6. 使用ssh-keygen

1. Open PuttyGen
2. Click Load
3. Load your private key
4. Go to Conversions->Export OpenSSH and export your private key
5. Copy your private key to ~/.ssh/id_dsa (or id_rsa).

6. Create the RFC 4716 version of the public key using ssh-keygen

ssh-keygen -e -f ~/.ssh/id_dsa > ~/.ssh/id_dsa_com.pub

将公用密钥的RFC 4716版本转换为OpenSSH格式:

Convert the RFC 4716 version of the public key to the OpenSSH format:

ssh-keygen -i -f ~/.ssh/id_dsa_com.pub > ~/.ssh/id_dsa.pub
