甚至比重新打开puttygen更快，我经常做的是:

复制公钥文件。 在副本中，将单词“ssh-rsa”放在开头。 删除开始/结束注释行和所有其他换行符。 保存。结果是一个适用于openssh的一行键。

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

打开PuttyGen 点击加载 加载您的私钥 转到转换->导出OpenSSH并导出您的私钥 将您的私钥复制到~/。Ssh /id_dsa(或id_rsa)。 使用ssh-keygen创建公钥的RFC 4716版本 Ssh-keygen -e -f ~/。Ssh /id_dsa > ~/.ssh/id_dsa_com.pub 将RFC 4716版本的公钥转换为OpenSSH格式: Ssh-keygen -i -f ~/.ssh/id_dsa_com. shPub > ~/.ssh/id_dsa.pub

看这个和这个了解更多信息。

道克→PPK OpenSSH和PuttyGen RSA &。

私钥:

docker run --rm -v $(pwd):/app zinuzoid/puttygen private.ppk -O private-openssh -o my-openssh-key

公共密钥:

docker run --rm -v $(pwd):/app zinuzoid/puttygen private.ppk -L -o my-openssh-key.pub

参见https://hub.docker.com/r/zinuzoid/puttygen

如果你只有一个用户的putty格式的公钥，你可以把它转换成标准的openssh格式，如下所示:

ssh-keygen -i -f keyfile.pub > newkeyfile.pub

I keep forgetting this so I'm gonna write it here. Non-geeks, just keep walking. The most common way to make a key on Windows is using Putty/Puttygen. Puttygen provides a neat utility to convert a linux private key to Putty format. However, what isn't addressed is that when you save the public key using puttygen it won't work on a linux server. Windows puts some data in different areas and adds line breaks. The Solution: When you get to the public key screen in creating your key pair in puttygen, copy the public key and paste it into a text file with the extension .pub. You will save you sysadmin hours of frustration reading posts like this. HOWEVER, sysadmins, you invariably get the wonky key file that throws no error message in the auth log except, no key found, trying password; even though everyone else's keys are working fine, and you've sent this key back to the user 15 times. ssh-keygen -i -f keyfile.pub > newkeyfile.pub Should convert an existing puttygen public key to OpenSSH format.

新版本的PuTTYgen(我的是0.64)能够在.ssh/authorized_keys文件中显示要粘贴到linux系统中的OpenSSH公钥，如下图所示:

我最近从Linux的Putty转移到Linux的Remmina时遇到了这个问题。所以我在我的。Putty目录中有很多PPK文件，因为我已经使用它8年了。为此，我使用了一个简单的命令为bash shell做所有文件:

cd ~/.putty
for X in *.ppk; do puttygen $X -L > ~/.ssh/$(echo $X | sed 's,./,,' | sed 's/.ppk//g').pub; puttygen $X -O private-openssh -o ~/.ssh/$(echo $X | sed 's,./,,' | sed 's/.ppk//g').pvk; done;

非常快速和要点，得到的工作完成了所有的文件，腻子。如果它发现一个带有密码的密钥，它将停止并首先询问该密钥的密码，然后继续。
