I was given the private key for an SFTP server on a remote network. The key was generate using puttygen.exe or similar program on a Windows system. I needed to using public key authentication to access the server. This is what I did to generate a public key to authenticate.<\/p>\n
On a Windows system, I ran puttygen.exe and imported the private key. You can either do this as a parameter to the puttygen.exe program or import the key once you have started puttygen.exe:<\/p>\n
puttygen somebodys.ppk <\/p><\/blockquote>\n
Once the key is imported, you can change the key comment from imported-openssh-key to something more meaningful. And enter and confirm your choice of passphrase. <\/p>\n
Then save the public key by clicking the button.<\/p>\n
Copy the newly generated public key to the openssh sftp client machine.<\/p>\n
Put the file in file in the ~\/.ssh directory and secure it (chmod 400 ~.ssh\/somebodys.pub).<\/p>\n
Then you just have to pass it to your sftp command.<\/p>\n
$ sftp -i ~\/.ssh\/somebody.pub myusername@their.host.name<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
