If you’re using a .ppk<\/code> (PuTTY Private Key) on macOS, you’ll often need to convert it to the OpenSSH .pem<\/code> format before using it with SSH, Git, Ansible, or cloud servers.<\/p>\n\n\n\n

Prerequisites<\/h2>\n\n\n\n

Install PuTTY<\/strong> (which includes puttygen<\/code>) using Homebrew:<\/p>\n\n\n\n

brew install putty<\/pre>\n\n\n\n
Verify the installation:<\/p>\n\n\n\n
puttygen --version<\/pre>\n\n\n\n
Convert PPK to PEM<\/h2>\n\n\n\n
Run the following command:<\/p>\n\n\n\n
puttygen private-key.ppk -O private-openssh -o private-key.pem<\/pre>\n\n\n\n
Example:<\/p>\n\n\n\n
puttygen myserver.ppk -O private-openssh -o myserver.pem<\/pre>\n\n\n\n
If the .ppk<\/code> file is protected with a passphrase, puttygen<\/code> will prompt you to enter it during the conversion.<\/p>\n\n\n\n
Set Correct Permissions<\/h2>\n\n\n\n
Secure the PEM file before using it:<\/p>\n\n\n\n
chmod 400 myserver.pem<\/pre>\n\n\n\n
or<\/p>\n\n\n\n
chmod 600 myserver.pem<\/pre>\n\n\n\n
Connect Using SSH<\/h2>\n\n\n\n
Use the converted key to connect to your server:<\/p>\n\n\n\n
ssh -i myserver.pem ubuntu@your-server-ip<\/pre>\n\n\n\n
Example:<\/p>\n\n\n\n
ssh -i myserver.pem ubuntu@192.168.1.100<\/pre>\n\n\n\n
Verify the PEM Key<\/h2>\n\n\n\n
Check that the converted key is valid:<\/p>\n\n\n\n
ssh-keygen -lf myserver.pem<\/pre>\n\n\n\n
Troubleshooting<\/h2>\n\n\n\n
puttygen: command not found<\/code><\/h3>\n\n\n\n
Install PuTTY:<\/p>\n\n\n\n
brew install putty<\/pre>\n\n\n\n
If Homebrew is not installed:<\/p>\n\n\n\n
\/bin\/bash -c \"$(curl -fsSL https:\/\/raw.githubusercontent.com\/Homebrew\/install\/HEAD\/install.sh)\"\nbrew install putty<\/pre>\n\n\n\n
Permission Denied<\/h3>\n\n\n\n
Ensure the key permissions are restricted:<\/p>\n\n\n\n
chmod 400 myserver.pem<\/pre>\n\n\n\n
Invalid PPK File<\/h3>\n\n\n\n
Verify that the file is a valid PuTTY private key and has not been corrupted.<\/p>\n\n\n\n
Summary<\/h2>\n\n\n\n
Task<\/th>Command<\/th><\/tr>
Install PuTTY<\/td>brew install putty<\/code><\/td><\/tr>
Convert PPK to PEM<\/td>puttygen myserver.ppk -O private-openssh -o myserver.pem<\/code><\/td><\/tr>

Conclusion<\/h2>\n\n\n\n
Converting a .ppk<\/code> file to a .pem<\/code> file on macOS is straightforward using puttygen<\/code>. Once converted, the PEM key can be used with OpenSSH, Git, Ansible, AWS EC2, DigitalOcean, and other Linux servers without requiring PuTTY.<\/p>\n","protected":false},"excerpt":{"rendered":"
