I have created an EC2 instance on AWS. I want to connect to the instance using PuTTY, but it requires PPK file. I have PEM file which I want to covert into PPK using PuTTYgen.
How do I use PuTTYgen on Ubuntu to convert PEM file to PPK?
With *nix version of PuTTYgen:
puttygen mykey.pem -o mykey.ppk
See PuTTYgen man page.
On Ubuntu, you can install the PuTTY package with sudo apt install putty-tools.
For Windows users: Note that Windows version of PuTTYgen does not support key conversions from command-line.
You can use WinSCP with the /keygen command-line switch instead to convert the key, like:
winscp.com /keygen mykey.pem /output=mykey.ppk
For compatibility with PuTTYgen, WinSCP also supports its syntax:
winscp.com /keygen mykey.pem -o mykey.ppk
