I am pretty new on the Oracle Cloud Infrastructure technology, so maybe I am talking about something you already know. But anyway I prefer to share this case: it can help if you encounter the same problem as me. Let’s take the risk to have too much information rather than nothing! 😉
Actually I don’t work directly on a Linux system. So I need to convert my private key if I want to make it usable via my connection tools.
First step is to transform it to RSA format. I can do it using OpenSSL:
# openssl rsa -in ssh-key-2020-11-24.key -out ssh-key-2020-11-24.rsa
Second and last step is to convert it to ppk format. I can do it using PuTTYgen.
I load the private key:
I filter on all files types:
I select my RSA key and I click on Open:
I click on Ok on the following message:
and then on Save private key:
So I save the key with a ppk format:
Hope this can help you!
