I've been using Puttygen to generate SSH Key pair for Azure Linux VM. recently i found openssh is available on Windows 10 and i can use "ssh-keygen" command on Windows 10 CMD and generate Private and Public Key.
I've tried this but with unsuccessful attempt.
As per the article click here ask us to use below command and it completes successfully. It exports private and public key in a location. But when i load the private key in putty and connect to my server it throws error
Unable to use key file "C:\publickey\id_rsa.ppk" (OpenSSH SSH-2 private key (old PEM format))
login as:
Below is the command which i used to generate key pairs on windows 10
C:\Users\xxx>ssh-keygen -t rsa -b 2048 -C "azureuser@vm"
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\xxx/.ssh/id_rsa): C:\publickey\id_rsa.ppk
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\publickey\id_rsa.ppk.
Your public key has been saved in C:\publickey\id_rsa.ppk.pub.
The key fingerprint is:
Has anyone tried this method on windows 10 to generate keys?
You've used ssh-keygen to create a private key file called id_rsa.ppk. However this is an OpenSSH-format private key and needs to be converted to Putty's own format to use in Putty.
Your options are:
ssh -i id_rsa.ppk azureuser@vmC:\Users\Aquib\.ssh and move it there as C:\Users\Aquib\.ssh\id_rsa (no extension): ssh will now load this file by default to use for all servers that you try to connect toC:\Users\Aquib\.ssh\config file that tells SSH where to find the key and tell it which servers it should use it for.For Linux (for example Ubuntu) you can install the command line puttygen like this:
# sudo apt install putty-tools
... and generate from your local ssh-key id_rsa to putty version id_rsa.ppk like this:
# puttygen id_rsa -O private -o id_rsa.ppk
