To extract an OpenSSH compatible public key from it, you can just run: ssh-keygen -f private.pem -y > private.pub If you just want to share the private key, the OpenSSL key generated by your example command is stored in private.pem, and it should already be in PEM format compatible with (recent) OpenSSH. This means that you need to store the X.509 certificate, in addition to the private key, if you wish use the same key for both OpenSSL and OpenSSH.
The certificate contains information that is not present anywhere else and each certificate is unique and can not be recreated at will. Also, these certificates are not X.509, so they are incompatible with OpenSSL. OpenSSH does have support for certificates as well, but it is likely that you are not using this support. This certificate is not something OpenSSH traditionally uses for anything - and it definitely is not the same thing as a public key only. However, the OpenSSL command you show generates a self-signed certificate. Private keys are normally already stored in a PEM format suitable for both. create a shortcut to pageant in your Startup menu and give it the key file name as a commandline parameter so this is loaded automatically for you.Ssh-keygen can be used to convert public keys from SSH formats in to PEM formats suitable for OpenSSL.
In Puttygen, in the 'Conversions' menu choose 'Import' and load id_rsa.ppk.Convert this file into the right format to use with Putty:.if you already have a default id_rsa that you use with git, you can set up a C:\Users\Aquib\.ssh\config file that tells SSH where to find the key and tell it which servers it should use it for. if you don't want to use this for all servers, or e.g.ssh -i id_rsa.ppk make a folder C:\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 to specify the file on the command line e.g.Use this key with command-line SSH (it's in the correct format).However this is an OpenSSH-format private key and needs to be converted to Putty's own format to use in Putty. You've used ssh-keygen to create a private key file called id_rsa.ppk.
#OPENSSH SSH KEYGEN WINDOWS 10#
Has anyone tried this method on windows 10 to generate keys?
Your public key has been saved in C:\publickey\id_. Your identification has been saved in C:\publickey\id_rsa.ppk. 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))īelow is the command which i used to generate key pairs on windows 10 C:\Users\xxx>ssh-keygen -t rsa -b 2048 -C public/private rsa key pair.Įnter file in which to save the key (C:\Users\xxx/.ssh/id_rsa): C:\publickey\id_rsa.ppkĮnter passphrase (empty for no passphrase): It exports private and public key in a location. I've tried this but with unsuccessful attempt.Īs per the article click here ask us to use below command and it completes successfully. 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 been using Puttygen to generate SSH Key pair for Azure Linux VM.
