Public key cryptography uses a public key to encrypt a piece of data, and then the recipient uses the private key to decrypt the data. The public and private keys are known as a key pair. Public key cryptography enables you to securely access your instances using a private key instead of a password. This article provides detailed background and steps to create and manage an SSH RSA public-private key file pair for SSH client connections. If you want quick commands, see How to create an SSH public-private key pair for Linux VMs in Azure. Ssh-keygen -f idrsa -e -m pem This will convert your public key to an OpenSSL compatible format. Your private key is already in PEM format and can be used as is (as Michael Hampton stated). Double check if AWS isn't asking for a (X.509) certificate in PEM format, which would be a different thing than your SSH keys. Openssl genrsa -out private.pem 1024 To generate public (e,n) key from the private key using openssl you can use the following command: openssl rsa -in private.pem -out public.pem -pubout To dissect the contents of the private.pem private RSA key generated by the openssl command above run the following (output truncated to labels here).

One of the most common forms of cryptography today is public-key cryptography helps to communicate two system by encrypting information using the public key and information can be decrypted using private key. These keys are using mainly on login to server securely and also transferring data securely.

We can generate these private public keys by various ways.

1) By using openssl.

with password encryption

Generate public key:

2) By using ssh keygen

3) using putty-gen for windows.

Download puttyGen from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html and run it.

You can select one of the key types, SSH-1, SSH-2, and SSH-2 DSA.
SSH-2 is probably better than others but you have to make sure if your system supports SSH-2, if your system ( server) doesnt support it then you better off with SSH-1.

Level of encryption can be set from “Number of bits in a generated key” . Security level can be enhance by using 2048 but again make sure where you are using it and thus follow the recommendation for this value. I prefer 2048 but even with 1024 is much more secure. Win xp key generator online.

Click on generate to create keys. Move your mouse over the empty space to help puttygen to genereate random variables.

Once the key is generated you will see following window.

If you want to login without password ( in case of ssh login) you can put your passphase empty. click on Save Public key and Save private key to save your keys.

When you save private key it will be saved in ppk format which you can use putty to login to your system.

We can get private key for openSSH by clicking on Conversions->Export OpenSSH key

If you want to use ssh to login with these generated key / pair then
copy public key ( mykey.pub) to .ssh/authorized_key.
