How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
OR
ssh-keygen

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

Generating a Secure Shell (SSH) Public/Private Key Pair; Generating a Secure Shell (SSH) Public/Private Key Pair. Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms. Set the Type of key to generate option to SSH-2 RSA. When you set up SSH, you create a key pair that contains a private key (saved to your local computer) and a public key (uploaded to Bitbucket). Bitbucket uses the key pair to authenticate anything the associated account can access. This two-way mechanism prevents man-in-the-middle attacks. This first key pair is your default SSH identity. Oct 05, 2007  Generating Keys. Generating public keys for authentication is the basic and most often used feature of ssh-keygen. Ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a.

  • $HOME/.ssh/id_rsa – Your private RSA key
  • $HOME/.ssh/id_rsa.pub – Your public RSA key

  1. To extract public key from the private key file into separate public key file you use your openssl rsa -in private.pem -pubout -out public.pem command. When you produce a public key this way, it is extracted from the private key file, not calculated.
  2. Issue the following command at a shell prompt (by default, Mac OS Terminal uses a bash shell): ssh-keygen -t rsa -b 2048. This will create a RSA public/private key pair in the.ssh directory below your account’s home directory. For example: Location: /.ssh (where is the home directory) Private key file name: idrsa.
  3. Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub email address. $ ssh-keygen -t rsa -b 4096 -C 'youremail@example.com' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair.
  4. When connecting to the instance via SSH, a trusted connection to the machine is being established using the key pair. If there is a discrepancy between the keys or any of them is missing, authentication fails and a connection cannot be established. Important: For security reasons you must generate a 2048-bit or 4096-bit RSA key. Older 1024-bit.

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id userName@server2.nixcraft.net.in
Finally, you can login to remote server as follows:
ssh userName@server2.nixcraft.net.in
scp file.txt userName@server2.nixcraft.net.in:~/data2/
