PUTTY SSH KEY AUTHENTICATION PASSWORD
PUTTY SSH KEY AUTHENTICATION WINDOWS

Use SFTP or SCP to copy the public key file (for example, ~/.ssh/id_rsa.pub) to your account on the remote system (for example, for example, using command-line SCP:.pub extension added) and stored in the same location (for example, ~/.ssh/id_rsa.pub or ~/.ssh/my_ssh_key.pub). The corresponding public key will be generated using the same filename (but with a. ssh directory off your home directory (for example, ~/.ssh/id_rsa or ~/.ssh/my_ssh_key). Your private key will be generated using the default filename (for example, id_rsa) or the filename you specified (for example, my_ssh_key), and stored on your computer in a. If you don't password-protect your private key, anyone with access to your computer conceivably can SSH (without being prompted for a password) to your account on any remote system that has the corresponding public key. If you press Enter or Return without entering a password, your private key will be generated without password-protection.

PUTTY SSH KEY AUTHENTICATION PASSWORD

Password: Enter a password that contains at least five characters, and then press Enter or Return.

Consequently, to authenticate with a private key that has a different filename, or one that is not stored in the default location, you must explicitly invoke it either on the SSH command line or in an SSH client configuration file ( ~/.ssh/config) see below for instructions. However, many remote hosts are configured to accept private keys with the default filename and path ( ~/.ssh/id_rsa for RSA keys) by default.

Filename: To accept the default filename (and location) for your key pair, press Enter or Return without entering a filename.ДЄlternatively, you can enter a filename (for example, my_ssh_key) at the prompt, and then press Enter or Return.

You will be prompted to supply a filename (for saving the key pair) and a password (for protecting your private key):.

To generate RSA keys, on the command line, enter:

Log into the computer you'll use to access the remote host, and then use command-line SSH to generate a key pair using the RSA algorithm.

If you have questions about how two-factor authentication may impact your workflows, contact the UITS Research Applications and Deep Learning team.

SSH public key authentication remains an option for researchers who submit the 'SSH public key authentication to HPS systems' agreement (log into HPC everywhere using your IU username and passphrase), in which you agree to set a passphrase on your private key when you generate your key pair. Two-factor authentication using Two-Step Login (Duo) is required for access to the login nodes on IU research supercomputers, and for SCP and SFTP file transfers to those systems. Therefore, you must either be able to log into the remote system with an established account username and password/passphrase, or have an administrator on the remote system add the public key to the ~/.ssh/authorized_keys file in your account.

You need to be able to transfer your public key to the remote system.

This document includes instructions for generating a key pair with command-line SSH on a Linux or macOS computer, and with PuTTY on a Windows computer.

The computer you use to connect to the remote server must have a version of SSH installed.

If the remote system is using a different version of SSH (for example, Tectia SSH), the process outlined below may not be correct. The information in this document assumes the remote system uses OpenSSH.

The remote system must have a version of SSH installed.Conceivably, you can share the public key with anyone without compromising the private key you store it on the remote system in a. You keep the private key a secret and store it on the computer you use to connect to the remote system. SSH public key authentication relies on asymmetric cryptographic algorithms that generate a pair of separate keys (a key pair), one 'private' and the other 'public'. Using SSH public key authentication to connect to a remote system is a robust, more secure alternative to logging in with an account password or passphrase.
