Since the private key is never transmitted over the connection, the public-key authentication method is considered to be more secure than the password authentication method. In contrast with the "password" authentication method where the password is transmitted between the client and the server during the authentication process, the private key contents are not transmitted between the client and the server. Typically the private-key file on the client's machine is protected by a "passphrase", so even if the private-key file is stolen, an attacker must still know the passphrase in order to use it. Public-key authentication is only successful when the client proves that it possesses the "secret" private key linked to the public-key file that the server is configured to use. While the private and public keys within a key pair are related, a private key cannot be derived by someone who only possesses the corresponding public key. The public and private keys are generated with a key generation utility. Public-key authentication employs a linked pair of computer-generated keys - one public and one private - and a procedure that proves the user's identity without exposing the secret key to theft or hijacking.īefore using public-key authentication, the public/private key pair files must be created, with a copy of the public-key file being uploaded to a specific location on the server. Public-key authentication is a proven, well-established method for authenticating computing devices which is more secure than password authentication. Overview of public-key authentication for Secure Shell The tip below provides a basic overview of public-key authentication, explains how to generate and upload keys to the Secure Shell server, and shows how to configure SecureCRT and SecureFX clients. this is my first blog.Index Using Public-Key Authentication in Secure Shell Applications Please leave you comments.how did you find it? and remember. I guess you know what is coming next.I need not to explain how to copy the sessions folder to the same location on any other windows box where you want to setup secureCRT/SecureFX and yes.you do not want to redo all the session creations.:) The same is c:\documents and settings\ in WindowsXP and prior versions. Just as a word of caution., with Windows 7, Microsoft has changed the users home directory to C:\Users\. You just need to copy the sessionsfolder and save it to some location. \AppData\Roaming\Van Dyke Technologies\SecureCRT\Config\sessions. SecureCRT saves the user sessions information under windows user home directory. If you are using SecureFx/SecureCRT on Windows. Last thing you need to do is import this key to any other windows system where putty is running. Just export this key and save it to some location or external drive if you plan to move to some different windows box. You can find the sessions saved in putty at HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions location. Putty actually does not have any config or ini file, it writes all the user created sessions in windows registry. I did some research "well by that I meant googling also.:)" and here is how a little information can help you. And all three had at least 30 saved sessions having IP/user/pwd information, reconfiguring those sessions would be a daunting tasks. I was using Putty, SecureCRT and SecureFX to log on to client side boxes and to work upon. During all this exercise I realized that by this I can only back up the data, what about the work I am doing.my configurations and installations.? What the heck.I need to spend lot of time to redo all that.crap. To begin with, here are couple of tips that could save you some time.Īctually, I had once this problem where I have to take backup and move my work data to a new laptop and as we normally do, I also put my data on some external drive and copied it to the new box. This is my first stint with blogging and I thought why not just start with sharing some useful information/tricks that can save you some time.
