Safer Access without Passwords
How do you make sure that your passwords are safe? You can make them longer, complicate them by adding odd characters, making sure to use different passwords for each user account that you have. Or, you can simply skip them all together.
The secure shell, ssh, is a key tool in any Linux user's toolbox. As soon as you have more than one machine to interact with, ssh is the obvious choice.
When logging into a remote machine through ssh, you are usually prompted with the remote user's password. An alternative to this is to use an asymmetric key pair.
An asymmetric key pair consists of a private and public key. These are generated from an algorithm - either RSA or DSA. RSA has been around for a long time and is widely supported, even by old legacy implementations. DSA is safer, but requires v2 of the ssh protocol. This is not much of an issue in an open source world - keeping the ssh daemon implementation up to date is not a problem, but rather a requirement. Thus, DSA is the recommended choice, unless you have any specific reason to pick RSA.
The generated keys are larger than a common user password. RSA keys are at least 768 bits, default 2048 bits. DSA keys are 1024, as the standard specifies this.
To generate a DSA key, use the following command:Read More...
Interesting info... I have tried setting this up in the past and got stuck on things that didn't work on one of the machines in the Command Line. So, I got tired of messing with it. If there were an easy GUI way of doing all this. I think average users could do it and take advantage of the extra Security in this method. And like some in the comments section of his Blog say. These files are readable by anyone who gains accecess to your machine. Locally or Remotely... So, if your Hacked, Your Hacked!:O
