Auto SSH login

I have tried using puttygen.exe to generate private and public key pair for SSH auto login via putty. The public key will need to be uploaded to the directory /home/user/.ssh/ and renamed as authorized_keys. There is a need to use vi to edit the public key file to add ssh-rsa in the beginning and remove carriage return and new line. Afterwards, one has to config putty to authenticate a login user by private key. The steps are quite confused but fortunately they are all clearly spelt out in the URL http://www.codelathe.com/blog/index.php/2009/02/20/ssh-without-password-using-putty/.

The use of private key for auto login also works for sftp. The sftp client that I use is WinSCP.
