Setup PuTTYgen for ssh key 



        start puttygen.exe

                    The little program looks like this:

puttygen_pic1
Now at first check the "Parameters" at the bottom of the window

We need at "Type of key to generate" > SSH-2 RSA enabled
and in the field for "Number of bits in a generated key" we type "1024"
   
            that looks like this:    

puttygen_parameters_settings


## 1. = generate keys

Click the "Generate" Button - follow the instructions and move your mouse wild over the blank field in the middle to generate random stuff.

puttygen_gen_key


When its done you looking at such a thing:

puttygen_generated_keys

Its time to enter a passphrase and confirm it - its a must otherwise it wont work ( and keep that passphrase in mind! )

Click on "Save private key" when you are done.
See:
puttygen_seekeysnbutton

This will generate a .ppk file which PuTTY needs later to connect with the phone.
Give it a file name and save it where you can find it later again. ( In my example i named it putty_private_key.ppk )



## 2. = copy the file for phone

        Ok thats the tricky part ;)

Go to the previously ( In part 2 ) copied "dropbear_easy_setup" folder and open the "key_for_authorization.txt" file with your favourite texteditor.

Now back to the "PuTTY Key Generator" window

Select all of the " Public key for pasting into OpenSSH authorized_keys file:" output and copy it into the opened "key_for_authorization.txt" file.
It starts with "ssh-rsa" and ends with something like " ....=rsa-key-20...."
puttygen_ssh-rsa_copy

        The textfile should now look like this:

textfilelook


Save the file and copy the whole "dropbear_easy_setup" folder back to its old place on the sdcard of the phone. Overwrite the old/empty file there.

Then disconnect the phone from the pc, go back to the sshControl app and touch the big OK button.

When your Phone  is ready make PuTTY run on your Windows pc.
