Use “ssh-keygen” command.
Use “PUTTYGEN.EXE” software, which is typically located in the c:\Program Files\putty\ directory and apply the “Generate” button.
To use CLI (Command Line Interface) access the unit with a PuTTY client. Access is protected by a key. The key can be in Linux format and it begins:
-----BEGIN DSA PRIVATE KEY----- .....
or in PuTTY format which begins:
PuTTY-User-Key-File-2: ssh-dss .....
To convert the Linux format to PuTTY do the following:
In c:\Program Files\putty\ directory run PUTTYGEN.EXE
Click on “Load” and choose the Linux private key.
In the next window type your password into the “Key passphrase” and “Confirm passphrase” fields. After that click “Save private key”. Choose location and save the key.
In PuTTY menu fill in the address, e.g.
email@example.com and the name of the link, e.g. RAy 17
Go to “Connection / SSH / Auth” in the left column and locate the key C:\downloads\ray.ppk
Go back to “Session” and Save the configuration.
To connect select the name of the connection and click Open. PuTTY asks for password created during key conversion.
