Generating Putty SSH Key Pair

1. Run the Puttygen (i.e. Putty Key Generator).

2. Click the Generate button.
3. Move the mouse cursor on the blank area provided by the generator.
4. Update the Key comment field if desired.
5. Provide an identical passphrase to the following fields if desired:
   • Key passphrase
6. • Confirm passphrase

6. Click Save private key button.

7. Click Save public key if desired.

The content of public key file is the one to be copied on the server with the following format:

ssh-rsa <CONTINUOUS_PUBLIC_KEY> <KEY_COMMENT>

And the file normally have the following format:

---- BEGIN SSH2 PUBLIC KEY ----
Comment: <KEY_COMMENT>
<DELIMITED_PUBLIC_KEY>
---- END SSH2 PUBLIC KEY ----

You are reading it right, in the file, the public key (i.e. DELIMITED_PUBLIC_KEY) is delimited by a carriage return. Thus, you need to remove it to have the CONTINUOUS_PUBLIC_KEY.
