Puttygen id_rsa.pub

To convert the PPK files, you need the package putty-tools.

On a Debian or Ubuntu you can install this package simply with:

apt-get install putty-tools

The actual conversion is done using the command puttygen.

Creation of the public key:

puttygen key.ppk -o id_rsa.pub -O public-openssh

Creation of the private key:

puttygen key.ppk -o id_rsa -O private-openssh

Now you copy both files id_rsa and id_rsa.pub in the corresponding user home into the subdirectory will add the key.

ssh-add -l will list all available identities.
