Convert SSL PEM to PPK

If you have created an SSH-RSA certificate in the OpenStack portal, it will be created in ".PEM" format. However, for use in Putty, you need the ".PPK" format. One way to convert it is by using the tool puttygen .

Using the PuTTYgen UI

• Open PuTTYgen and select SSH-2 RSA as the key type to generate.

• Then click on "Load" on the right side and set the file type to "AllFiles *.*".

• Browse and open your .pem file, which is usually located in the Download directory. When you open it, you will receive the following message.

PuTTY automatically detects everything it needs.

• Optionally enter a password (Key passphrase), then click "Save private key". The .PPK file will be saved in the same location where the .PEM file was.

Important

We recommend using a "Key passphrase" to protect the use of the "Private Key" with a password.

How to access my created Linux VM from Putty

If you have not yet installed Putty, download the application from the following official Putty page and install it.

Prerequisites The following prerequisites are necessary to access your VM:

• Port 22 (Ingress) must be open (see Create Security Groups Rule)
• The VM must have a Floating IP (Public IP) (see Associate Floating IP)
• You need your created Private Key in .PPK format (see Create ssh Key Pair)

Open the program putty.exe and enter the username and the Floating IP address of the instance in the "Host Name (or IP address)" field.

Then click on Auth, enter the path to your Public Key (.PPK), and click "Open" to establish the connection.

Confirm any security prompts with "Yes". If you set a password when converting the key, you will be prompted to enter the password.

Note

If you want to permanently make your Private Key known in Putty, install the application pageant.exe (see Putty Help)
