How to Convert .pem to .ppk with Putty

PEM format is a type of file storage format for storing cryptographic keys and certificates. Unlike most cryptographic file storage standards that store content binary, the PEM format uses base64 for encoding, which makes file transfer and reading much easier. On the other hand, the PPK file contains the private key generated by the PuTTYgen tool and used by PuTTY. PuTTY is a terminal emulator program that can act as a client for raw SSH, Telnet, rlogin and TCP computing protocols. In this article, we try to learn you how to Convert .pem to .ppk with Putty on Windows and Linux. You can visit the packages available in Eldernode to purchase the Linux VPS server and Windows VPS server.

Users can use the PuTTY tool to securely connect and transfer data from localhost to remote systems. You should also know that to use PuTTY, private keys must be present in the main application format.

Suppose that as EC2, a core part of the cloud computing operating system creates the PEM file format. The user must first convert the file to an .ppk file format before connecting to the Linux Instance.

It should be noted that if someone intends to use the SSH PuTTY client to connect, they must first convert the .pem file to .ppk using PuTTYgen. Once it has done so, it can use the PuTTY program to join local and remote hosts.

Introduction to .pem file format

PEM stands for Privacy-Enhanced Mail. This file extension is a form used primarily for the private transmission of data, email, and encryption keys. PEM format is also a very safe and secure way to store and transfer data. It is interesting to know that The .pem file format encodes it with the binary-to-text encoding scheme – base64 so that it represents binary data in ASCII string.

Introduction to .ppk file format

PPK files are PuTTY Private Key files. The .ppk file extension tells you which program can open the file. It should be noted that different applications may use the same file extension for different types of data. As a result, a .ppk opener may not be able to open all types of .ppk files. The .ppk file format is used to enable secure communication with a remote inventory that has the corresponding public key.

$sudo apt-get install putty-tools

Now you can easily convert your .pem file to an .ppk file using the following command in the sample shell:

$ sudo puttygen pemKey.pem -o ppkKey.ppk -O private
