Problem Statement

While working on mercurial(Version Control System), we need to generate different public/private keys for windows & Linux, which leads to have multiple keys for single user.

Solution

If we want to access mercurial through Linux with your same key as Windows, then instead of generating a new rsa key pair ,we can reuse same public/private key pair to access mercurial from linux.
Hence same repository you can access via windows or linux without creating separate public/private key pair for both.

STEPS :

Pre-requisite: There must a key pair existing in SSH2 format to access mercurial`

Open the PuTTY Key Generator
On the menu bar, click "File" -> "Load private key"
Select your .ppk file
On the menu bar, click "Conversions" -> "Export OpenSSH key"
Save the file as (without an extension) e.g. mercurial_rsa `

You are all done. Same private key on windows can be reused(with above steps) with Linux.
