Download and install latest version of OpenSSL for windows from http://www.slproweb.com/products/Win32OpenSSL.html. \\ **Note:** OpenSSL requires [[https://www.microsoft.com/en-us/download/|Visual C++ 2008 Redistributables]] which can be downloaded from the same website. 2. Open command prompt, navigate to **C:\OpenSSL-Win32\bin>**, and run the following commands. Set OPENSSL_CONF=c:\openssl-win32\bin\openssl.cfg openssl pkcs12 -in filename.pfx -nocerts -out key.pem openssl rsa -in key.pem -out myserver.key 3. The private key will be saved as ‘myserver.key’. \\ 4. Carefully protect the private key. Be sure to backup the private key, as there is no means to recover it, should it be lost. \\ Credits:[[https://docs.druva.com/Knowledge_Base/inSync/How_To/Using_Microsoft_IIS_to_generate_CSR_and_Private_Key|Druva]]
