So I am in the process of releasing an application to iOS but I don’t have a Mac. One of the things that I need to do for releasing development versions of my application I need to create a Certificate Signing Request (CSR). Follow the steps below in order to be able to do it.
1) Download OpenSSL if you don’t already have it. There is an installer available
2) Open a command prompt.
3) Set the location of the configuration file using set OPENSSL_CONF=c:\OpenSSL-Win32\bin\openssl.cfg otherwise you’ll get the warning. WARNING: can’t open config file: /usr/local/ssl/openssl.cnf
4) cd \OpenSSL-Win32\bin
5) openssl req -nodes -newkey rsa:2048 -keyout private_key.key -out cer_sign_request.csr
6) Fill out the answers to the questions. Most are self explanatory.
7) You should now have a file called cer_sign_request.csr in \OpenSSL-Win32\bin
