Windows 7 - How to generate CSR when IIS is not installed

Question

Answer 1

If you need to generate CSRs from code and you are using some of .NET languages, use BouncyCastle or our SecureBlackbox. They both support certificate requests in PKCS#10 format. For C++ you can probably use OpenSSL.

Answer 2

Digicert has an easy to use tool for managing certificates on Windows: https://www.digicert.com/util/

If had the capability to generate certificate requests. It will also convert certificates between different formats

Answer 3

For a more recent version of openssl...
https://www.openssl.org/community/binaries.html links to
https://wiki.openssl.org/index.php/Binaries which links to
http://slproweb.com/products/Win32OpenSSL.html which has links for win64 and win32 openssl.

Otherwise, you should be able to install openssl v0.98h on windows with this:
http://gnuwin32.sourceforge.net/packages/openssl.htm

Run the openssl at the command prompt (Start->Run->"cmd.exe"):
openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key
or you can use this online tool to generate the openssl command:
https://www.digicert.com/easy-csr/openssl.htm

When you run the openssl req command on your computer, it will generate a CSR (with public key embedded) and private key.
