Another issue you might encounter is "Unable to load config info from /usr/local/ssl/openssl.cnf", which is due to OpenSSL relying on a Linux default arborescence.
To troubleshoot these issues, try executing simplified commands.
Here are some basic commands to get you started:
- Generate a private key with the command: openssl genrsa 2048 > website-file.key
- Generate a CSR with the command: openssl req -new -key website-file.key > website-file.csr
- Alternatively, you can use the command: openssl req -new -key website-file.key -config "C:\Program Files\OpenSSL-Win64\openssl.cnf" -out website-file.csr
If you're still having trouble, make sure to download the openssl.cnf file and place it in the correct location, such as C:\Program Files\OpenSSL-Win64\openssl.cnf.
Important Information
The OpenSSL path on Windows can be a bit tricky to find.
You can check the OpenSSL path by looking in the Environment Variables section of the System Properties.
The OpenSSL path is usually located in the PATH variable, which is a list of directories that Windows searches for executables.
The default OpenSSL path on Windows is typically C:\OpenSSL-Win32\bin.
Make sure to add the OpenSSL path to your system's PATH variable for it to be recognized by your system.
Unpacking and Verification
Unpack the OpenSSL zip file into your desired location, like we did in the example where we used the D:\OpenSSL folder.
The zip file contains three main folders: bin, include, and lib, which will be extracted during the unpacking process.
To verify the unpacking process, ensure that the three folders are present in your specified location.
Make sure to check the contents of each folder to confirm that they match the expected files.
The bin folder contains the executable files, the include folder contains the header files, and the lib folder contains the library files.
