+### Generate Private and Public RSA Key
+
+OpenSSL Project is dedicated to providing a simple installation of OpenSSL for Microsoft Windows. [Download](https://slproweb.com/products/Win32OpenSSL.html)
+
+Generate an RSA private key, of size 2048, and output it to a file named `private_key.pem` in to `./keys`
+
+```shell
+openssl genrsa -out private_key.pem 2048
+```
+
+Extract the public key from `private_key.pem` from `./keys`, and output it to a file named `public_key.pem` in to `./keys`
+
+```shell
+openssl rsa -in private_key.pem -pubout -out public_key.pem
