-## How to generate RSA private key and digital certificate
-
-1. Install Openssl
-
-Please visit https://github.com/openssl/openssl to get pkg and install.
-
-2. Generate RSA private key
-
-```sh
-$ mkdir testdata
-$ openssl genrsa -out ./testdata/server.key 2048
-```
-
-3. Generate digital certificate
-
-```sh
-$ openssl req -new -x509 -key ./testdata/server.key -out ./testdata/server.pem -days 365
