Protecting external communication with HTTPS

In this section, we will learn how to prevent eavesdropping on external communication, for example from the internet, via the public APIs exposed by the edge server. We will use HTTPS to encrypt communication. To use HTTPS, we need to do the following:

  • Create a certificate: We will create our own self-signed certificate, sufficient for development purposes.
  • Configure the edge server: It has to be configured to accept only HTTPS-based external traffic using the certificate.

The self-signed certificate is created with the following command:

keytool -genkeypair -alias localhost -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore edge.p12 -validity 3650
