Motivation: HTTP is a plaintext protocol which means that someone may be able to eavesdrop the data. To prevent this, HTTPS should be used whenever possible. However, maintaining using https:// in all URLs may be difficult. The nohttp tool can help here. The tool scans all the files in a repository and reports where http:// is used. Modifications: - Added nohttp (via checkstyle) into the build process. - Suppressed findings for the websites that don't support HTTPS or that are not reachable Result: - Prevent using HTTP in the future. - Encourage users to use HTTPS when they follow the links they found in the code.
