HTTP Body Hash Generator
This CLI (Command Line Interface) tool sends HTTP GET requests and print MD5 hash values of the response's body.
Usage
You need Go to build the app.
After build tha app, you can use it in command line. The app get URL list from command line arguments.
Example:
$ ./myapp google.com facebook.com yahoo.com yandex.com twitter.com reddit.com/r/funny reddit.com/r/notfunny baroquemusiclibrary.com
yandex.com 38edd673423f7dc9fbe919d7ea7b49cb

In order to reduce waiting time, the app sends parallel requests. The default count of parallel workers is 10, but you can use -parallel flag to change that value.
Example:
./myapp -parallel 3 google.com facebook.com yahoo.com yandex.com twitter.com reddit.com/r/funny reddit.com/r/notfunny baroquemusiclibrary.com

Development
If you want to use a different method to get URL list, another hashing algorithm, or printing to file etc, the only thing you need to do is implementing an adapter for it and use it in main.go. You don't need to change buisiness logic for these type of changes.
Unit Tests
There are some unit tests in the project. If you need to add new test cases, you can easily add them into testCases array in related test file.
