subdomain-enumerator's Issues

Assignment

Hey there. I refactored the code with some improvements to the interface and conformed it to the latest version of ReconLib. It works just like before, but some major improvements are now up to you.

1. Add CLI option for API key of VirusTotal

Even though we know that this is not the ideal use of the tool, a user might still find it convenient to pass an API key value through the CLI, like in --virustotal-api-key SOME-API-KEY-VALUE. The current implementation uses environment variables (which is the preferred way), but try to do something about the CLI as well.

2. Use one thread for each service

Right now we have the tool spawn a new thread for each domain being fetched, which is less than ideal specially when all we want is to fetch the subdomains for a single domain. It's querying each service sequentially, which takes time. Try to make it so each service is queried in parallel for a given domain, but set the number of threads in a way that doesn'1 overload the APIs.

You'll probably need some sort of exception handling because some APIs may return a 403 when exceeding usage quotas.
