I've some questions about the "fingerprint" module of Logstash.
After some tests, I've noticed few things:
- "key" parameter mandatory, but the documentation says not
- As per the "key" is mandatory, the hashed field can't be reversed
So, here are the questions:
- Is it possible to use the fingerprint plugin without key?
- Is there a way to reverse a hashed field?
Thank you all for your feedbacks!
