I simply changed few things to make this filter supporting logstash 5.x

based on -->https://github.com/elastic/logstash/blob/5.x/docs/static/breaking-changes.asciidoc#ruby-filter-and-custom-plugin-developers

Hi guys, I want to report a problem that I'm facing now using the cipher filter.

As far as i use the filter with a basic configuration such as input from file, cipher filter for encrypting a field and an output file, works pretty well.

When I switch to a pipeline configuration more complex (3 inputs from rabbit, complex logic filter, output elasticsearch and file) it returns an exception

Exception catch on cipher filter {:event=>2017-03-02T10:46:47.576Z %{host} %{message}, :error=>#<NoMethodError: undefined method iv=' for nil:NilClass>}`

The fact that the filter works fine using another pipeline makes me confused about what possible error I'm facing here....

Any suggestions?

Ok the issue is definitely when I use rabbitmq as input for logstash...

sorry, I fixed the issue. It was missing a configuration for rabbitmq input
