## Overview

This small Go plugin adds a configurable fingerprint processor to Elastic Beats. Beats loads the plugin and configures the processor; for each event, the processor reads configured fields, hashes their values, encodes the digest, and writes it to the target field. Hash algorithms and output encodings are selected from the supported options. The graph reflects the excerpts and README; no additional runtime wiring is inferred.

Main entry points: [`fingerprint.go`](https://github.com/andrewkroh/beats-processor-fingerprint/blob/master/fingerprint.go) (Fingerprint processor), [`main.go`](https://github.com/andrewkroh/beats-processor-fingerprint/blob/master/main.go) (Plugin registration), [`config.go`](https://github.com/andrewkroh/beats-processor-fingerprint/blob/master/config.go) (Hash and encoding options)
