better exception logging has been merged: https://github.com/logstash-plugins/logstash-filter-fingerprint/pull/1

The documentation here sucks.. key is listed as optional, however, it's not truly optional at all.
"When used with IPV4_NETWORK method fill in the subnet prefix length Not required for MURMUR3 or UUID methods With other methods fill in the HMAC key."
This needs to be clarified, and highlighted better.

After reading the docs, this looks to be a problem where I don't specify a key in the config. It would be nice if the documentation was clearer on what the key is and when it needs to be specified.
Also a simple error throw when user omits a key and it's required instead of the hard-to-decipher stacktrace.
Fixed

Using this filter causes an exception to be thrown for SHA* and MD5 (MURMUR3 worked)
fingerprint { source => "message" method => "SHA256" }
The error is:
