First release v1.4 of hashlookup-lib

Hashlookup is a library to import hashes records into a hashlookup server.

The library cleans up the format in the entry, do normalization such as upper-case of hex hashes, verify meta-field definition and ensure consistency in the key/value store.

A hashlookup server is a Redis-compatible datastore to allow fast-lookup of forensic values.
