A simple hashing library designed to create easy (for humans) to remember hash values
Babble hash creates a hash value that is optimized for humans to remember the generated value. The hash value consists of common English dictionary words and a short string of digits.
BabbleHash bh = new BabbleHash()
bh.hash("[email protected]") // output is "ForestCloud03264"
Babble by default tries to create an inoffensive hash value by using a curated dictionary of words. If you want to use a different dictionary of words, you can load a custom dictionary from a yaml file. Bear in mind that a small dictionary could lead to hash collisions.
The size of the hash set for the default babble implementation is dictionary_size ^ 2 * 2 ^ 16.
// Construct the dictionary from a java.util.Collection
Dictionary collectionDict = new Dictionary(["fox", "kilo", "alpha"])
BabbleHash collectionHash = new BabbleHash(library: collectionLib)
// Read library from a yaml file
Dictionary yamlDict = new Dictionary(new File("path/to/file", "yamlKey")
BabbleHash yamlHash = new BabbleHash(library: yamlLib)
Babble by default will use a 128 bit murmur3 hash to digest the supplied string to hash. If desired, this algorithm can be replaced with a different one, for example, if a cryptographic hash is desired. Guava's Hashing contains a variety of hash functions that can be passed to the BabbleHash class's constructor.
// From guava
import com.google.common.hash.HashFunction
import com.google.common.hash.Hashing
BabbleHash cryptoHash = new BabbleHash(hashFunction: Hashing.sha256())
