hhash

hhash is a consistent, human-readable hashing engine

why

author desired something like the docker container name generator but with consistent hashing and rich custom pattern

installation

$ go get github.com/choey/hhash
$ go get github.com/choey/hhash/cmd/hhash

features

• supports custom pattern
• generates random human-readable string
• generates human-readable hash
• reports collision rate for the given datasets

futures

• add dataset for person names
• scrub datasets to be less offensive

examples

• random string (which is just the hash of a random UUID)

$ hhash
cedarn_kappa

• custom pattern (upper case adverb followed by uppercase adjective)

$ hhash -p '[%n-%n]'
[devon-freeware]

• value hash

$ hhash -s 'hello, world' -v
2019/02/07 23:36:09 using pattern: %j_%n
2019/02/07 23:36:09 elapsed time 373.439µs

$ hhash -s 'hello, world' -v
2019/02/07 23:36:33 using pattern: %j_%n
2019/02/07 23:36:33 elapsed time 331.244µs

(verbose mode calculates collision rate and thus is slightly slower than non-verbose mode)
