clkhash: Cryptographic Linkage Key Hashing

clkhash is a python implementation of cryptographic linkage key hashing as described by Rainer Schnell, Tobias Bachteler, and Jörg Reiher in A Novel Error-Tolerant Anonymous Linking Code [Schnell2011].

Clkhash is Apache 2.0 licensed, supports Python versions 2.7+, 3.5+, and runs on Windows, OSX and Linux.

Install with pip:

pip install clkhash

Hint

If you are interested in comparing CLK encodings (i.e carrying out record linkage) you might want to check out anonlink and anonlink-entity-service - our Python library and REST service for computing similarity scores, and matching between sets of cryptographic linkage keys.
