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 3.5+, and runs on Windows, OSX and Linux. Clkhash is part of the Anonlink project for Private Record Linkage from Data61.

Install clkhash with pip:
