Equihash implements the algorith as described in "Equihash: Asymmetric Proof-of-Work Based on the Generalized Birthday Problem" by Alex Biryukov and Dmitry Khovratovich, 2016, DOI:10.14722/ndss.2016.23108. This code, by Stefan Marsiske, is a fork of an ealier implementation by Khovratovich at https://github.com/khovratovich/equihash/ ; it provides a library, a C API and Python bindings. The cryptographic password storage SPHINX (pwdsphinx and libsphinx) depend upon equihash.
