* Package name : pyequihash Version : 0.2 Upstream Author : Stefan Marsiske <sph...@ctrlc.hu> * URL : https://github.com/stef/equihash/python * License : GPLv3 Programming Lang: Python Description : python bindings for libequihash: memory-hard Proof-of-Work with fast verification Binary package name: python3-equihash 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. . This package offers a Python wrapper for the C library and comes with functions equihash.solve(n, k, seed) and equihash.verify (n,k,seed,sol). See https://www.ctrlc.hu/~stef/blog/posts/sphinx.html and https://nlnet.nl/project/OpaqueSphinxServer/ for more background information. See e.g. https://core.ac.uk/download/pdf/31227294.pdf for a copy of the original article. The SPHINX project was funded through the NGI0 PET Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 825310. I intend to carry out this work within the Debian Python Team, at the yet to be created https://salsa.debian.org/python-team/packages/pyequihash . The libequihash package which is now in unstable ( see https://tracker.debian.org/pkg/libequihash ) currently holds the same python code. I'll upload a new version of this original libequihash package without the python wrapper code; it will no longer build python3-equihash. Packaging pyequihash from this pypi upstream sources is done in order to simplify the Debian packaging work (and by doing so fix some RC bugs). Bye, Joost
