  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
