This is a non-official SPHINCS+ python implementation created from scratch based on SPHINCS+ algorithm of digital signatures which can be found at https://sphincs.org/.
DO NOT USE THIS PROGRAM FOR PROFESSIONNAL USE unless you know what you are doing. This work isn't official and hasn't been approved by anybody, it's main purpose was to understand how SPHINCS+ works and to try how we could use it. This program might have some flaws and is not meant to be fast.
Two folders contains SPHINCS+ algorithm, but only the package folder is recommanded to be used
- The main useful part of this code is located in the package folder, containing classes you can use to work with the algorithm.
- The src folder contain the same functions before they have been transformed into a class. Each Cryptographics methods are split in differents files (WOTS+, XMSS and FORS).
A Jupyter Notebook called Sphincs Example is provided to help you learn how to use the program.
Copy the package folder in your project root. Start by importing the SPHINCS Library:
from package.sphincs import Sphincs
And create an instance of SPHINCS+:
sphincs = Sphincs()
You can change SPHINCS+ parameters (n, w, w, d, k and a) using its provided functions:
sphincs.set_winternitz(4)
# Or
sphincs.set_w(4)
Generate a key pair: (Return a secret key and a public key)
sk, pk = sphincs.generate_key_pair()
Signing your message, message must be exprimed as bytes! (Return a signature)
m = b'What are quantum mechanics? I don't know. People who repair quantums, I suppose.'
signature = sphincs.sign(m, sk)
Verifying a signature: (Return True if signature is correct, False elsewere)
sphincs.verify(signature, m, pk)
