Achieving RSA Blind Signatures

Blockchain-Voting System

RSA Blind Signatures from Python

Minimal client/server demo using blind RSA signatures for registration and login. Clients generate credentials, blind-sign with the server, store an encrypted blob locally (and on the server for cross-device use), and never send the user password over the wire.

C implementation of a blind signature protocol based on ZKBoo (MPC-in-the-Head), using MSS (Merkle Signature Scheme) coupled with WOTS as the underlying one-time signature (OTS).
