Zero-Knowledge Proofs Project

Protocol Demonstration of 1-2 Oblivious Transfer Protocol & Zero Knowledge Protocol for Network Security Lectures.

Zero_Knowledge-proof demonstration using discrete log. Demonstration of 1-2 oblivious transfer protocol.

Keeper Security Manager application vault access. Meant to be served behind a protected API enpoint, returns records as json.

Secure Vault backend provides a zero-knowledge REST API for storing and sharing encrypted secrets. Built with Spring Boot and Spring Security, it supports JWT authentication, MFA, Google OIDC login, and role-based access control for Admin, Team Lead, and Developer users. All secrets remain encrypted; the server never has access to plaintext data.

Java implementation of the Schnorr protocol

A Java framework to write circuits/constraints for zk-SNARKs.

Public Key Infrastructure (PKI) system and Zero-Knowledge Password Vault. Features hierarchical X.509 certificate management, recursive trust chain validation, and client-side asymmetric key wrapping.

A Java implementation of the Schnorr zero-knowledge enity authentication protocol using the Bouncy Castle criptographic library.
