Laboratory work on cryptographic methods of information protection 👨💻
Pure python3 implementation of cryptograhic alogrithms
Oblivious transfer (OT) communications protocol message/response functionality implementations based on Curve25519 and the Ristretto group.
Oblivious pseudo-random function (OPRF) protocol functionality implementations based on Curve25519 primitives, including both pure-Python and libsodium-based variants.
Python library for Elliptic Curve Cryptography: key exchanges (Diffie-Hellman, Massey-Omura), ECDSA signatures, and Koblitz encoding. Suitable for crypto education and secure systems.
Here, I have made a very easy to use steganography tool. It allows for parties to communicate(bi-directionally) openly/publicly in "plain sight" but would only appear as the transferring of digital photos at fist glance. But, "hidden data" is actually embedded within the images. This tool allows for both extracting data from digital images as we…
Common cryptographic algorithms written in Python
Python code for different cryptographic algorithms
A basic cryptography library written in pure python, possible to use in CTF's
Easy-to-deploy oblivious pseudo-random function (OPRF) service that allows other parties (typically participants in some secure multi-party computation protocol) to obtain a persistent mask which they cannot decrypt but which they can safely apply (via requests to the service) to private data values of their choice.
ParallelCryptography harnesses high-performance computing to optimize cryptographic algorithms. Explore our subprojects for parallel encryption, decryption, hashing, and more. Secure your data efficiently with the power of parallel computing.
This is a voting system based on Azure Blockchain.
Python implementation of format preserving encryption defined as a NIST draft (FF1, FF3-1)
This is an encryption and decryption algorithm based on randomly generated integers
The Diffie-Hellman algorithm is being used to establish a shared secret that can be used for secret communications while exchanging data over a public network using the elliptic curve to generate points and get the secret key using the parameters.
