We started from learning programming with crypto at Universities (6 connected Universities in Poland), we voted for programming friendly cryptocurrency, we chose litecoin, we did unexpeced very fast api/wallet for litecoin, after presentations we get customer who want Dash and Dogecoin, we said ok (not all crypto will work that fast, these can)

minitalk - A small talk server and client for Tor Hidden Services, so that Alice and Bob can talk to each other directly.

JavaScript Library for Elliptic Curve Cryptography: key exchanges (Diffie-Hellman, Massey-Omura), ECDSA signatures, and Koblitz encoding. Suitable for crypto education and secure systems.

🔐 A collection of cryptographic algorithms implemented from scratch in Python, including hashing, encryption, and secure key exchange.

All the Programs of the 7th Sem Cyber Security Lab with their output in different steps. This lab provides students with hands-on experience in implementing and understanding fundamental cybersecurity concepts. It focuses on practical exposure to key security areas such as cryptography, network security, vulnerability assessment, secure code.

The Elliptic Curve Data Protocol (ECDP) is a P2P communication protocol for decentralized networks, utilizing elliptic curve cryptography (ECC) for encryption, ECDSA for message authentication, and Diffie-Hellman key exchange for secure sessions. It operates over TCP and UDP.

"A collection of implemented symmetric and asymmetric cryptographic algorithms."
