crypto_lab

A Python Streamlit-based web application for experimenting with cryptographic algorithms and protocols using PyCryptodome.

Features

  • Interactive web UI for cryptographic demos, including:
  • SHA-256 hashing
  • Random number generation
  • HMAC (SHA-256)
  • Key derivation functions (PBKDF2, scrypt, HKDF)
  • AES encryption (CBC mode)
  • RSA encryption and key transport
  • ECC key generation
  • Digital signatures (RSA)
  • Shamir's Secret Sharing

Getting Started

Running the Web Application

  • Launch the Streamlit web app using the main entry point: python -m crypto_lab.run_web_app [--server-address ADDRESS] [--server-port PORT]
  • --server-address: Address to bind the Streamlit server (default: system FQDN)
  • --server-port: Port to run the Streamlit server on (default: 8503)
