JCryptL

This is a bare-bones mathematical encryption library for educational purposes only. It processes data and implements basic encryption protocols

WARNING: DO NOT USE IN PRODUCTION

This implementation is NOT secure and should NOT be used for actual encryption. It lacks:

• Proper padding (vulnerable to padding oracle attacks)
• Adequate key sizes (uses small keys that can be broken)

For real applications, use cryptographic libraries like OpenSSL, Libsodium, among others.

Usage Example

// Generate key pair
auto keys = crypto::rsa::generate_keypair();
    
// Original message
std::string message = "Test Message 123";
std::vector<uint8_t> data(message.begin(), message.end());
    
// Encrypt
auto encrypted = crypto::rsa::encrypt(data, keys.public_key);
    
// Decrypt
auto decrypted = crypto::rsa::decrypt(data, keys.private_key);

// Print decrypted message
std::cout << std::string(decrypted.begin(), decrypted.end());
