#includeThis example demonstrates how to use the libsodium library to generate a random key for use with the XChaCha20-Poly1305 cipher. The key is stored in a CKey object and can then be used to encrypt or decrypt data using the cipher. Package Library: libsodiumint main() { unsigned char key[crypto_secretstream_xchacha20poly1305_KEYBYTES]; crypto_secretstream_xchacha20poly1305_keygen(key); // Use the key to encrypt or decrypt data // ... return 0; }
