The crypto_box_keypair function randomly generates a secret key and a corresponding public key. It puts the secret key into sk and returns the public key
The crypto_box function encrypts and authenticates a message m using the sender's secret key sk, the receiver's public key pk, and a nonce n. The crypto_box function returns the resulting ciphertext c
The crypto_box_open function verifies and decrypts a ciphertext c using the receiver's secret key sk, the sender's public key pk, and a nonce n. The crypto_box_open function returns the resulting plaintext m.
