Source
do_encrypt(ciphertext, ciphertext_len, nonce, message, additional_data)
Source
encrypt(nonce, message, additional_data = nil)

Encrypts and authenticates a message with additional authenticated data

Source
encrypt_string(nonce, message, additional_data = nil)

Same as encrypt, but accepts a String message
