• #decrypt(nonce, ciphertext, additional_data = nil)

  Decrypts and verifies an encrypted message with additional authenticated data

• #decrypt_string(nonce, ciphertext, additional_data = nil, encoding = "utf8")

  Same as #decrypt, but returns a String

• #do_decrypt(message, message_len, nonce, ciphertext, additional_data)
• #do_encrypt(ciphertext, ciphertext_len, nonce, message, additional_data)
• #encrypt(nonce, message, additional_data = nil)

  Encrypts and authenticates a message with additional authenticated data

• #encrypt_string(nonce, message, additional_data = nil)

  Same as #encrypt, but accepts a String message

• #key : Indexable(UInt8)
• #key_bytes

  The key bytes for the AEAD instance

• #nonce_bytes

  The nonce bytes for the AEAD instance

• #tag_bytes
