/*
* WARNING: This is just a stream cipher. It is NOT authenticated encryption.
* While it provides some protection against eavesdropping, it does NOT
* provide any security against active attacks.
* Furthermore, this implementation was not part of NaCl.
*
* If you are looking for a stream cipher, you might consider
* crypto_stream_aes128ctr, crypto_stream_chacha20 or crypto_stream_(x)salsa20
* which are timing-attack resistant.
*
* But unless you know what you're doing, what you are looking for is probably
* the crypto_box or crypto_secretbox functions.
