Please don&#x27;t use this library. Nacl is much safer, and in fact smaller.<p>If you&#x27;re worried about size, use Tweetnacl:<p><i>TweetNaCl is the world&#x27;s first auditable high-security cryptographic library. TweetNaCl fits into just 100 tweets while supporting all 25 of the C NaCl functions used by applications. TweetNaCl is a self-contained public-domain C library, so it can easily be integrated into applications.</i>
