<div class="textblock"><p>Crypto++ interface to TweetNaCl library (20140917) </p>
<p>TweetNaCl is a compact reimplementation of the <a class="el" href="namespace_na_cl.html" title="Namespace containing NaCl library functions. ">NaCl</a> library by Daniel J. Bernstein, Bernard van Gastel, Wesley Janssen, Tanja Lange, Peter Schwabe and Sjaak Smetsers. The library is less than 20 KB in size and provides 25 of the <a class="el" href="namespace_na_cl.html" title="Namespace containing NaCl library functions. ">NaCl</a> library functions.</p>
<p>The compact library uses curve25519, <a class="el" href="struct_x_salsa20.html" title="XSalsa20 stream cipher. ">XSalsa20</a>, <a class="el" href="class_poly1305.html" title="Poly1305 message authentication code. ">Poly1305</a> and SHA-512 as default primitives, and includes both x25519 key exchange and ed25519 signatures. The complete list of functions can be found in <a href="https://tweetnacl.cr.yp.to/tweetnacl-20140917.pdf">TweetNaCl: A crypto library in 100 tweets</a> (20140917), Table 1, page 5.</p>
<p>Crypto++ rejects small order elements using libsodium's blacklist. The TweetNaCl library allowed them but the library predated the attack. If you wish to allow small elements then use the "unchecked" versions of crypto_box_unchecked, crypto_box_open_unchecked and crypto_box_beforenm_unchecked.</p>
<p>TweetNaCl is well written but not well optimzed. It runs 2x to 3x slower than optimized routines from libsodium. However, the library is still 2x to 4x faster than the algorithms <a class="el" href="namespace_na_cl.html" title="Namespace containing NaCl library functions. ">NaCl</a> was designed to replace.</p>
<p>The Crypto++ wrapper for TweetNaCl requires OS features. That is, <code>NO_OS_DEPENDENCE</code> cannot be defined. It is due to TweetNaCl's internal function <code>randombytes</code>. Crypto++ used <code><a class="el" href="class_default_auto_seeded_r_n_g.html" title="A typedef providing a default generator. ">DefaultAutoSeededRNG</a></code> within <code>randombytes</code>, so OS integration must be enabled. You can use another generator like <code><a class="el" href="class_r_d_r_a_n_d.html" title="Hardware generated random numbers using RDRAND instruction. ">RDRAND</a></code> to avoid the restriction. </p><dl class="section see"><dt>See also</dt><dd><a href="https://cr.yp.to/highspeed/coolnacl-20120725.pdf">The security impact of a new cryptographic library</a>, <a href="https://tweetnacl.cr.yp.to/tweetnacl-20140917.pdf">TweetNaCl: A crypto library in 100 tweets</a> (20140917), <a href="https://eprint.iacr.org/2017/806.pdf">May the Fourth Be With You: A Microarchitectural Side Channel Attack on Several Real-World Applications of Curve25519</a>, <a href="https://github.com/jedisct1/libsodium/commit/afabd7e7386e1194">libsodium commit afabd7e7386e1194</a> and <a href="https://tools.ietf.org/html/rfc7748">RFC 7748, Elliptic Curves for Security</a>, Section 6. </dd></dl>
