7 /// \details <tt>config_ns.h</tt> provides defines for C++ and library
8 /// namespaces.
9 /// \details <tt>config.h</tt> was split into components in May 2019 to better
10 /// integrate with Autoconf and its feature tests. The splitting occurred so
11 /// users could continue to include <tt>config.h</tt> while allowing Autoconf
12 /// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
13 /// its feature tests.
14 /// \note You should include <tt>config.h</tt> rather than <tt>config_ns.h</tt>
15 /// directly.

34 /// \details Nearly all classes are located in the CryptoPP namespace. Within
35 /// the namespace, there are four additional namespaces.
36 /// <ul>
37 /// <li>Name - namespace for names used with NameValuePairs and documented
38 /// in argnames.h
39 /// <li>NaCl - namespace for NaCl test functions like crypto_box,
40 /// crypto_box_open, crypto_sign, and crypto_sign_open
41 /// <li>Donna - namespace for curve25519 library operations. The name was
42 /// selected due to use of Langley and Moon's curve25519-donna.
43 /// <li>Test - namespace for testing and benchmarks classes
44 /// <li>Weak - namespace for weak and wounded algorithms, like ARC4, MD5
45 /// and Pananma
46 /// </ul>
