晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

What is GNU Nettle? A quote from the introduction in the Nettle Manual:

  Nettle is a cryptographic library that is designed to fit easily in more
  or less any context: In crypto toolkits for object-oriented languages
  (C++, Python, Pike, ...), in applications like LSH or GNUPG, or even in
  kernel space. In most contexts, you need more than the basic
  cryptographic algorithms, you also need some way to keep track of available
  algorithms, their properties and variants. You often have some algorithm
  selection process, often dictated by a protocol you want to implement.
  
  And as the requirements of applications differ in subtle and not so
  subtle ways, an API that fits one application well can be a pain to use
  in a different context. And that is why there are so many different
  cryptographic libraries around.
  
  Nettle tries to avoid this problem by doing one thing, the low-level
  crypto stuff, and providing a simple but general interface to it.
  In particular, Nettle doesn't do algorithm selection. It doesn't do
  memory allocation. It doesn't do any I/O.
  
  The idea is that one can build several application and context specific
  interfaces on top of Nettle, and share the code, test cases, benchmarks,
  documentation, etc. Examples are the Nettle module for the Pike
  language, and LSH, which both use an object-oriented abstraction on top
  of the library.

GNU Nettle is free software; you can redistribute it and/or modify it
under the terms contained in the files COPYING* (see the manual for
information on how these licenses apply).

If you have downloaded a Nettle release, build it with the usual
./configure && make && make check && make install (see the INSTALL
file for further instructions).

You can also get Nettle from git, see
http://www.lysator.liu.se/~nisse/nettle/ for current instructions. In
particular, you need to run the ./.bootstrap script after checkout and
before running ./configure.

Read the manual. Mail me if you have any questions or suggestions.
