  43     (description
  44      "Nettle is a cryptographic library that is designed to fit easily
  45 in more or less any context: In crypto toolkits for object-oriented
  46 languages (C++, Python, Pike, ...), in applications like LSH or GNUPG,
  47 or even in kernel space.  In most contexts, you need more than the basic
  48 cryptographic algorithms, you also need some way to keep track of
  49 available algorithms, their properties and variants.  You often have
  50 some algorithm selection process, often dictated by a protocol you want
  51 to implement.
  52
  53 And as the requirements of applications differ in subtle and not so
  54 subtle ways, an API that fits one application well can be a pain to use
  55 in a different context.  And that is why there are so many different
  56 cryptographic libraries around.  \nNettle tries to avoid this problem by
  57 doing one thing, the low-level crypto stuff, and providing a simple but
  58 general interface to it.  In particular, Nettle doesn't do algorithm
  59 selection.  It doesn't do memory allocation. It doesn't do any I/O.")
