(description
|
|
"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. \nNettle 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.")
