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.
.
It tries to solve a problem of providing a common set of cryptographic
algorithms for higher-level applications by implementing a
context-independent set of cryptographic algorithms. In that light, Nettle
doesn't do any memory allocation or I/O, it simply provides the
cryptographic algorithms for the application to use in any environment and
in any way it needs.
.
This package contains the asymmetric cryptographic algorithms, which,
require the GNU multiple precision arithmetic library (libgmp) for
their large integer computations.
