Cryptographic Library for Public Key Algorithms
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.
The libhogweed library contains public key algorithms to use with libnettle.
