The security impact of a new cryptographic library

Abstact : This paper introduces a new cryptographic library, NaCl, and explains how the design and implementation of the library avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL.

Introduction
For most cryptographic operations there exist widely accepted standards, such as the Advanced Encryption Standard (AES) for secret-key encryption and 2048-bit RSA for public-key encryption. These primitives have been extensively studied, and breaking them is considered computationally infeasible on any existing computer cluster.

For each of these cryptographic primitives there exist various implementations and software libraries, and it has become common best practice in the development of secure systems to use the implementations in these libraries as building blocks. One should thus expect that the cryptographic layer of modern
