Free, open source C++ library, offering some basic functionality to build high-performing, platform-independent programs. Some of the highlights include:

Puremagic is a pure-Python module to identify files by their magic numbers. It is fast, lightweight, minimalistic, cross-platform, and doesn't have dependencies. It can serve as a stand-in for python-magic, but its own magic_file() and magic_string() function are more powerful and also display a confidence score and possible duplicate matches.

Mirage-crypto provides symmetric ciphers (DES, AES, RC4, ChaCha20/Poly1305), and hashes (MD5, SHA-1, SHA-2).

This package provides support files for the Linux kernel build, e.g. scripts to handle ABI information and for generation of build system meta data.

go-jose aims to provide an implementation of the Javascript Object Signing and Encryption set of standards. This includes support for JSON Web Encryption, JSON Web Signature, and JSON Web Token standards.

This library provides tools to interact with Jandy iAqualink systems, allowing users to control and monitor various aspects of their pool equipment remotely. Support is included for various device types such as binary sensors, climate controls, lights, and switches. The library communicates with the iAqualink cloud service to facilitate remote management of pool settings including temperature control, pump operation, and light settings.
