The Yubico PIV tool is used for interacting with the Privilege and Identification Card (PIV) application on a YubiKey. With it you may generate keys on the device, import keys and certificates, create certificate requests, and other operations. It includes a library and a command-line tool.

This package contains a Python module that forms the core of audit2allow, a part of the package policycoreutils. The sepolgen library contains: Reference Policy Representation, which are Objects for representing policies and the reference policy interfaces. It has objects and algorithms for representing access and sets of access in an abstract way and searching that access. It also has a parser for reference policy "headers". It contains infrastructure for parsing SELinux related messages as produced by the audit system. It has facilities for generating policy based on required access.

The policycoreutils package contains the core utilities that are required for the basic operation of an SELinux-enabled GNU system and its policies. These utilities include load_policy to load policies, setfiles to label file systems, newrole to switch roles, and run_init to run service scripts in their proper context.

This package provides the tools "checkpolicy" and "checkmodule". Checkpolicy is a program that checks and compiles a SELinux security policy configuration into a binary representation that can be loaded into the kernel. Checkmodule is a program that checks and compiles a SELinux security policy module into a binary representation.

SETools is a collection of graphical tools, command-line tools, and libraries designed to facilitate SELinux policy analysis.

The libsemanage library provides an API for the manipulation of SELinux binary policies.

The SELinux CIL compiler is a compiler that converts the common intermediate language (CIL) into a kernel binary policy file.

The libsepol library provides an API for the manipulation of SELinux binary policies. It is used by checkpolicy (the policy compiler) and similar tools, and programs such as load_policy, which must perform specific transformations on binary policies (for example, customizing policy boolean settings).

The libselinux library provides an API for SELinux applications to get and set process and file security contexts, and to obtain security policy decisions. It is required for any applications that use the SELinux API, and used by all applications that are SELinux-aware. This package also includes the core SELinux management utilities.

This package provides an implementation of OpenPGP's web of trust.

This Guix package is built to use the nettle cryptographic library.

Sequoia is a new OpenPGP implementation, written in Rust, consisting of several Rust crates/packages. This Guix meta-package combines these packages into a single one for convenience. Anyhow, you should not depend other packages on this one avoid excessive compile-times for users.

This package provides Sequoia's reimplementation of the GnuPG interface.

gpg-sq is Sequoia's alternative implementation of a tool following the GnuPG command line interface. It provides a drop-in but not feature-complete replacement for the GnuPG project's gpg.

This Guix package is built to use the nettle cryptographic library.

This package provides the command-line frontend for Sequoia OpenPGP.

This Guix package is built to use the nettle cryptographic library and the gpg-agent, openpgp-card and softkeys keystore backends.

sqv verifies detached OpenPGP signatures. It is a replacement for gpgv. Unlike gpgv, it can take additional constraints on the signature into account.

This Guix package is built to use the nettle cryptographic library.

Cap'n Proto is a very fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

FlatBuffers is a cross-platform serialization library for C++,C#, C, Go, Java, JavaScript, PHP, and Python. It was originally created for game development and other performance-critical applications.

This package provides a C version of the reader, parser and emitter for ruamel.yaml derived from libyaml.

The rencode module is a data structure serialization library, similar to bencode from the BitTorrent project. For complex, heterogeneous data structures with many small elements, r-encoding stake up significantly less space than b-encodings. This version of rencode is a complete rewrite in Cython to attempt to increase the performance over the pure Python module.

libnop is a header-only library for serializing and deserializing C++ data types without external code generators or runtime support libraries.

Apache Avro is a data serialization system. Avro provides:

1. Rich data structures;

2. a compact, fast, binary data format;

3. a container file, to store persistent data;

4. remote procedure call (RPC); and

5. simple integration with dynamic languages.

Code generation is not required to read or write data files nor to use or implement RPC protocols.

ckdl is a C library for parsing and emitting KDL. This package also provides kdlpp, a C++20 wrapper around ckdl.

This package provides the FlatBuffers serialization format for Python.

This package provides YAML parser/emitter that supports roundtrip preservation of comments, seq/map flow style, and map key order. It is a derivative of Kirill Simonov’s PyYAML 3.11. It supports YAML 1.2 and has round-trip loaders and dumpers. It supports comments. Block style and key ordering are kept, so you can diff the source.
