The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.
Libksba is a library to make the tasks of working with X.509 certificates, CMS data and related objects more easy. It provides a highlevel interface to the implemented protocols and presents the data in a consistent way.
Zlib is a free, general-purpose, not covered by any patents, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms.
A set of basic GNU tools commonly used in shell scripts
These are the GNU core utilities. This package is the combination of the old GNU fileutils, sh-utils, and textutils packages.
The GNU Secure Communication Protocol Library
GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols as well as APIs to parse and write X.509, PKCS #12, and other required structures. The project strives to provide a secure communications back-end, simple to use and integrated with the rest of the base Linux libraries. A back-end designed to work and be secure out of the box, keeping the complexity of TLS and PKI out of application code.
Utility for secure communication and data storage
GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG enables encryption and signing of data and communication, and features a versatile key management system as well as access modules for public key directories. GnuPG 2.0 adds support for smart cards and S/MIME encryption and signing to the base GnuPG package.
