Client library and command line tools for memcached server
Memcached is an in-memory key-value store for small arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. libmemcached is a C/C++ client library and tools for the memcached server (http://memcached.org/).

Commands for Manipulating Filesystem Extended Attributes
A set of tools for manipulating extended attributes on filesystem objects, in particular getfattr(1) and setfattr(1). An attr(1) command is also provided which is largely compatible with the SGI IRIX tool of the same name.
Library for supporting access control list
This package contains the library for manipulating access control list.
systemd is a system and service manager that runs as PID 1 and starts the rest of the system.
Extended crypt library for DES, MD5, Blowfish and others
libxcrypt is a modern library for one-way hashing of passwords. It supports a wide variety of both modern and historical hashing methods: yescrypt, gost-yescrypt, scrypt, bcrypt, sha512crypt, sha256crypt, md5crypt, SunMD5, sha1crypt, NT, bsdicrypt, bigcrypt, and descrypt. It provides the traditional Unix crypt and crypt_r interfaces, as well as a set of extended interfaces pioneered by Openwall Linux, crypt_rn, crypt_ra, crypt_gensalt, crypt_gensalt_rn, and crypt_gensalt_ra. libxcrypt is intended to be used by login(1), passwd(1), and other similar programs; that is, to hash a small number of passwords during an interactive authentication dialogue with a human. It is not suitable for use in bulk password-cracking applications, or in any other situation where speed is more important than careful handling of sensitive data. However, it is intended to be fast and lightweight enough for use in servers that must field thousands of login attempts per minute.
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.
The GNU Find Utilities are the basic directory searching utilities of the GNU operating system. These programs are typically used in conjunction with other programs to provide modular and powerful directory search and file locating capabilities to other commands. The tools supplied with this package are: find - search for files in a directory hierarchy locate - list files in databases that match a pattern updatedb - update a file name database xargs - build and execute command lines from standard input
simplify the administration of log files
The logrotate utility is designed to simplify the administration of log files on a system which generates a lot of log files. Logrotate allows for the automatic rotation compression, removal and mailing of log files.logrotate Logrotate can be set to handle a log file daily, weekly, monthly or when the log file gets to a certain size.
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.
A library for getting and setting POSIX.1e draft 15 capabilities
This is a library for getting and setting POSIX.1e (formerly POSIX 6) draft 15 capabilities.
Flexible, stable and highly-configurable FTP server
ProFTPD is an enhanced FTP server with a focus toward simplicity, security, and ease of configuration. It features a very Apache-like configuration syntax, and a highly customizable server infrastructure, including support for multiple 'virtual' FTP servers, anonymous FTP, and permission-based directory visibility. This package defaults to the standalone behavior of ProFTPD, but all the needed scripts to have it run by systemd instead are included.
Bash is the GNU Project's shell. Bash is the Bourne Again SHell. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.
Libidn2 is a free software implementation of IDNA2008, Punycode and TR46. Its purpose is to encode and decode internationalized domain names.
Pluggable Authentication Modules for Linux
PAM (Pluggable Authentication Modules) is a system of libraries that handle the authentication tasks of applications (services) on the system.
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.
Sodium is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing and more. It is a portable, cross-compilable, installable6, packageable fork of NaCl, with a compatible API, and an extended API to improve usability even further. Its goal is to provide all of the core operations needed to build higher-level cryptographic tools.
PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there are no C++ wrappers. The distribution does contain a set of C wrapper functions for the 8-bit library that are based on the POSIX regular expression API (see the pcre2posix man page). These are built into a library called libpcre2-posix. Note that this just provides a POSIX calling interface to PCRE2; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE2's facilities.
A general purpose cryptography library with TLS implementation
The openssl-libs package contains the libraries that are used by various applications which support cryptographic algorithms and protocols.
