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.

FreeRADIUS Client is a library for writing RADIUS Clients. The library lets you develop a RADIUS-aware application in less than 50 lines of C code.
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.
FreeRADIUS Client is a framework and library for writing RADIUS Clients. This package includes radius client test utilities such as, radiusclient, radexample, radstatus, radembedded and radacct.
