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.
