1libxcrypt is a modern library for one-way hashing of passwords. It supports a
2wide variety of both modern and historical hashing methods: yescrypt,
3gost-yescrypt, scrypt, bcrypt, sha512crypt, sha256crypt, md5crypt, SunMD5,
4sha1crypt, NT, bsdicrypt, bigcrypt, and descrypt. It provides the traditional
5Unix crypt and crypt_r interfaces, as well as a set of extended interfaces
6pioneered by Openwall Linux, crypt_rn, crypt_ra, crypt_gensalt,
7crypt_gensalt_rn, and crypt_gensalt_ra.

9libxcrypt is intended to be used by login(1), passwd(1), and other similar
10programs; that is, to hash a small number of passwords during an interactive
11authentication dialogue with a human. It is not suitable for use in bulk
12password-cracking applications, or in any other situation where speed is more
13important than careful handling of sensitive data. However, it is intended to be
14fast and lightweight enough for use in servers that must field thousands of
15login attempts per minute.
