Extended crypt library for descrypt, md5crypt, bcrypt, and others
Description
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.
This version of the library does not provide the legacy API functions
that have been provided by glibc's libcrypt.so.1.
