Summary Extended crypt library for DES, MD5, Blowfish and others
Description libxcrypt is a modern library for one-way hashing of passwords. It supports DES, MD5, SHA-2-256, SHA-2-512, and bcrypt-based password hashes, and 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. On Linux-based systems, by default libxcrypt will be binary backward compatible with the libcrypt.so.1 shipped as part of the GNU C Library. This means that all existing binary executables linked against glibc's libcrypt should work unmodified with this library's libcrypt.so.1. We have taken pains to provide exactly the same "symbol versions" as were used by glibc on various CPU architectures, and to account for the variety of ways in which the Openwall extensions were patched into glibc's libcrypt by some Linux distributions. (For instance, compatibility symlinks for SuSE's "libowcrypt" are provided.) However, the converse is not true: programs linked against libxcrypt will not work with glibc's libcrypt. Also, programs that use certain legacy APIs supplied by glibc's libcrypt ('encrypt', 'encrypt_r', 'setkey', 'setkey_r', and 'fcrypt') cannot be compiled against libxcrypt.
