NaCl (pronounced salt ) and the sodium based on it , also called libsodium , are cryptography - program libraries that are modern, easy to use, secure, fast, free and open source software .

They are used in Discord , Dovecot , KeePassXC , PowerDNS , Saltstack , Stellar , Threema , Tox , Wire and WordPress . Sodium has been part of the PHP language core since 2017 .

Among other things, the libraries offer functions for three hash types as well as symmetrical and asymmetrical authentication , encryption and decryption .

NaCl

The NaCl core development team consists of Daniel J. Bernstein , Tanja Lange and Peter Schwabe. NaCl is programmed in C, some speed-critical parts in assembler . There are interfaces for the programming languages C , C ++ and Python , but only Unix-like operating systems are supported .

Sodium

Sodium is a further development of NaCl, which supports additional operating systems and interfaces to over 30 programming languages. Not least because of the inclusion of sodium in the PHP language core in 2017, its spread has increased significantly.

Names

NaCl is the abbreviation for “Networking and Cryptography Library”; it does not provide any network functionality, but network software can use it. Salt in cryptology denotes an additional character string for passwords . Table salt is sodium chloride with the chemical formula NaCl, which explains the pronunciation “salt” in the NaCl library. The sodium contained in table salt is also called sodium. The frequently used variant "libsodium" corresponds to the Linux naming convention for dynamic libraries .
