NaCl (pronounced "salt") is an abbreviation for "Networking and Cryptography library", a public domain "...high-speed software library for network communication, encryption, decryption, signatures, etc".
NaCl was created by the mathematician and programmer Daniel J. Bernstein who is best known for the creation of qmail and Curve25519. The core team also includes Tanja Lange and Peter Schwabe. The main goal while creating NaCl, according to the paper, was to "avoid various types of cryptographic disasters suffered by previous cryptographic libraries".
- Authenticated encryption using Curve25519, Salsa20, and Poly1305.
- Signatures using Ed25519.
- Key agreement using Curve25519.
- Authenticated encryption using Salsa20 and Poly1305.
- Encryption using Salsa20 or AES.
- Authentication using HMAC-SHA-512-256.
- One-time authentication using Poly1305.
- No data flow from secrets to load addresses.
- No data flow from secrets to branch conditions.
- No padding oracles.
- Centralizing randomness.
- Avoiding unnecessary randomness.
- Extremely high speed.
NaCl has a variety of programming language bindings such as PHP, and forms the basis for Libsodium, a cross-platform cryptography library created in 2013 which is API compatible with NaCl.
- Libsodium — a portable, cross-compilable, installable, packageable, API-compatible version of NaCl.[third-party source needed]
- TweetNaCl — a tiny C library, which fits in just 100 tweets (140 symbols each), but supports all NaCl functions.[third-party source needed]
- NaCl for Tcl — a port to the Tcl language.[third-party source needed]
