NaCl (software) NaCl (software) <dfn>NaCl</dfn> (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". Reference implementation is written in C, often with several inline assembler. C++ and Python are handled as wrappers. NaCl
Spiro compound compounds. Spiro compound A spiro compound, or spirane, from the Latin "spīra", meaning a twist or coil, is a chemical compound, typically an organic compound, that presents a twisted structure of two or more rings (a ring system), in which 2 or 3 rings are linked together by one common atom, examples of which are shown at right. The simplest spiro compounds are bicyclic (having just two rings), or have a bicyclic portion as part of the larger ring system, in either case with the two rings connected through the defining single common atom. The one common atom connecting the
