The NaCl constructions are available in pretty much all programming
languages, making them a solid choice for applications that require
interoperability.
Go includes them in the standard library, JavaScript has the popular
tweetnacl.js module, and reimplementations and ports of TweetNaCl
have been made everywhere.
Zig has almost everything that NaCl has at this point, the main
missing component being the Salsa20 cipher, on top on which NaCl's
secretboxes, boxes, and sealedboxes can be implemented.
So, here they are!
And clean the X25519 API up a little bit by the way.
