Frank Denis	e59dd7eecf	std/crypto/x25519: return encoded points directly + ed->mont map ... Leverage result location semantics for X25519 like we do everywhere else in 25519/* Also add the edwards25519->curve25519 map by the way since many applications seem to use this to share the same key pair for encryption and signature.	2020-10-29 14:39:58 -04:00
Frank Denis	5764c550ed	std/crypto: vectorize Salsa20 ... 20% faster on x86_64, slower on aarch64 as usual :/	2020-10-29 14:34:58 -04:00
Frank Denis	ea45897fcc	PascalCase *box names, remove unneeded comptime & parenthesis ... Also rename (salsa20|chacha20)Internal() to a better name. And sort reexported crypto.* names	2020-10-28 21:43:15 +02:00
Frank Denis	74a1175d9d	std/*: add missing MIT license headers	2020-10-26 17:41:29 +01:00
Frank Denis	28fb97f188	Add (X)Salsa20 and NaCl boxes ... 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.	2020-10-25 18:04:12 +01:00
