Noise (#90) * Start ChaCha20Poly1305 integration (BearSSL) * Add Curve25519 (BearSSL) required operations for noise * Fix curve mulgen iterate/derive * Fix misleading header * Add chachapoly proper test * Curve25519 integration tests (failing, something is wrong) * Add few converters, finish c25519 integration tests * Remove implicit converters * removed internal globals * Start noise implementation * Fix public() using proper bear mulgen * Noise protocol WIP * Noise progress * Add a quick nim version of HKDF * Converted hkdf to iterator, useful for noise * Noise protocol implementation progress * Noise progress * XX handshake almost there * noise progress * Noise, testing handshake with test vectors * Noise handshake progress, still wrong somewhere! * Noise handshake success! * Full verified noise XX handshake completed * Fix and rewrite test to be similar to switch one * Start with connection upgrade * Switch chachapoly to CT implementations * Improve HKDF implementation * Use a type insted of tuple for HandshakeResult * Remove unnecessary Let * More cosmetic fixes * Properly check randomBytes result * Fix chachapoly signature * Noise full circle (altho dispatcher is nil cursed) * Allow nil aads in chachapoly routines * Noise implementation up to running full test * Use bearssl HKDF as well * Directly use bearssl rng for curve25519 keys * Add a (disabled/no CI) noise interop test server * WIP on fixing interop issues * More fixes in noise implementation for interop * bump chronos requirement (nimble) * Add a chachapoly test for very small size payloads * Noise, more tracing * Add 2 properly working noise tests * Fix payload packing, following the spec properly (and not go version but rather rust) * Sanity, replace discard with asyncCheck * Small fixes and optimization * Use stew endian2 rather then system endian module * Update nimble deps (chronos) * Minor cosmetic/code sanity fixes * Noise, handle Nonce max * Noise tests, make sure to close secured conns * More polish, improve code readability too * More polish and testing again which test fails * Further polishing * Restore noise tests * Remove useless Future[void] * Remove useless CipherState initializer * add a proper read wait future in second noise test * Remove noise generic secure implementation for now * Few fixes to run eth2 sim * Add more debug info in noise traces * Merge size + payload write in sendEncryptedMessage * Revert secure interface, add outgoing property directly in newNoise * remove sendEncrypted and receiveEncrypted * Use openarray in chachapoly and curve25519 helpers
