Partial/future CFFI for Haxe/Neko to the awesome mbed TLS
(or, for now, fast hash functions for Haxe/Neko)
When possible, the Haxe APIs follow their existing haxe.crypto.* counterparts, so that the library can be a simple to adopt performance upgrade.
Additionally, lower-level and even more efficient APIs are provided as well.
For more information, check the complete API documentation.
// Test.hx
class Test {
static function main()
{
// use the haxe.crypto.* style APIs for convenience
var fox = "The quick brown fox jumps over the lazy dog";
trace(mbedtls.Sha512.encode(fox));
// or the streaming APIs to be able to process large ammounts of data
var buf = haxe.io.Bytes.alloc(1 << 20); // 1 MiB
buf.fill(0, buf.length, "x".code);
var hash = new mbedtls.Sha512();
for (i in 0...1024) // total data processed: 1 GiB
hash.update(buf, 0, buf.length);
trace(hash.finish().toHex());
}

The original purpose of starting this library was to provide a very substantial performance boost for modules running on Tora that compute a lot of hashes, either for password hashing, file deduplication/identification or other use cases.
Even with interpreter and CFFI overhead, performance is now much closer to the <hash>sum utilities from coreutils, both in cpu time and memory consumption.
