I pushed a version with the testvector. The hmac signatures match.The
aes_key entry matches the aes_key concatenated with the hmac_key. What
is the "ecies_key_derivation" entry? Greetings!

no it does not work with the testvector. The problem is the new
version of bitcoinjs-lib . The code from the twister-html repo is
incompatible with the new version. They changed some method
signatures.
hmmm, got it.
we may compare intermediate steps to pinpoint where it starts to fail
(eg. the "secret" derived from EC multiplication before computing the
sha512 etc).
Also i find it strange to use an empty buffer als iv. Thoughts
thats just for the testvector.
That's correct: the IV is actually initialized to all zeros (16
bytes), see here
https://github.com/miguelfreitas/twister-core/blob/master/src/key.cpp#L379
Which is fine, btw, since we don't reuse the key between DMs.
(You may try if "empty IV" is the same as "all zeros IV" for this new
bitcoinjs-lib)

Miguel
