Looking for a replacement method to encode/decode the ( phrase || privateKey ) <> keystore

Thinking about the keystore file format compatible to ethereum's system, however is not so efficiency. But it still worth finding a replacement to the format.

In dart, to implement the keystore encode/decode, one has to combine the scrypt and pbkdf2 to it. The easiest way to complete the job is to borrow the code from web3dart or laksadart I previously built for Zilliqa. However the encoding speed is too slow because of scrypt algorithm is slow.

Another option is to use FFI from other native library like ethsign , it is fast and run smoothly when I tried to bind it to the dynamic library. However, in rust we generally use serde_json to encode the Crypto object, the serde_json will be binded too, which will largely increase the bundle's size.

I don't have enough time to do enough search to finish the task. So if you have idea or solution, please comment or reply.

1. A replacement standard or format for keystore.
2. A fast and efficient way to encode/decode using FFI or pure dart code.
3. Any other good ideas
