Add WAVES walletgenerator, sign and verify messages

[username1565]

Can you add WAVES in walletgenerator.net?
https://github.com/PyWaves/wallet-generator
I just don't understand how to coding this in JavaScript.
Also, there is using another elliptic curve: https://github.com/wavesplatform/waves-documentation/blob/master/en/blockchain/waves-protocol/cryptographic-practical-details.md
And maybe, you, as programmer, can find this all algorithms implemented in JavaScript.

The simply waves wallet generator you can see here:
https://username1565.github.io/waves-lite-client/
source code - here: https://github.com/username1565/waves-lite-client
Also, there is available sign and verify messages locally, like here:
https://username1565.github.io/brainwallet.github.io/#sign
https://username1565.github.io/brainwallet.github.io/#verify

But signing and verify messages for WAVES, there is just as functions inside the main JavaScript.
So... Can you add ability to sign and verify messages in walletgenerator.net?
