Re: [ANN] Nxt Bounty for working JavaScript code that signs and verifies signatures
Sources of what?
https://code.google.com/p/gvl/source/browse/crypt/curve25519.cpp?r=3c26171fd2d914484f03b7b63ca2065fa03a7aa3
And about "helloworld" false result: CfB said that this is normal behavior :O
As i can seen now, https://github.com/rev22/curve255js have nice performance only for one reason: it have simplified math, which can't work with negative numbers. This is reason, why "verify" used this math doesn't work.
The only thing not working is the is_negative function, right?
