I am wondering how curve25519 is implemented, but without any notes, I just can not understand it at all. anyone can shed some lights on it?

Hi, this whole implementation looks like a direct port from a reference C/C++ impl; I can see many identical calls. And because it is a reference impl. is will be slow, also after quickly reviewing the code of Salsa20, there is still a room to optimize.

You may be better to go with BouncyCastle on Java.
