Hi all, I've found the decryption func in dffnt.exe here:
https://pastebin.com/KvkjYUrr

The Key is ahcTaNwLcATRE... and three bytes E2,5E,C8.

I am a noob to Cryptography and cannot recognize this, hope some of you can help.

BTW KT's doaxvv use the same algorithm.

I haven't update vv, and it's not runable on my pc now...

you can try find the key yourself, take the (outdated) doax_vv.exe below as example:
https://mega.nz/#!LjpABYpR!Y7FaF06WYfuS ... UyLvbIdSHA

1400FEEA0 (file offset FE2A0) is the decrypt function, find that in the current vv executable,
then you can get the key string in ram.
