Subject: Password for V-Ray 1.5R4 Wanted! Quote message
Hi,
I have just downloaded V-Ray advanced 1.5R4 (vray_adv_150R4_max80_x86_pre_final3.rar), but I don’t know the password to open the RAR file. If you know the password, can you please give it to me? Thanks.

Does he actually think i am able to give him a password to a version that i(we) don’t have, because it has not been released yet!
So your undercover name is Yue_Hong, catchy . And i did answer him, i told him this

You have a lot of nerve asking me a password for a version that has not been released yet. I will post your message on the forum so other users are warned about you.
3.1.3. How to recover RAR passwords?
RAR/WinRAR archiver version 2.x used its proprietary, but rather strong encryption algorithm. At least no RAR 2.0 attacks were known except brute force.
Starting from version 3.0, RAR has been using a strong AES algorithm, which doesn’t allow any attacks more effective than the brute force. Besides, the encryption is implemented so that brute force speed on modern computer is very low, about 100 passwords per second. This carries inference that RAR 3.x system is the strongest between popular encryption systems in the context of brute force. This means you couldn’t recover RAR password longer than 6-7 symbols if you have no information about the password.
