[SecureVNCPlugin] Password length?

Post by Troopers »

Hi,

I use the SecureVNCPlugin with AES-256
I want to have a unique encryption key for each session.
So, i can't use pkey and publickey file (because I don't know generate them dynamically)
I can't use a passphrase (because I don't know how to encrypt it in the ultravnc ini file)
then i could use the vnc password but the length is 8 characters.
I have tried to set the password more length (128 characters), it's works but i'm not sure that the 128 characters are used.

My question:
-is it possible to have a password of 128 length?
-if the password is 8 length, is the length of the encryption key?

Thanks
B

Nope, the VNC password in the ultravnc.ini file is limited to 8 characters, period. (as far as I know)

I believe that the SecureVNC passphrase is a separate entity (which overrides any existing UltraVNC password when the SecureVNC plugin is active).

Unfortunately I can't tell where the SecureVNC passphrase is stored, if it's stored at all! (Hopefully it is NOT stored anywhere, but merely used to generate private keys. Or something.)

I think the passphrase is stored in the ultravnc.ini file whith the DSMPlugin configuration, but i don't know how to crypt the passpharse to save it automatically in this file

Yes it is stored in the ultravnc.ini under DSMPluginConfig=

To automate the process for ChunkVNC I simply used AutoIt to control the GUI interface. I never did find another way to crypt (easily) a password for SecureVNC. Maybe a request for a SecureVNC command line passwd type executable is in order?

You might want to try contacting him directly http://adamwalling.com/SecureVNC/ as I'm sure he's as busy as the rest of us and might have missed this post.

Please report back if you get an answer.
