registry password

[sgt-d]

this has probably been covered a million times, i'm just not finding the information anywhere, so i thought i'd ask.

i am writing a delphi gui for distributing ultr@vnc and i need to add a password field to my gui that can be used to set the normal winvnc password.

i have a mixture of operating systems on the network, including 9x,nt,2k,xp, etc... so i can't use .reg files, and i'd rather avoid using them anyway because they are static in nature.

so, a dynamic password field is going to be used.

in winvnc i entered the password as "testing", no quotes.

in my edit box i also typed "testing", again, no quotes.

this is the line that enters the binary_data into the registry:

reg.writebinarydata('password2',pchar('testing')^,8);

but as you can see, i get different results:

winvnc: "Password"=hex:d7,88,a1,63,44,6f,47,32
my edit: "password2"=hex:74,65,73,74,69,6e,67,00

so my question i guess is... how is the winvnc edit box writing the data to the registy? i ran an ascii -> hex converter on a few sites, and what you see above for "password2" is 100% correct for "hex" values. is the password encrypted or something?

vnc use a fix key des encryption....
Encrypted, but not that secure..as the key is fixed

ok. that leads to two more quick questions...

if i save the password unencrypted... will it still work?

if not, how can i encrypt it so that it will work?

You need to rewrite the
vncEncryptPasswd function in delphi and add it.
