Converting a .gho to a .vmdk that is password protected

Hello,

recently i learned to use the following command to convert our .gho's to .vmdk's:

ghost32 -clone,mode=restore,src=my.gho,dst=myimage.vmdk -batch –sure

The problem I'm running into is that alot of our .gho files are password protected and when i run this command i get the message:

ABORT : 30003, Password not provided for protected file.

I know the passwords to all of them but do not know where i should enter it in the above command line and in what format.

any help that can be provided would be great.

thanks!
